Common Car Stereo Problems, Symptoms and Solutions: Aftermarket Stereos

Common Car Stereo Problems

Aftermarket stereos can be a pain if they aren’t functioning properly. Here is a list of your common car stereo problems, symptoms and solutions to help get your stereo up and running!

Problem: Can’t Find an Accessory/Ignition Power

Possible Solution:

–          In some cases, car stereos do not come wired with a 12v Accessory/Ignition wire, making an aftermarket radio difficult to install and work properly. Many Jeeps and Chevrolet systems have a data signal wire that carries a very low voltage signal that tells the OEM Head Unit when to turn on, however; it is not compatible with aftermarket units. The easiest way to locate an Accessory/Ignition wire is to find a cigarette lighter that turns on when the car does. Get behind the lighter and tap into the positive wire and connect it to your RED Accessory/Ignition wire on your aftermarket wire harness.

Problem: Head Unit has Power but no Sound

Possible Solution:

–          Many cars have built in amplifiers that require a 12v signal to be sent in order to turn on the Amplifier, most common being Bose, Infinity, and JBL. If your car has any of these systems, check your AMP TURNON signal wire for 12v. Blue/White wire located on Head Unite wire harness.

Problem: Installed an Aftermarket Head Unit and Now it Has No Power

Possible Solution:

–          First off, check your wiring. If you have a voltage meter or a test light, test the ground (black), constant 12v (yellow), and accessory 12v (red) wires to make see if you have the correct voltage in the correct wires, as well as a good ground. Constant will always be 12v, whether or not your car is on. Accessory will be 12v only when you turn the key to the “ON” position or the car is running. Make sure to use your ground, as well as another ground (like the frame or body of the car) while testing your constant and accessory to test that you have a good ground.

If you find that one of your power wires or ground wires are not correct, check your vehicle wire diagram and make sure you have the correct corresponding power and ground wires.

–          If you do not have power, and you know for a fact your wiring is correct, check the fuses under the dash or under the hood (depending on your vehicle). Easiest way to locate the correct fuse is to look in the Owner’s Manual and find the fuse number and box location. Your manual should indicate which fuse is for the “Accessory”, “Car Stereo”, or something of that sort. After finding the location of the fuse, pull it and make sure that the leads are not corroded and that the fuse has not been broken or popped.
–          If your speakers randomly stopped working and you noticed that your amplifier is in protection mode, there are a few reasons why this might have happened.

  • Most aftermarket amplifiers have a protection from low and high voltage. If your alternator is producing too much power, it will trigger the amplifier’s protection mode. Vice versa, if your battery is low and the amplifier is not receiving a constant 12v, it will enter protection mode.
  • Amplifiers will also enter protection mode if there is a short somewhere. If you have a signal RCA wire that is shorting out, this could be your problem so check to see if your RCAs are in-tact and not shorted. Also, if one of the output channels are shorted out, or you have a blown speaker, many aftermarket amplifiers will enter protection mode. Disconnect all output channels and see if it will return to normal operation.

Problem: Alternator Wine

Possible Solution:

–          If you hear a wining noise that fluctuates with the RPMs of your vehicle, and lessens when the car engine is turned off, you are dealing with Alternator Wine. Alternator Wine is cause by having a bad ground to either your head unit or your speakers’ amplifier. Check your ground wires and find a better place to ground them, e.g. the frame or body of the car.
–          If you are experiencing headlight dimming when you have your radio turned up with aftermarket amplifiers and subwoofers, your stereo is pulling too much power for the alternator to keep up. There are a few solutions to this problem:

  • Wire in a Capacitor. Although curing headlight dim is far down on the list for a Capacitor’s use, a capacitor might be the solution to your problem. A capacitor is made to curve the spikes in power from the battery to the Amplifier, to create consistent 12v power. Adding a capacitor with the correct farad, in some cases, will curve your amplifier power drawing spikes enough to limit headlight dim. The rule of thumb farad – wattage conversion is 1 farad to every 1000 watts.
  • Upgrade the Alternator. Sometimes OEM alternators don’t generate enough power for your upgraded stereo. Upgrading the alternator to one that can produce enough power to handle your upgraded amplifiers/stereo will solve your headlight dim.
  • Get a Bigger/Better Battery: Sometimes old/cheap batteries can be one of the sources in your headlight dim issue. Replace your battery to a newer, bigger batter to handle more power and load. Although this might not fix the problem it might help.
  • Add an Auxiliary Battery: Wire in a completely separate battery to power just your stereo. This will lessen the load on your engine battery and sometimes will fix your headlight dim.

        I have a 2000 Civic. I have put in 2 aftermarket decks. The first deck, had power, was all lit up but I couldnt turn up or down the volume or change the source. NO BUTTONS worked at all. I thought it was an internal problem with the unit, so i changed it. I put in a Sony Xplode that i had from one of my other cars. Worked great until today! when i was driving home from work, i turned up the volume a bit and it kept increasing. I couldnt turn it down. I couldnt change the source. NOTHING so i popped out face plate. I hit the reset button. I unpluged it all and tried again. Same thing. Something is leading me to believe that its on the car side. I just dont know how two completely different decks could have the exact same symptoms. PLEASE HELP!

Everythimg is connected and Ive checked power.connections with a light meter in which they showed to have power, but i am getting NOTHING from my speakers. The deck lights on, I can change source, and even control volume from deck. It just isnt making sound.....
        2. chris busen says:
          when that's happened to me its been because the speakers weren't wired correctly. I'd make sure each speaker is getting a - and + and just to cover all the bases see if your speakers have a preference for where each goes, some do, some don't and check the terminals leaving the radio itself, hopefully that's all your problem is
  2. rodney kelly says:
    i have jvc kd r321 cd radio in my motorhome i would love it work without going through the ignition switch if you could tell me
    1. CarAudioNow says:
      If you take a look at our Aftermarket Car Stereo Wiring Page under our Product & Information Blog Tab, you'll see that there is a "switched ignition power" wire that's red, and a "constant battery power" wire that's yellow. Cut the red wire a few inches from the radio and take the cut wire attached to the radio and tap it into the yellow wire. If you do this, you will have to manually turn the radio on and off whenever you want to use it, and it will no longer turn on and off with the vehicle.
      1. Shey says:
        Hi I have a 2001 bug and I just got a nose stereo. All of the wiring is right and everything is connected but. But when I plug in my stereo it has a VERY dim light in the background, stating that it's on. But it won't officially turn on, when I hit the power button nothing happens. No text,sounds... Anything. I think I don't have enough power. Can you help?
        1. LeAnn says:
          I was having an issue with my stereo not turning on as well like it was getting no power. The original issue was the memory kept resetting every time I turned the truck off. Now I do know about the yellow wire should not be hooked to any constant power but when I disconnected it from the Reds I got nothing. It only worked connected to the reds but erased memory every time shut the truck off. Purely by accident I hit metal w/ the wires & it sparked & blew two fuses. When I got into the fuse panel I notice the fuses were half of what they were supposed to be. They were 7.5 A instead of 15A! And they weren't the only wrong fuses. A lot of them were wrong. (BTW: I didn't do this! Lol probably previous owner) i was about to give up when I found this out & decided to try wiring correctly WITH correct size fuses & all my problems were solved! I have a theory why but most don't believe me so I won't waste time saying. But maybe this will help someone else out?

