Why Trust Our Opinion on Car Speakers?
CarAudioNow is an award winning automotive blog, founded and built from the ground up by car enthusiasts over a decade ago. Between our editor, Kameron, and a few selected qualified writers, we’ve installed and tested a wide variety of speakers in cars, boats, golf carts – you name it. We know our speakers, how they should sound and perform and what’s a good value for your dollar. We get our hands on every product that we test in person – many of which are purchased and some provided by a manufacturer. It’s a combination of these tests and extensive research that lead us to our recommendations. And we’re frequently testing new speakers for our lists.
CarAudioNow and its writers don’t use AI to throw regurgitated information about a few car speakers on a list and say they’re “the best” either. We’re focused on providing meaningful lists, with accurate and useful information that will help you make an informed decision on a product. And we do this because we genuinely enjoy or highly regard the stuff we add to our lists. Our readers and our reputation are both more important to us than a quick buck or the top rank on Google – although both of those would be nice! Read more about how we choose our top lists here.

Infinity Reference 5030cx Quick Review
Originally introduced in 2019, the 5030cx is still the reigning top pick on our list. Not only has the Reference 5030cx built a reputation for their ability to handle power with clarity and longevity, they've done so at a very competitive price point. These 5.25” Reference component speakers take advantage of patented Plus One™ technology that allows for more cone area. A larger cone area can impact things like sensitivity and frequency range. A general rule of thumb, the larger the cone area, the better the speaker is at producing lower frequencies (bass). And for the highs, a .75” edge-driven textile tweeters hit the high frequencies with ease, even when pushing the system to its max.
Although these may not be the absolutely best performing speakers on our list, what we think is great about these speakers is how universal they are. With a 65W RMS power handling and 93dB sensitivity rating, they're a great candidate for an external car amplifier, but also a fantastic match for those just looking to use a factory or aftermarket head unit for power. And when you combine their performance specs like these with the fact that they're relatively affordable, they really are a great pick.
Reasons to Buy
- Good choice for factory location replacements
- Durable speaker with a reputation for taking abuse beyond its limits
- Crystal clear mid and high range
Reasons Not to Buy
- Limited Low-Range Frequency limits
- Use of an amplifier is recommended to get the best sound
- They do not come with grills
Best 5 1/4″ Speaker if Money Were No Object
Focal Performance PS 130 FE
Latest Prices
Key Features
- 2-way 5” component system with Inverted Dome Tweeters and crossovers
- Frequency Response: 75-28k Hz
- Power Handling: 60 watts RMS, 120 Peak
- Adjustable Tweeter levels
Focal PS 130 FE Quick Review
If you're less concerned about price and more about competitive-level speaker performance, consider the PS 130 FE. The French engineers at Focal have squeezed all the best parts of their mind-blowing 6.5” speakers into these stunning 5 1/4” components. The innovative flax cones do more than just look good, too. In fact, the design of these flax fibers were engineered to create hollow chambers and an increased surface area for tight, clean and warm sound. They're well-known for delivering smooth, precise sound with incredible mid-range frequencies and some good bass (for a 5 1/4″).
The speakers combine this innovative Flax technology with Focal’s renowned TAM aluminum/Magnesium inverted dome tweeters to produce one of the best sounding and performing 5.25” component speaker systems on the market. The TAM technology is interesting. If you listen to them in comparison to a standard inverted dome tweeter, the key differentiator is their ability to directionally focus sound at a much wider area. Directionality is less important with these which is key for installations that may limit the ability to focus tweeters directly at the area you want them to.
The included crossover is prewired for two-way installation but can be converted to a three-way crossover for adding additional speakers. The tweeters include mounts for surface, angled, and recessed installation. Aluminum baskets and butyl surrounds give these speakers the toughness to handle pro-level power.
