Common Car Stereo Problems and Symptoms

Aftermarket stereos can be a pain if they aren’t functioning properly. Whether it’s installation that might not have gone as planned, or a random problem that comes out of nowhere. 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.

    Hi there,

    I installed a new alpine h/u and it work fined but for some reason now it’s blowing my fuse located on my yellow wire on the h/u power harness.

    I unplug everything that I think could be causing a short (when the harness is not plug into the h/u the fuse don’t blow) but even with the keys in the off position, the minute I try plug in the harness into the h/u “BOOM” the fuse on the yellow wire blows.

    Anyone with any suggestion on how to troubleshoot and prevent this from happening?????????

    1. Mark Kelber says : Reply

      Did you replace the factory head unit with the Alpine or was there another aftermarket previous to the Alpine? If you replaced the factory radio did you use also a harness that plugs into the harness you unplugged from the OEM radio to facilitate the installation of the Alpine? You didn’t mention what year, make, model you had or any of the parts you used so there is little anyone can help you with without that information. Sounds like you either have the wrong harness because the yellow wire is constant B+ and it sounds like it is grounding out and blowing the fuse.

    i have a 1996 suburban that has lost sound to all speakers one at a time now only the passenger side has very low tinny sound and static if i power off the radio and power it back on i get better volume for about ten seconds and then it fades back down. this car had the cdm under the dash which i swapped out yesterday with a unit i grabbed at the junkyard and there was no change in sound. I’m thinking its the head unit that is giving me the trouble . any thoughts also if i leave the power on and turn the car off wait a few minutes and turn the ignition back on all speakers will come on loud then just fade away in ten to twenty seconds with only the passenger front speaker giving some very low sound

    I have a 2002 impala ls. I attempted to put an aftermarket radio in but it wasn’t working right. Finally I got it working then it randomly started losing power and shutting off. Then it would turn back on by itself. I thought maybe the radio was bad so I put factory radio back in. It does the same thing. I can be driving down the road and it just shuts off then turns back on. Sometimes it can be for a second or two and other times it can take almost a minute to turn back on. Also sometimes it’ll stay on for a while then do it again. And other times it will just keep turning on and off on and off repeatedly. The clock resets pretty much every time yet it seems to save my presets. I took it in to a shop and they insisted it was the module I bought with the aftermarket radio. But I disagree because it was doing it for a while before installing that specific module. I originally tried a relocation harness before switching back to stock. Now mind you, all factory plugs are still intact. I never cut them. Anyway, I’m really frustrated with this and would like some assistance if possible. This is the first car I’ve ever had this much trouble with while installing a radio. Thanks in advance.

    Hi I recently bought a double din for a VW Polo 6, after about 6 months my screen becomes white with no sound while playing music and that sometimes happens when I hit a speed hump. I tried to reset it, but nothing happens. I have to wait for a few hours or a day for it to be normal again. Is really stressing.

    i have a 2000 Honda Civic hatchback with cde-w265bt head unit, and a Punch 301m amp powering two 12″ @ 1ohm. before i installed the system the brightness of all lights in the car would fluctuate, the lights still fluctuate but sometimes i need to turn on my blower fan (add more load to the electrical system) or turn off the engine and use only the battery for my subs to work (the light on the amp stays on). I am going to assume there is a problem with my alternator but i would like a more detailed reason as to why this happens as in is my alternator out putting too much power so my amp is shutting off. thanx info is greatly appreciated

    I’m trying to mount a single din deck with a 7″ flip up screen in the dash of my motor home. Everything went fine except for mounting it inside the dash. The factory mount is actually a 5mm flat piece of plastic with a wood grain pattern overlay. There is nothing on the sides or behind to help stabilize the deck. The factory deck was a generic cassette player that hardly weighed anything. I know about the various mounting kits available but have yet to find anything that will help me. Does anybody have any ideas on what I should do? I’d appreciate it. Thanks

    I recently installed a Pioneer AVH-4800BS and it worked great on the first week but now for about 5 minutes after I start my car, it keeps uncontrollably changing the input. When I change it back to what I want it just keeps changing. After about 4-5 minutes on the road it quits and works normally. Tried to see if the remote was a problem so we took out the remote battery but it still happens. Had a friend install it for me but if anyone has suggestions on how to fix it would be much appreciated!

    Two days ago I put in a single din stereo in my van and it worked great. The next day it had no power, someone told me to pull out the bcm fuse and put it back in and that fixed it. This is not a very expensive or powerful system. So last night it did it again, so for the time being it is working. I pulled it out and went threw the wires and interior fuse connected to the unit and it is fine. I don’t want this tearing up my van and I can’t have it just going out all of the time. Is it just a bad unit or am I missing something?

    I have a 99 Chevy Blazer that had the factory am-fm cassette player. I recently purchased the OEM am-fm stereo with CD player and had it installed. The stereo plays beautifully and the clock works but when I put a CD in, the ERR comes on and rejects the CD. I checked the original car manual; it said that it could be the CD was dirty or scratched or it was too hot but I live in Arizona. Does that mean I can’t use my CD 6 months out of the year because of the heat?

    I have an 89 f150 and the original stereo system produced a very low volume which I could not control. So i got new speakers and the same situation occurred.So I hooked up an alpine 7949 and everything worked on it except it had no sound. The speakers are getting power because i can hear them when the unit turns on and off, but no sound.