    I have a jvc kdr300 when I have it hooked up right with constant and accessory when I drive the radio cuts on and off as if its losing power but if I hook both uP to constant it works fine. That is fine for me but alas my wife also drives car and I know she will leave the radio on killing the battery any suggestions? I thought maybe running a line straight from the radio fuse to the accessory wire would that fix it ya think

          I hope we find a solution, I need tunes in my Truck, Will let you know if I get mine cured. David
    2. CarAudioNow says:
      The easiest way to fix it without digging too deep into troubleshooting is to find the closest cigarette lighter and tap into the 12v wire that powers the lighter. If you have a volt meter check which one is positive. It will have right around 12v when you turn the ignition. Use that as the accessory power (red wire on the back of the unit)

      I have a 98 chevy s10 and have a pioneer avh p4100 DVD stereo. When I turn the truck off the stereo stays on. I need help figuring out how to hook it up to the ignition switch.
      1. KD Jones says:
        Remove the remote wire. Mine used to do the same and a car audio tech told me to take it out, it solved the problem.
    4. Garrett says:
      I have opened my fuse box under my feet in my truck, and plugged the power wire into the fuse place, then used the fuse to pinch it back into place, it works as long as it is the radio fuse.
  4. Eddie Lashley says:
    The cigarette lighter is always on, not connected to ignition.
    1. CarAudioNow says:
      Make sure that you're wires are consistent with the list below. If they are correct, you will need to trace back the accessory wire and find another location to tap into the accessory power to bypass the short. Make sure you check all of your adapting wire harnesses for shorts (if you are using any) by shaking the wire. Another place to tap into is from the ignition itself, but again you will need a volt meter to determine which wire is which. 2007 Ford Focus Wiring Colors: Car Radio Battery Constant 12v+ Wire: Yellow/Green Car Radio Accessory Switched 12v+ Wire: Orange/Black Car Radio Ground Wire: Black/Green Car Radio Illumination Wire: Orange/Black Car Stereo Dimmer Wire: N/A Car Stereo Antenna Trigger Wire: N/A Car Stereo Amp Trigger Wire: N/A Car Stereo Amplifier Location: N/A Car Audio Front Speakers Size: N/A Car Audio Front Speakers Location: N/A Left Front Speaker Positive Wire (+): White/Black Left Front Speaker Negative Wire (-): Gray/Black Right Front Speaker Positive Wire (+): White/Red Right Front Speaker Negative Wire (-): Gray/Red Car Audio Rear Speakers Size: N/A Car Audio Rear Speakers Location: N/A Left Rear Speaker Positive Wire (+): White/Green Left Rear Speaker Negative Wire (-): Gray/White Right Rear Speaker Positive Wire (+): White Right Rear Speaker Negative Wire (-): Gray

        Think I might of figured it out gonna try in morning.original radio was around 100 wattts and has a small wire for acc probably 10 or 12 gauge. New radio is 300 Watts so I'm gonna try running a larger gauge. Gonna volt test in morning before I get knee deep in wirering thanks for the help ill let ya know what happens
        1. CarAudioNow says:
          That shouldn't have an effect on the accessory, the accessory wire is essentially just a signal wire. But try it and get back with us either way!

    can I have my dvd screen and my after market stereo in the same power line(cigarette lighter )?
    1. CarAudioNow says:
      The constant power (yellow wire on aftermarket units) should not be ran to the cigarette lighter, however, if you are running two accessories (red wire) off of one cigarette lighter it should not be a problem.

    Hi, I have a 2008 saturn vue and just purchased an aftermarket car stereo. When I hook up all of the right wires, the stereo is off when the car is off but when I turn the car on the stereo stays off. I know there is a problem with the ignition switch wire so I believe I have just not connected those wires. the way that everything is connected right now, the stereo is constantly on. The car stereo itself does not have an on/off option. I installed it last night and since then I have just turned the display off. I am worried that it will drain my battery. I want to be able attach the wire to another one that is controlled by the ignition . My cigarette lighter has power going to it even when the car is off so I don't think that would be an option. Don't know what else to do:S Please help
    1. CarAudioNow says:
      Thank's for the comment, It sounds like you definitely have an accessory (ignition) wire hooked up wrong. See if this helps out at all: 2008 Saturn Vue Stereo Wiring Diagram Car Radio Battery Constant 12v+ Wire: Red/White Car Radio Accessory Switched 12v+ Wire: Dark Green Car Radio Ground Wire: Black/White Car Radio Illumination Wire: N/A Car Stereo Dimmer Wire: Light N/A Car Stereo Antenna Trigger Wire: White Car Stereo Amp Trigger Wire: White Car Stereo Amplifier Location: N/A Car Audio Front Speakers Size: N/A Car Audio Front Speakers Location: N/A Left Front Speaker Positive Wire (+): Tan Left Front Speaker Negative Wire (-): Gray Right Front Speaker Positive Wire (+): Light Green Right Front Speaker Negative Wire (-): Dark Green Car Audio Rear Speakers Size: N/A Car Audio Rear Speakers Location: N/A Left Rear Speaker Positive Wire (+): Brown Left Rear Speaker Negative Wire (-): Yellow Right Rear Speaker Positive Wire (+): Dark Blue Right Rear Speaker Negative Wire (-): Light Blue According to this wiring diagram, you will attach the red wire on the aftermarket car stereo to the green wire on your saturn. The Yellow wire on the car stereo will go to the red/white wire in your car. Let us know if this helps!
  8. Alex says:
    Thanks for responding so quickly!.. I used the exact same wiring diagram for my car when I hooked everything up... I am 99% sure that everything is connected the way you said it should be. Unfortunately I do not have access to my car and the wires at this moment. As soon as I am able to do that I will. If the way the wires are hooked up is not the problem, is it possible that there is another issue and/or solution?
    1. CarAudioNow says:
      The other option you have is to purchase a vehicle specific wiring harness that plugs into your existing wires and adapts them to an aftermarket form, making it easy to wire. The wire harness for your 2008 Saturn Vue is here: http://amzn.to/16znQsu This will make wiring as easy as putting red to red, yellow to yellow, purple to purple, etc. And, it will plug in/out making it easy and clean if you want to remove your aftermarket stereo and put the original back in. Let us know if this helps!

    Amp cutting out after volume is about half way up replaced amp, sterio deck, amp wiring
    1. CarAudioNow says:
      Check voltage, if there isn't enough power it will get put into safety mode. Also the amp should have a light that's blinking in a particular pattern or color that will be described in the manual for what safety mode it is in.
  10. Cory says:
    So I have a 90 chevy lumina and a kenwood KDC-MP345U cd receiver and got a wire harness for it. I wired it and it was all working great until a couple weeks later it fell out of the dash. And I've tried redoing the wires but since then it will not power on at all. Do you have any suggestions? I don't understand what has changed since it fell out if the dash.
    1. CarAudioNow says:
      Check fuses, you might have popped a fuse or two when you rewired it or it fell out.