Reasons to Buy
- Produces natural, warm and accurate surround
- High sensitivity for excellent response
- Great technology offers enhanced performance
- Well-built for guaranteed durability
- One of the most attractive speakers on the market
- No distortions or unwanted vibrations
Reasons Not to Buy
- Expensive
- So good you might have to upgrade your whole system to keep up with them
Best Factory Upgrade 5 1/4″ Speaker
Hertz CK 130
Latest Prices
Key Features
- 2-way 5.25” component set with 1” tweeters and package-specific crossovers
- Frequency: 65-22.5k Hz
- Power Handling: 70 watts RMS, 210 watts Peak
Hertz CK 130 Quick Review
The latest Cento series of speakers from Hertz continue to expand the company’s reputation for high quality factory upgrade speakers. The latest CK 130 components continue the tradition by offering premium performance and a reasonable price. The CK 130 system includes two woofers, two tweeters, and matching crossovers.
The woofers use a mica powder-injected pressed paper woofer cone that is light and responsive, though not exotic. It performs better than expected because of the extra step Hertz goes to Klippel certify each speaker they produce. Klippel certification uses computer analysis to identify distortion from a speaker when the motor is in motion. Eliminating the distortion produces a speaker that lasts longer and sounds better.
Don’t let the basic materials fool you into thinking this is an overpriced speaker. The quality you get from Hertz is remarkable and you will immediately hear a major difference in your music when you swap out factory speakers for the CK 130 components from Hertz.
Reasons to Buy
- Excellent factory upgrade option for impressive mid-range improvement
- Detailed tweeter is superb and is an instant upgrade over factory designs
Reasons Not to Buy
- Materials are budget but the speaker’s price tag is not
- Not well suited for low-power head units without amplification
Best Convertible 5 1/4″ Speaker
JL Audio C3-525
Latest Prices
Key Features
- 2-way 5.25” components with 1.2” removable or mountable tweeter and two crossovers
- Frequency Range: 48-25k Hz
- Power Handling: 75 Watts RMS/ 225 Watts Peak
JL Audio C3-525 Quick Review
Sometimes, a coaxial setup fits the bill. Other times, a separate tweeter can help round out your sound and add some directionality to your system. But why not have both in one? If you buy the C3-525 5.25” convertible component system, that's what you get. Simply remove the tweeter from the center of the cone and voila, you have a component speaker. Put the tweeter back and you can use it as a coaxial. Beautiful design, and really a testament to JL Audio's R&D team.
JL Audio built these with tough-as-nails mineral-filled polypropylene cones and injection-molded baskets for a rugged package. The oversized 1.2” removable tweeters can be flush or surface-mounted for versatility.
JL engineers packed all that strength in for a reason. These components are rated for up to 75 watts RMS, so show no fear throwing some serious power at them. In fact, JL Audio claims you can put up to a 150 watt per-channel amp on these speakers.
The removable tweeter is obviously the trick feature here, and JL Audio made sure that the little speaker was silk-domed and capable of handling as much juice as possible without making your ears tickle from harsh highs.
Reasons to Buy
- Removable, oversized tweeter
- Broad frequency range
- Durable Speaker
Reasons Not to Buy
- Higher cost than other systems
- Amplifier recommended
- The interface between the removable tweeter and the woofer may become damaged and stop working
Best Budget Pick 5 1/4″ Speaker
Rockford Fosgate R152-S
Latest Prices
Key Features
- 2-way 5.25” component with dual .50” tweeters and inline crossovers
- Frequency: 58-20k Hz
- Power Handling: 40 watts RMS, 80 watts Peak
Rockford Fosgate 152-S Quick Review
You would expect a component set at this price point to sound a lot like something you bought at a swap meet. In a surprise move, the folks at Rockford Fosgate have put together a package of budget-friendly components built around the same technology as the up-market Power Series – for less than half the price.
The Prime Series components use a cost-saving mica-injected polypropylene cone and a foam surround, but these speakers produce a warm, rich, and full sound without reverb. These are among the very best 5 1/4″ component speakers for a direct factory upgrade, alongside the Hertz we recommended earlier on our list. The package is rounded out with a set of ½” mylar-balanced dome tweeters and inline crossovers that are intended to simplify installation.
It is hard to beat the built-in quality of Rockford Fosgate speakers. The Prime series component speakers carry a 1-year factory warranty. These speakers have been a popular upgrade since 2016 and have held a spot on our list for some time. You can't go wrong with this option.
Reasons to Buy
- Low-cost upgrade
- Rockford Fosgate quality
- Excellent sound from factory head units
Reasons Not to Buy
- Foam surrounds are the least durable
- Limited power and frequency range