        No. I ran direct wires from the speakers to my home audio receiver and the speaker worked fine, so I’m guessing the problem was in the stock wiring. I’m waiting for a media player I ordered to come and am going to connect the new speaker wires directly to the players harness. Hopefully that works.

          One set of wires are white and the other ones are a off white grey color one will have a black stripe down it make sure that your colors are all going to the right wires. I had a hard time distinguishing between the white and grey wires they both go to the speakers and if you accidentally cross one wire it could cause the system to not have sound

    2. (Trustno1) says : Reply

      Well I’ll tell you what? There’s a couple of reasons why your not getting any sound from your head unit? One is the deck may have burned outputs on it. Caused by hooking up the remote wire to the wrong wire and burned the outputs of the stereo. Second could be that your vehicle has a stock amplifier that came with the vehicle and you have to bypass that to get sound to your speakers. The best way to fix that is to run your own speaker wire to your speakers. If your not getting sound after you installed it and it powers up, try to hook up a speaker directly to the wires behind the stereo. It should play music? If not then your outputs are burned in your stereo.

      If ur HU has a fuse check it first then check the rest of your fuses in the panel. And for any future work always make sure ur power is disconnected when doing any work on any car audio equipment, meaning if u don’t know the exact fuse, disconnect the battery.

    After installing new speakers in my FJ Cruiser the radio would suddenly turn off once in a while, usually after hitting a bump in the road.
    My radio is a Kenwood KDC-X72. I’ve checked the wires with a volt meter and I shook the wires to see if the power would go off, but it read 12+ volts continuously. I had the test lead connected to the wiring harness plug, so I think the problem must be with wiring harness plug on the radio.
    Could it be that harness plug isn’t making a good connection with pins on the radio? Has anyone ever had to replace a wiring harness plug because the pins in the plug no longer makes a perfect connection?

    i have an aftermarket deck in my 2010 honda civic. after an oil change i was told i needed some type of switch for the oil life indicator to reset. never got the switch instead waited until my next oil change in which i took it to honda dealership and was told my aftermarket install is the reason the indicator will not reset. is there possibly a wire that wasnt properly connected? what can i do to reset this?

      Hi, I have a 2012 Civic, in the owners manual it explains how to turn out that light.
      If you do not have the owners manual then just google it.
      I put an aftermarket in my car, hope my turns off with the manual procedure.

    omg so i have a 1997 saturn SL2. i got an after market stereo from walmart and the wire harnes package. so the problem is the ignitino orange wire off the car has no wire on the new stereo to connect to! like there is 12 wires on the car and 11 off the new stereo. i have no idea what to do when i touched it to the power wire it makes a weird current noise. other than that the new stereo will not turn on at all. please send me any ideas or any web sites to look at. thanks andyichawks@hotmail.com

    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.

    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.

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.

    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.

    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

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?

    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)???

    “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 ?

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.

    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

        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 recently got my car fixed because I had a short that was causing my turn signals, windshield wipers, (and so we thought) my radio to stop working. My radio would turn on but nothing would come out, and now that my car is fixed I do not even have power to my radio or my cigarette lighter. What could be the problem?

      Some head units don’t come standard with a dimmer/dimming feature. Check the manual to see if dimming is a feature your unit comes with

    Is the vehicle’s antennae wire required for the head unit to turn on? For some reason my mount broke loose and my head unit came flying out of my dash and the end of the antenna wire broke off. It still plugs in and you can hear the disc tray start up and the red light under the face plate still blinks but the screen doesn’t turn on. I tried a second head unit I have that I know for a fact works and it did the same thing. Just wondering if my antenna wire is the problem

    I brought my 2010 Dodge Charger to Chrysler Dealership for problem with car radio. My radio works fine for 5minutes sometimes a half hour then the audio just shuts off, no sound and adjusting volume, nothing. But when I stop and turn off ignition for a minute or two. I all returns to normal unit it happens again. The Dealership wants me to replace radio at the sum of almost $800.00. This ridiculous!!!

      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.

    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.

    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!

    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?

    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 🙂

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 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 with solid white line
    Orange (1)
    Orange (2)
    Brown with solid white line
    Lt Gray
    Lt Green
    Dark Green
    Lt 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..

      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.

    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

      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’ve been trying to install a new XD1228 Dual aftermarket radio. I bought a wire harness, and I have more than triple-checked the wiring between the harness and radio wires, they are all correct. The ground wire is connected and screwed down to metal inside my dash. The radio receives no power. Many people say check the fuses, those are all perfect. I proceed to plus in my old stock radio, it receives power and everything is perfect. Then I’ll plug in my new one, I get the fastest flicker of life, then it has no power. I’ve tried with the car on ACC and when turned on. Everything is correct 😐 Any help?

    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?

    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 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?

      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

      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.

      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.

      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.

    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!

      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.

      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.

      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?

      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

    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

      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.

    1. CarAudioNow says : Reply

      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. http://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.

    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!

    1. CarAudioNow says : Reply

      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.

    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?

    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 : Reply

      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.

    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 : Reply

      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 http://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

Iv never had a problam with this equipment . it worked great. thankyou

    1. CarAudioNow says : Reply

      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

    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 : Reply

      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.

      You will need to double check the wires and their corresponding functions. Here’s our page of aftermarket wiring colors and functions:
      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.

      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.

    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 : Reply

      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!

    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

      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.

      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.

      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)

      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.

          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?