    I have a sony stereo im trying to put back in my car i have all the wires connected by color but there is a illumination wire i dont know where it goes and when i plug it in theres power to the stereo but it wont do anything any suggestions?
    1. CarAudioNow says:
      Sometimes the illumination feature isn't available on the stereo and is not used, so I wouldn't worry about it. Tape it up and make sure that it isn't exposed. As far as the stereo power, does it light up and function correctly but not emit any sound? Or does it not power up at all.
      1. fred galindo says:
        No power at all,
  14. kathryn says:
    The screen comes on but it wont do anything else-nothing happens when i hit the source button, its one where the face plate slides down to put cds in it wont eject etc.
    1. CarAudioNow says:
      You will need to double check the wires and their corresponding functions. Here's our page of aftermarket wiring colors and functions: http://caraudionow.com/aftermarket-car-stereo-wire-colors/ Make sure that none of the wires/speaker wires are exposed and touching or grounded. If all of the wiring is correct, then the issue might be with your Sony stereo itself.

    I have a 04 mustang GT and I installed a power Acoustic stereo into it yesterday. At first it was playing sound but when i put the unit into the dash the sound cut off and won't come back on. I checked the wires and the fuses and didnt find anything that looked like it would cause the sound to not play. After I read one of the Problem/Solution things above I saw the AMP TURNON thing my car does have that cable but the stereo didn't. Whats my next step. FYI its a PTID-8920B.
    1. CarAudioNow says:
      Double check the PTID-820B wire harness for a blue/white wire. Most head units (if not all) should have that wire coming from the unit. Connect that blue/white wire to the mustang amp turn on cable. If for some odd reason the head unit does not have this wire, just tie the mustang's amp turn on wire to the accessory wire (ignition wire).This will turn the amplifier on whenever you turn the key, just like your head unit. The other problem that you may have, if your Mustang for sure has an amplifier, is the adapting wire harness that you are using. You should be using the Metra 70-5521 with RCAs for the speaker signal wires. Check the harness and make sure you have the correct one.
      1. Amanda says:
        I just installed my after market radio in my 04 Mustang and I got all the wires right and the plugs right. It worked fine then after a while it shut off and started blinking red around the power button. I t took a minute and then finally came back on. Then about 2 songs later it did it again. No power at all. Any advice
      2. Nat says:
        We just installed a new aftermarket stereo and it's working perfect but the back light on the head unit won't turn off. We cut and soldered each wire as we changed the system over but we can't turn the system off... What is going on?
  16. lucas pyle says:
    I'm having a problam with the after market sterio system i installed yesterday. when i turn on my sterio unit my amps arnt coming on with it. Iv gone over the wiring several times and have found its wired correctly. This isn't the first time iv installed this system. i pulled it out of the car i wrecked and just inatalled it in a 2003 dodge intrepid. I'm stumped. I'm lost and couldd really use your advice. Iv never had a problam with this equipment . it worked great. thankyou
    1. CarAudioNow says:
      Double check the amp turn on. It will be the blue/white wire coming out of the back of the stereo. That blue/white wire has to be ran all the way to all of the amplifiers. If it is ran correctly then you'll need to take a volt meter and make sure that there is 12 volts at both the power and amp turn on on the amplifier. Hope it helps

    Hi I have a BMW 320 e90. I took the standard car stereo out and fitted a Phillips motorised DVD/cd player in. I brought the correct wiring harness to fit my car so I could plug it straight in. I had to also run a yellow wire from the harness block to my fuse box for constant power with a in-line fuse, which is part of it... It was all working great and obviously connect up right and also remembering what I was on so memory was also right. So I fitted it all into the car and when I tried to turn it on... Nothing! So I took it all back out checked for a lose wire or a wire that may have come off and checked all the fuses. Everything was still spot on yet its still not turning on. So I tried the standard stereo back in and it works perfectly straight away and the after market still won't. So I tried another head unit just incase and that won't power up either. I tried my Phillips in a friends car and it works straight away. So my after market head unit is not at fault either. I've tested the wires with a multi meter and it seems the red wire (ignition) from the original car loom don't seem to be getting a current from it when touching that and ground. The yellow from the glove box is getting the current as it should... So I'm really stuck now because why is my standard unit working ok yet the after market Philips isn't. even tho its working fine on another car. If there was a problem with any wires surely the original head unit wouldn't be working? and why was the Phillips working ok to start with but now it isn't and its not got a fault as its been tested and its ok... Can anyone HELP I've spent ages on this.
    1. CarAudioNow says:
      I would suggest bypassing the existing accessory wire and finding another 12V accessory source. If there is no power to the accessory wire, the unit will not turn on. Take your meter and try to find another source for the ignition wire that gives a 12V signal only when you turn the car on. You can try the cigarette lighter/charger, or go directly underneath the steering column and start testing some wires. Also, go to www.metraonline.com and type in your car specs and make sure that you did purchase the correct adapting wire harness. There are some vehicles that need an adapter specifically for the accessory wire (GM for example). Some accessory wires do not actually send any voltage, just a faint signal, which is not compatible with aftermarket units. However, if you find another source for the accessory, it should work. Good luck
  18. Jason says:
    Yeah I'd thought about the fag lighter as that goes off when the key does. The only bit I don't get is why it worked when I very 1st wired it up to test it all. Which makes me think maybe a fuse supplying that red wire has blown or something. For it to work then not work something must have stopped it but I don't have a full wiring diagram to look it up propper. It's a BMW 320d 2006 E90. Thanks
    1. CarAudioNow says:
      I would assume it's a fuse as well if that's the case, I know that in some German cars I've found the accessory fuse under the hood instead of in the dash. Have you checked the fuses under the hood as well? If you have access to the manual, look for the list of fuses and locations and check both boxes in both the dash and under the hood.

        I have a 2000 ford f250 and i installed a boss bv8974b yesterday and my sound works but the screen wont come on at random times it will when i turn off the truck and on
  19. Rajohn says:
    I have 2006 maxima with a pioneer radio in it. When the music is playing through all of the speakers, I get major feedback. It sounds like all of the speakers are blown. So I replaced all of the speakers and I'm still having the same problem. But when you turn the balance all the way to the left, the music sounds normal. When you shift the balance to the right, the feedback problem returns. I'm not sure if I should replace the radio or if I have a wiring issue. I thought it was the factory amp so I bypassed it and ran the speakers directly from the radio. What should I do next?

    I just installed a Power Acoustik PTID-8920B in my 2003 Jeep Grand Cherokee and it will take and eject CDs and the touch screen will open and close, but when I open the touch screen nothing appears on the screen. It just stays blank. Where could I have gone wrong?

  23. Scott says:
    I just installed new (front and rear) speakers (kickers) and deck (pioneer ) in my 2000 KIA Sephia LS. I hooked the speakers up before the deck, and they were working fine with the factory stereo. Now that I have installed the new deck the speakers are distorted. It sounds like the person is far away and there is not any bass really. Now I had to figure out the wiring colors since KIA likes to make their wires different colors than even their manual or diagram has they are. I looked at the KIA harness and the colors of the wires and mix matched what I thought was the right colors together, but obviously I didn't get it 100% correct. Now KIA has a grounding wire in their harness AND they had one on a post behind. I just ran the grounding to the actual grounding wire instead of in the harness and just left the harness one unused. Q1: Is that okay? I hooked the blue & white wire from the new harness to the Antenna of the KIA wire. Q2: Is that right and/or okay? The only other wire I have unused is the dimmer wire and I've read that's okay, so I'm not too worried about that. My last question would be Q3: Could I have either switched the + & - wires up for the speakers, or maybe switched the F & R wires? Or both? Any help would be greatly appreciated! Thank You for your time! Scott

      First thing, I would double check whether your car has an OEM amplifier or not. If it does, it will explain the distortion that you are hearing and you will need a different wire harness that will adapt the RCA outputs of the aftermarket head unit to the stock amplifier speaker signal wires. Or, bypass the amplifier all together. To answer your other questions, as long as the ground wire is attached to ground, it is fine. The Blue/White wire is supposed to be an "Amp Turn-on", if there is a solid blue wire (coming from the aftermarket head unit), use that as the Power Antenna wire. If you don't have a blue, then either the accessory (red) or the Blue/White wire will do. But, if your car does come stock with an amplifier, make sure that the Blue/White wire is connected to the corresponding amp turnon wire of the car.

        Thank you very much for your help in this matter. I believe that everything is connected right now. Sounds a whole lot better now! Thanks again!

    I bought a Dual XDMA460 aftermarket stereo to go in my 2008 Chevy Malibu also bought a gm adapter harness to do the wiring 08 also now when I plug all matching colors together nothing happens also has two orange wires that did not go with any wire on the stereo. But when I plug the red and yellow stereo works but no volume, and also locks my car system so if you could please help with these corrections and the yellow and red because I'm sure that's not right. Thanks
    1. CarAudioNow says:
      The orange wires are typically for illumination and dimmer. Sometime the head unit doesn't have the features to support those two wires (solid orange and an orange/white) so disregard those. As far as no volume, your car must have an OEM amplifier, make sure you check the blue/white wire to make sure it is hooked up to the corresponding amp turn on wire on your Malibu. If that doesn't work, double check the compatibility of the wire harness you purchased with the features of your car. www.metraonline.com might be a good place to start (type in your vehicle specifics). Sometimes you need a special harness for GMC and Chevrolets that are OnStar enabled, have Bose systems, and etc.

    installed aftermarket radio in 2001 ford focus, while idling works fine go to drive it flashes, get to 30mph is fine, then when i come to a stop it will flash and shut off, then flash until i hit about 30 again then will be fine.....
    1. CarAudioNow says:
      Did you purchase an adapting wire harness? Double check that your accessory and constant (Red and Yellow) wires are both connected to the corresponding 12V accessory and 12V constant wires of your car.

    Hi I have an 03 chevy tahoe and I just installed a jvc in dash. The problem I'm having is when I turn the car in I get no power to the unit except for the cd eject button. All wires according to spec are in correct configuration, could you point me in the right direction ??
    1. CarAudioNow says:
      If you have a volt meter, make sure the red accessory and yellow constant wires have 12V. The accessory should only have 12V when you turn the car on. Constant should have 12V all the time. If that's not the issue, it may be the unit itself.

    got a problem that has been ongoing for a year now ill tell u the story.................... I bought a 2011 Hyundai i30 brand new then brought it to a shop to have custom install including having old stereo cut out to fit a new one and first install was pioneer AVH-X8550BT /JL audio 6in splits front / JL audio 6in coax rear / 2x JL audio 12in subs with US audio bezerk 4channle75w per channel and 1000w mono block and new wiring............................ first problem arose fairly quickly the av unit kept melting fusing the buttons on the face of the unit the touch screen still worked and remote still worked as well the av unit was replaced by the shop but sure enough the second one melted as well so they replaced it again with no one being able to find any power faults or even faults with the product ....................when the third one melted the store said they want to try a different av unit to see if it would happen again so I agreed and they installed Sony XAV701BT av unit and for some strange reason there was no problem with the av unit since but instead speakers have been blowing constantly including the subs the car has been rewired twice and amps have been checked but no faults have been found . they now want me to replace the amps but yea I am not confident that I could fix the problem........ I am reaching out hoping some one may have any idea what could be causing all this.... I am technically minded and have certificates in electronics and IT but its got me boggled as with all installers involved cheers for any help anyone can provide

    I am installing a dash unit and speakers in a 99 jeep Cherokee sport, I have power and sound but the sound is weak and "hollow" Anything come to mind ?
    1. CarAudioNow says:
      Find the head unit's equalizer settings and switch through the presets to see if one is better than the other. If you can't find one that sounds good, the unit should have a setting to adjust the equalizer itself, you can change the eq or have a professional tune it to your car. Reference your unit's manual to find the settings

    Hi i hope You can help me. lately i have bought new aftermarket radio, speakers and subwoofer and i have Been struggling with a problem and hope you can help me. well here it is: my speakers don't work and my subwoofer only a little bit. but sometimes after the car has been running a little while i reattach the headunit and everything works fine but after some time it stops again. some people said that the speakers inside the door touched the metal of my car but they don't before this happened everytime i was driving over a bump and my sub would make a random whoof kind of sound i hope you can help me with my problem and thank you for your time
    1. CarAudioNow says:
      Sounds like a wiring issue/short. Check the wires behind the radio and make sure all of the connections are good and correct and that no wire is exposed. If you did it yourself, double check the function of the wires on the 'vehicle-side' and that it matches with the correct wire on the 'head unit side'. For the speakers, make sure that the blue/white wire is connected to the correct amp turn-on wire (if your car has a built-in amplifier from the factory). Hope this helps.
    2. David says:
      I have a similar problem. I had subwoofer and after market radio installed from an car audio shop. It has been working fine for about 2 or 3 years until recently. Every time I drive over a bump or a dip, my power antenna shuts off and my subwoofer shuts off along with it; leaving just my radio and speakers still playing. But, after I go over another bump the antenna and subwoofer turn back on. Thus, they pretty much turn on and off randomly. I think the problem may be contributed to roads that I drive in New Orleans that are full of bumps and are rough. I checked the appropriate fuses to make sure none were blown out but they seem to be all intact. I can't try to fix the problem myself because I have don't have access to any tools. I am planning to take my car to a repair shop. What could be a possible reason that my antenna is not working so I can give the mechanics a better insight on what the problem could be? Why is that only my antenna and subwoofer/amp turn on and off?
  31. lucas says:
    i have an 01 jeep cherokee and im having trouble with my kenwood aftermarket itll play the radio threw the back speakers and the sub but when i switch threw the other options it just plays threw the sub what could the issue be ive asked both my friends who deal with this kind of stuff all the time but even they dont have a clue.
    1. CarAudioNow says:
      Could be a wiring problem. Sounds like you may have wired the powered antenna (solid blue) to the OEM speaker amplifier (if you have one). Make sure that the amp turn on wire (Blue/White) is wired to the internal OEM amplifier that the car came with (again if your Jeep has one). If that's not the issue, you may have an faulty kenwood stereo.

    We have a 2010 Pleasure-Way RV built on a Ford E-350 chassis with the Triton V-10 engine. The chassis is actually a 2008. Very happy with the combination and the AM/FM w/CD player is the standard Ford unit. At times the CDs get so hot while playing that they won't continue and sometimes won't eject the CD for some time. After discussing with friends, I was told that the audio units (whether Ford or otherwise or even for autos) used to have a small fan for cooling purposes but this has been deleted on the units being built. Any information or advise will be appreciated.

    Hey! : ) The flashing advertisement/mode options that play on my stereo screen when it's waking up just plays and plays and when I hit the mode button to switch from aux to radio, etc. it does not respond. The CD player works but nothing else registers to my botton-pressing. It just flashes things like FM*Aux*CD player*Tuner* and doesn't ever stop. It didn't used to do this. - Any thoughts?

      There's a demo mode for receivers that you can turn on and off in the settings. If you are able to, click on the options/settings button and go to the display settings and turn off the demo mode.

  35. Kurt says:
    Installing a Pyle PLDVN78 in a 2006 Acura MDX. I'm using a Scosche wiring harness adapter to connect to the factory wiring. Everything powers up and works great until I turn the car or accessory off. When I turn the switch back on, the stereo will not come back on. In order for the stereo to come back on is to either hit the reset button on the front of the stereo OR unplug the harness and plug back in. From there powers up and works great until the you turn the switch off. I've measured the constant power and accessory power; all is 12v. I've tried running the accessory power to another 12v source and still no change. At this point, I don't know if the factory anti-theft/wiring is causing the problem OR if this issue is within the stereo. Any help would be appreciated!

    1. CarAudioNow says:
      Double check that the accessory wire (red wire) is showing 0 volts when the car is off, and ~12 volts when the car is turned on or the key is in the accessory position. You may have wired it the accessory wire incorrectly.

    Just got subwoofer and amplifier installed. every once in a while the subwoofer will cut out and the red light on the amp will illuminate. If i take out the fuse coming from the battery and put it back in it starts to work again. Anybody know how to fix this? Any help is appreciated. Thanks
    1. CarAudioNow says:
      Depending on the amp, the red light (and the sequence of flashing) will determine what the problem is. e.g. solid red could stand for low voltage, solid blinking could stand for a short, 2 fast blinks, etc. If you can, check the amplifier's troubleshooting section of the manual and it will tell you what the problem is.

    Hello, we recently installed a aftermarket Pyle touchscreen stereo to my car, previously had an aftermarket installed professionally and everything worked beautifully, but decided to install the second one ourselves, everything works except the subwoofer, could it be connector problem ? the plug in wrong plug hole ? everything was left exactly as was settings on amp as previous system, does this need to be changed ? thank you for any help
    1. CarAudioNow says:
      If the amplifier turns on, it could be a signal issue and the RCA wires may not be connected properly. Check that the RCA wires are connected to the SUB or S/W output of the head unit, and that the RCAs are connected properly at the amplifier. If the amplifier does not turn on, double check the amp turn on wire (blue/white) is connected properly at the back of the head unit and harness, as well as on the amplifier it self. Also check the amp fuses, and the in-line fuse that will be located somewhere along the power wire to the amplifier to make sure that nothing was blown.

    I have a 2006 bmw z4 i went to a professional installation shop to have a new after market radio installed along with a new amp (it was a pioneer radio). I bought the correct wire harness and all. Once installed a few days later after driving the car and hearing music my speakers will sound like they are popping or staticky. Also when i speed up it will happen more frequently. BUT, when i turn off my car and turn my key too ACC (Option before turning on your car on the ignition) MY RADIO PLAYS WILL NO EFFECTS! JUST HOW IT SHOULD PLAY. I took it to the shop and after two hours they said it was the radio was defective. So i sent the radio back and amp(just to be sure) and a new wire harness and bought another new aftermarket radio and another new amp. this time it was a JENSEN touch screen aftermarket radio. So i took it back to the shop and they installed it. two days later with a new aftermarket radio of another brand, a new amp, new wire harness I am back to square one. Same thing is happening popping speakers on one side if not the other side but I turn my car off and put the key on the ignition to ACC and the radio is playing PERFECT. What could be wrong? help please
  45. Jarv says:
    I installed an active Fusion subwoofer (CS-AT11) in my car yesterday (first time doing it) and I'm pretty sure I did it all correctly. It all seems to work well until it drops out, then back in every now and then. It seems mostly random, but happens -when I turn the headlights on, then off -sometimes when I turn the aircon on -sometimes when it's bumpy (though this may just be random, plus i haven't stuck it down yet) The sub doesn't actually turn off either, it's volume just decreases to near nothing. The time it takes to come back on is random too, but usually no more than a few minutes Any clue what may be causing this? Bad earthing? Bad battery?
    1. Theo says:
      Probly should check for a bad ground or call your local install shop for tips like soldering all your connects and to scrape paint around ground points and to avoid areas that have moisture or can spark. The best way is to get a good installer to check your work or at least pull on the connect and make sure the ground doesnt move and get a 1farad capacitor to solve battery problems if any. $58 walmart

    I've had this system in the car for a while. However it has just cut out and ever since the amp is showing warning light. I have checked all the connections and even changed the amp and the same story again. Reading through different blogs I found one comment that said to check with power meter the ground and remote wire. Once I have done that, it looks like amp has been rebooted and it had the green light on and was working perfectly. However it has cut out again, and I done the same trick again but it never came back on. Please help..

  56. Mike Dempsey says:
    I have a 2000 jeep grand cherokee laredo with the infinity gold system. I removed the stock head unit and replaced it with a new kenwood kdc-bt558u. I purchased the metra wiring harness for it. After installation, everything works but the audio. I can adjust all of the settings. The siriusxm works fine, the steering wheel adapter works fine. It holds all of the memory; but I have no sound. I looked in the trouble shooting section and found that I can actually turn the speakers off or set which size of speakers are being used or there is even a setting for OEM for optimal use. When I removed the original head unit, there were only 4 connections: 1. Steering wheel control 2. Ground 3 and 4. Wiring harnesses I have read some of the suggestions on here and found the blue/white amp turn on wire to be a very logical suggestion, however the ONLY wire coming out of the aftermarket head unit is the wire for the microphone for the bluetooth phone option. It does have the infinity amp; and prior to removing the stock unit (like 30 seconds prior) everything worked fine as far as getting sound out of my speakers; and now nothing. I am positive that the speaker wires are hooked up properly between wiring harnesses. In effect the only change is the head unit and nothing else has been bothered so I am fairly stumped as to what it could be if the settings on the new head unit are turned on for OEM speakers and there is no wire coming from the new head unit to connect to the amp turn on. Any help would be appreciated. It's way too quiet in my car! Lol

    I have a old Suzuki car in India and I recently bought a car FM radio, it has a YELLOW & RED wire. From the forum post it is clear that YELLOW wire to be connected to "constant battery power" and RED wire to "switched ignition power". My car have a only one connection which turns ON (+12V) when car key is turned to AUX /ON position, there in no power when the key is in OFF position. The power is also ON with the engine running ( the key is at ON position). Please advise how I connect the RED & YELLOW wire. There is no amplifier in my car, so should I leave the "blue & White wire" unconnected? Should I connect the antenna wire to body of the unit?

      Hello all! I stumbled upon this site while searching the open web for an OEM stereo for my 93 Geo tracker. After reading several of these posts it is clear to me that many of them are related problems. I was an ASE certified electrical mechanic for many years and can tell you from experience that a lot of the after market audio systems don't have very good directions or diagrams for the do it yourself-er. Many newer cars do not have good chassis to frame ground, that means when you have lights dimming and so forth you should run your ground wire directly to the NEG side of your battery, make sure the terminals are both clean and tight, should not be able to twist terminal off battery post by hand but don't over tighten or will crack post inside, a little "DI-electric" grease will help keep terminal and post clean, this is called a direct ground and is always required with "high power" amps and audio equipment. New systems sometimes come with anti theft built-in, this means other than the first plug in for testing the system will not work without the owner code being input, then it should work until unplugged again at which time the unit will re-set and require the code again to activate. Many OEM units require that a dealer program the unit to the vehicle, to many to list, but check with your local dealer for advice on this. If your vehicle is a "uni-body" look for a copper ground strap going from chassis to frame and make sure both ends are CLEAN and tight. Hope these things help some of you and happy listening; Crank up the tunes!!

    I just installed a Kenwood detachable face stereo in my niece's Toyota Echo. We turned the ignition on and the stereo just turned on with the igniton. The display does not work at all. It will play cd's and the volume works intermittently and so do the track select buttons but the display stays blank through out. The volume and track select buttons will work at first then stop working but if you turn the ignition off then back on they might work again. You might have to try cycling power like that two or three times untill that stuff works again. There is a blue ring around the volume knob and all the buttons light up on the faceplate but the display stays blank. The power button doesn't even control the stereo. It just turns on and off with the car's ignition. Hope you can help! Thanks

    I have a 2003 Chevy Trailblazer that the previous owner had spliced wires and installed a after-market radio. We attempted to remove and install a new Head Unit using the same wire scheme and looking up what colors go to what after-market wires. I do not have on star. I am not getting power. Here is the colors i have: Black Black with solid white line Orange (1) Orange (2) Brown with solid white line Tan Yellow Lt Gray Tan Lt Green Dark Green Lt Blue Blue I know what the colors are for outside of the two orange wires. I am not 100% sure on which is Constant and which is the switch/ignition. I am also not sure of the free wires (untapped) Black with solid white line and Brown with solid white line... I have all other wires together that i can verify thru Chevy Wiring color Codes (some not listed) and the pioneer wiring color code.. I dont have power either thru constant or switch/ignition..is it as simple as switching the two orange wires with the yellow and red of the head unit..Again i have no power..i cant turn on the HU and it will not turn on at start of vehicle. I checked all fuses.. Please help

      Many of the older Chevys didn't have a 12v accessory wire, which tells the unit when to turn on and off. An adapter (Metra GMOS-01) was needed to take the low voltage factory signal wire and convert it to a 12v that is compatible with aftermarket units. To test this, you'll need a voltage meter to test the accessory wire and constant wire. Both should be 12v when the key is in the ignition and turned to the 'on' position.
      1. Frustrated_dad says:
        with the wires spliced how do i go about this
      2. Frustrated_dad says:
        also the 2nd connector has been disconnected and those wires capped..so again i dont have much to work with and dont know what to do..
  76. Frustrated_dad says:
    I guess my next question would be if i bought this interface which i have found cheaply will then need to undo the spliced wires and then wire the After-market HU to the interface and cap them wires then do the same from the factory wiring to the interface..will the colors be similar or will i need to map out the colors again..i figure the two orange wires didnt matter since they are similar..just rather they are hooked to the constant or ignition
  77. sonya says:
    2007 VW jetta--had an aftermarket radio/handsfree/dvd/touchscreen radio installed and it is pulling power from alternator causing a dead battery. Radio has to be turned on an off also. Is it hooked up incorrectly. Radio should not have to be turned off when you get out and it should not be pulling so much from the alternator that it kills the battery. Also the radio seems to turn itself on when no one is in the car!! HELP!! Is there some type of harness adapter that connects the old harness to the new one so it will pull power just like the old radio??

    I am doing an install on a motorbike. You seem to be the most knowledgeable and proactive on the planet:)! Question; is it a must to hook up the red accessories wire? I would like to run this completely manually. Also, there is a wire for "illumination" in orange/white. I am not sure what that means and again, does it need to be connected. if so, is it a 12 volt needed? thanks in advance!

    Hi, I have a 2001 Tahoe LT w/o bose but with factory sub and onstar. I bought an aftermarket headunit and I have everything hooked up and all of my connections seem to be correct which I've tested repeatedly with a MultiMeter but when I put my vehicle in drive the headunit cuts out and flickers off and on in real quick intervals with no sound or anything just quick flashes of light, but while in park It stays on and i get perfect sound from all speakers. I have checked the constant and I'm getting 12.4 to 12.5 volts driving and not driving. I've checked my alternator also but it also is working properly at about 13.2volt range. Also this is a manual wiring job given that the factory connector was missing. Any help would be much appreciated :)

    I had a alternator go out on my 2007 Chevy Silverado WT, with NO OnStar. After replacing the alternator the stereo will not come back on, I removed the head unit from the dash and disconnected the wires and then turned the accessory on and wired it back up and it work, but after turning the ignition off and then back on again it wont come back on. Anybody have any ideas?

    Please help. I installed a Sony radio in my 2001 Honda Civic and for some reason the buttons/volume knob only work about 50% of the time. Sometimes the buttons will work and not the volume knob, sometimes nothing will work, sometimes everything will work. Is this a radio malfunction or am I doing something wrong?

    I have a pioneer Bluetooth head unit wired into my 95 Subaru Legacy. Every time I turn on my car I have to set up the clock, turn demo mode off. But it does remember my phone in the Bluetooth settings. I have to reconfigure my subwoofer settings every time also. I thought it would be a wiring issue but I have the yellow wire running to the yellow wire and the red wire running to the blue/red wire.

    I have installed a clarion head unit, front & rear speakers & twin subs in my 99 Holden rodeo dualcab. I used all the factory wiring for acc, constant 12v, earth & front speakers but ran my own wires for rear speakers (didn't have factory rears). Front speakers work fine so do subs but r/h rear speaker doesn't work & l/h rear half work (sounds very echoey)

    Just hooked up a new head unit and every works great. I have an amp and a sub hooked to it and it sounds great. The only problem I am having is when initially turn on the unit it has very little high range sound. When I push the treble up or down button or even the bass up and down button everything goes back to normal. It also does the same thing if I switch between application on my touch screen. I believe everything is wired correctly. Ever heard of this?
  90. Colter says:
    i have a 2005 Chevy Equinox and just installed an aftermarket touchscreen stereo, I purchased a new wiring harness that allows me to use the existing wiring without looking for an alternate 12v source. After installing the stereo seemed to work fine but the next day it only turns on some of the time when starting the vehicle and sometimes it won't turn on until I turn the ignition off? I checked the wires and nothing seems to be lose. Any help would be appreciated.

  92. Amar says:
    First time trying to install a stereo unit and thought it was successful until I tried to listen to music. I have power to my stereo but no sound from radio or aux input whatsoever. I have a 2000 toyota avalon which has the jbl system in it. I already knew I could bypass the amp but I wanted to keep my tweeters working and whatnot. I bought a wiring harness so I wouldn't have to bypass my stock unit. Then the stereo unit also came with the power supply harness and the speaker harness. In short I did not actually touch my stick wiring. I plugged the stock connector into the aftermarket one I purchased then did on the wiring from that one to my stereos harnesses. Now the aftermarket harness had rca plugs instead of just speaker wires. I clipped those off and just matched all the wiring. After all the wiring is done I have one wire exposed from the head units harness that it came with which is the power antenna. Then the aftermarket harness has the amp on wire exposed and the power antenna wire exposed. My wiring for my speakers them selves could be backwards but I just want to make sure before I go messing with it that it isn't any simpler. I connected the amp on wire to the power antenna and got a pop noise while trying to see if it would play aux music. No response from connecting power ant to power ant wire though. My question is should any of those wires be hooked up to something or is it just my speaker wiring that could be wrong?
  93. PM says:
    Having a strange problem with a Sony MEX-BT3800 head unit. It was removed from my old car and moved to my new car, an 06 Sorrento which uses a GM wiring harness. The factory radio was a Delco. I made up the harness and no issues. The radio works but the USB port and Bluetooth both show that they are working but there is no sound. AM/FM radio works fine and has sound. I've tried resetting the radio, redoing the Bluetooth, tried different Bluetooth phones, to no avail. I even have a second of these Sony radios and swapped it in but the same result. I am starting to wonder about the wiring harness. Is there anything that can cause this? I do know in the old car I didn't connect the Amp+ lead but I did this time. Could that one wire do this? Thanks!

    I have a 1985 Cadillac Fleetwood and it had the cassette deck stereo. I bought a install kit and when I plug into the factory harnesses the new stereo will turn on and I get sound from left side F&R only absolutely nothing from right side. Install guide said that the orange wire from factory is the constant. Hiwever, there are 1 orange and 2 orange with black stripe from right side of old stereo. I tapped into the orange just as the illustration said and I get power but no memory and no right channel and I know the speakers work as I plugged old one back in and it works as intended. Please help!!

  96. brad says:
    Recently bought used 2003 dodge ram 1500 and it had aftermarket radio and amp in it. Everything seemed to work fine and my mechanic told me that the radio would sometimes come on by itself with no turn of the key when he was working on it. Wanted to disconnect and take amp out so I disconnected the amp from the battery and then disconnected the stereo wires from the amp (no speakers were hooked up to the amp). Now when the car is completely off the headlights, interior lights, remote keyless entry, and steering wheel lock do not work but when I turn the key everything works fine. After reading these post , it seems the previous owner may have hooked the radio up to a constant hot and somehow tied it into the interior lights, headlights, and possibly ignition switch. when i disconnected the amp, there was a little blue wire that was hooked up to a terminal on the amp right next to positive terminal. Do not know if this blue wire means anything but it might. Any advice would be awesome.

Ever since the guy installed it, my factory lcd either turns off for a day or two, or reboots and i have to set it back to what kind of car it is in the miscellaneous menu. Does the lcd and stereo need seperate power or something? I am dumb to this and cant seem to get help from the installer either.

    I purchase 2 headrest dvd players for my 2013 Dodge Charger, everything works FINE, beside the fact that I can still turn them while the car is completely off, I went to AutoZone and bought the "ADD A FUSE" component n combine it with the radio fuse located in my trunk fuse box, and although the radio turns completely off when the car is off the headrest dvd players doesn't, I was wondering is there any other way I can run my power wire so that the headrest dvd players will completely shut off when the car is off????

    I just bought a new aftermarket radio, it won't work. I checked the wiring twice I did everything it said. Yes I unhooked the negative on the battery also. I redid the wiring twice but it still isn't getting any power. The kit came with a long red wire that says 12 volt ignition switched on it but has no place to plug it in. I own a 2004 chevy Colorado. I also even returned one radio and got another.
    1. CarAudioNow says:
      Many of the Chevrolet and GMCs that are equipped with OnStar don't have a 12v ignition wire that is compatible with aftermarket stereos. It is a data signal wire instead, and requires an adapter - The Metra GMOS-01 (If your truck DOES NOT have a factory amplifier) or the Metra GMOS-014 if your truck DOES HAVE a factory amplifier. Hope this helps.

    I installed a Clarion NX602 double din head unit in my 2006 GMC Envoy Denali. I also installed a Kenwood KAC-7202 amplifier and 2 12" Dual subwoofers. Now, when I turn the radio up past a certain point, the music will cut out and stay out until I power it off then back on but the subwoofer still works. I still have stock speakers in the door and am still 'up in the air' on whether or not I am going to upgrade. If you could shed some light on what may be wrong that'd be great.

    HI I bought a new stereo and installed it, everything works fine except I can't for the life of me get the faceplate to stay on. It clicks into place on one side and just hangs on the other side, which is the side that needs to stay in place for the whole thing to work , how do I fix this?

    Hi guys. I am having a really weird problem. I own a Dodge Stratus. 2005. I just took out the old stock system and bought the car specific wiring harness. I wired it all up according to color codes but when I got done I started my car and then it died after 2 seconds when my stereo turned on. Also none of my guages will work when it fires and the odometer says no bus. I can get my car to run just fine if I unplug the radio harness. It has something to do with my radio and I cannot figure out what it is. Help me please? Its an Eclipse radio.

    Hi Guy's, I am in the middle of a nightmare! I hope this has not been answered and I missed it? I have a 2012 Honda Civic SI Premium sound System with Navigation and I want to keep the Head unit with the Nav. I bought an Audio Control DQ-61, 2 JL Slash Amps, 2 JL 10's in a sealed box a set of JL 6.5 Components up front and ID Chameleons in the rear. With all the right stuff I thought this system would sound at least decent, but nope sounds like S... Then I really start researching my car and found that the DQ-61 was being fed by that horrible Amp connected to the deck, So I find a Metra Plug 70-1728 to Bypass the amp. But then I find out that the plug will bypass the amp and connect to an AFTERMAEKET DECK. Some times I just want to bury my head in the sand and give up, but even under sand I am sure I could still hear if not feel someone's awesome BASS LOL. Does anyone make a plug for the output of my NAV/STEREO so I can Bypass the Factory AMP and wire into my DQ-61 and that my Factory Deck puts out enough power for the DQ-61 to work? Thanks K C Neil................

      You may be able to tap into the signal wire for the oem amp to use as the input to your sq-61 depending on the voltage of the signal wire. Here's a wiring diagram for a 2012 civic that might help. http://www.9thgencivic.com/forum/audio-video-navigation/3737-audio-wiring-diagrams-2.html
      1. Kenneth C Neil says:
        Hi, thanks for the response. You said here is a wiring diagram, but I did not get it or were/how to Access it? Currently the DQ-61 is getting it's signal from the OEM/HONDA AMP then when it is connected to this it is Summed internally by the DQ-61. The big problem I need to solve is to get the signal from the Factory Radio directly to the DQ-61 or as it is now it's Garbage in Garbage out! The OEM is the culprit but how do I pass it??

    I have a 2010 Sport. I recently added my old amp and sub to it so I can have better sound. I also have an aftermarket JVC deck that I have had it since summer when I bought my Yota. When installing the amp and sub the direction said to connect the blue wire from the sub to the remote wire in the wiring harness for the deck. When researching what color this wire was it said my vehicle doesn't have this wire. Is this true? I have it connected to my ignition wire instead which worked for the first two hours but after that my deck display has dimmed and won't turn on.

    Installed a new Pioneer DEH-x6700BT on an 06 Altima w/ Plastic mounting kit. Problem #1 is the poor radio reception for regular radio stations. Buying an aftermarket antenna since stock is a windshield antenna. Problem #2 is the significant drop of highs overall. Highs sound weaker than factory stereo. All car speakers are connected well. No EQ setting will fix this. Stuck with this problem. Advise?

    I have a 1995 Lexus SC400, and I bought the car used, it had 2 previous owners. but it looks as if the Previous Owner(s) tried to do their own custom sound install. I wanted to re-do the sound system. I ran all new wires for each of the speakers and bought a FH-X721BT Pioneer Double din receiver. I had Best buy geek squad install it. It works and run except, when I press the receiver firmly or press a button hard on the receiver it resets... It will still have my custom lighting lit up but the song that I was playing will stop playing, then it will pick up where it left off 3 seconds later. Almost like the machine is resetting its self. but it does the "resetting" randomly when I drive too. For the most part everything works fine... It is very annoying when im singing a song and the machine turns off "resetting" for like 3-5 seconds, then comes back on

    Hello, I just installed a Sony MEX-BT3800U deck in my 2003 Honda civic. As soon as I installed it, it worked fine. I was able to turn up the sound, changed inputs, every thing was functional. I then paired my iPhone 6 with the blutooth and now it is not functional. To turn on the stereo I need to press the eject button and do the same to change the sources. I cannot change songs when the cd I had in there is playing, I cannot eject the CD, and The volume is stuck at one level. Now the person who installed it just used the wiring harness that was already on the stereo. Do you think changing it to the Honda wiring harness will make a difference?

    Hey ya'll I just got a 2005 civic lx. I put my pioneer in with my one sub and amp. I used them in my 05 elantra and they sounded great. Everything works (i think) except that the radio doesn't have any sound. It seems that it isn't picking up reception. I checked the wiring and the antenna plug-in. Any ideas???
  174. JJ says:
    "Problem: Head Unit has Power but no Sound Possible Solution: – Many cars have built in amplifiers that require a 12v signal to be sent in order to turn on the Amplifier, most common being Bose, Infinity, and JBL. If your car has any of these systems, check your AMP TURNON signal wire for 12v. Blue/White wire located on Head Unite wire harness." Where is the solution ? What do i do when there is no power in the AMP TURNON signal wire ?
  175. soroush says:
    I'm trying to connect an aftermarket (sony N5000BT) to my 2006 Hyundai tucson, My problem started when I realized that I have blue/white wire on the Sony harness and by the book it should connect to the AMP or POWER ANTENNA but, on the other side (Metra 70-7301) wiring harness gives me two seperate wire, one is blue (power antenna) and the other one ic blue and white (amp). Know I'm confused, as I know my car has a factory amp so I have to connect the blue and white from the HU to the harness. The question remain is: where should I connect the blue wire which comes out from the wiring harness (Power Antenna Wire)???

    Hello, I'm having an issue with my car stereo. What's been happening is whether I'm parked or driving, with or without the engine running, I've turned the stereo on and anywhere from 5 to 30 seconds the stereo will shut off. There are rare occasions that it stays on for about an hour or so. Then there are other times where the stereo doesn't turn on at all. When turning on the fog lights or headlights, the stereo will light up but still will either not turn on or shut off soon thereafter. Can you please help with this?

    97 Saturn sl2 just installed a pioneer Bluetooth deck. But when my car is still running it powers off when I open the driver side door. Also my dashboard lights and tail lights quit working. The first time they quit it was a fuse. But this time the fuses are good still. I used a multimeter to find the right wires. The one I originally found to be illumination was no longer giving a reading and a wire that wasn't being used by the factory radio read for 12v when the ignition was on. Couldn't find antenna +/- though

  196. Richard Cantrell says:
    Had a kenwood double din installed in a shop with amps and speakers and everything worked great for a couple of months. Then one day the unit turned off for a few seconds and then turned back on and worked great. Over the next couple of months the random turning off of the head unit became more frequent and stayed off for longer periods of time. Now I'm lucky if it turns on once every other month for a few seconds. I have noticed that it seems to turn off at completely random times. It turns off when accelerating, decelerating, sitting in driveway, car started, car turned to aux power, when its hot, when its cold, the only pattern I have noticed is the fact that it got worse and worse. I haven't even been able to find anyone that has posted a similar problem to mine so if you are a kind person and you want to get into heaven, please help me. I'm desperate. My head unit is only 6 mo. to a year old and sounds great on the rare time that it is on.

    Hey, I just installed a car stereo. I have all the wires hooked up correctly, but it has no power. I decided to hook up both the red and yellow wires together (ignition and constant) and i get power, but can't turn the radio off. I have tried all different variations of connecting these wires together (2 reds one yellow, 2 yellows one red, 2 Yellows other red) but it only works when they are all connected, and it won't turn off until I disconnect the wires. can't seem to figure this one out. Any ideas?

My problem is that it's starts to off the sound but the power is still on and everything else works normal but no sound. It'd be playing , hear some static and sound would shut off. I turn off head unit for a little while and turn it back on and sometimes there will be sound, sometimes not. All the wiring is tightly connected.

    I bought a Jensen in dash gps unit and a back up camera to go with it. I had a professional install. 9 hours later, the installer tells me there is a problem with the equipment. The back up camera is wired, and there is display when the key is in accessory mode, but as soon as I turn the car on, it says "no signal". The car is a manual and yes it is in reverse, I am just trying to figure what I need to do to try and get it fixed. The installer says there is something wrong with the stereo unit. Anyone heard of this?

Any advise? Thank you.

    Hoping someone can help me. I bought an after market car stereo to put in my daughters 1997 plymouth breeze. we removed the factory installed radio and connected everything to the new stereo and it worked beautifully. we then unhooked the new stereo to get ready to mount everything and put butt connectors or caps on the wires and now it won't come on. We unhooked everything, try another brand new stereo the same way and nothing. We unhooked that and put the factory stereo back in and nothing. We checked all the fuses and everything there is good so i have no idea what to do next. please help! any ideas are truly appreciated.

    I have a 2004 Hyundai Elantra, with an after market sound system that is Tuner/CD player/AUX capable. The CD player and AUX cords work great - however, the Tuner does not. When I press the button for Tuner - there is no sound - not even radio static. The different channels show up on the display like they should, but the audio is just not there. I can't tell if it's an issue with the wiring or if the antenna is damaged.

My prolem is that the speakers are making a boom when i change de melody or chenge from cd to radio or turn on/of the HU. I tried tu change the HU, but the problem persist. I tried to change the amplifier and the problem is steel there. It can be a problem with signal wires? These aren't shielded like an OEM electrical harness, i just roteted between the... The ground is ok, i used the power cables from the older amplifier(OEM with rear amplified). Do you have any sugestions or solutions? Many thanks in advance! Kind regards!

    I have a 1993 Subaru Impreza with original Speakers and original Kenwood subaru cassette FKR-X55 stereo (dont know if that helps) . It works like powers on it shows the clock and the buttons work but it wont play any radio stations even though it picks up the channels when automatically searching or when you put in a cassette it will eject it 5 seconds later aswell as its Kenwood Cd changer , so i dunno it might be just a lost cause and need a new one or if one of the wires are wrong some how or its not getting its full 12volts or what ever it takes , reply as soon as you can it will help alot . Cheers!
