Table of Contents

I’d hazard to say that car speakers are the factor you should look at most in your quest to build the best sound system for your vehicle. There are basically various car speakers sizes – 6X96X86.55×7, 5.25. These are the most common speaker sizes, and the difference between them is pretty self-explanatory, but I’ll go ahead and give it to you since I like making things clear, and I’ve got the time.

Basically, a car speaker size is measured depending on the size of its woofer. And the bigger, the better. And Because large speakers have bigger woofers, they tend to perform very well in low frequencies reproduction, which results in better sound quality.

Don’t get me wrong here; we’ve come across several smaller speakers that do very well in sound quality and performance. So, we’ve decided to dig deeper, look beneath the surface and review some of the best 5.25 speakers on the market. Of course, we won’t simply pinpoint those speakers without actually telling you why they’re worth the money; keep reading, and we’ll tell you.

Any of the following speakers would be great buys. Much of it comes down to personal taste, specific interests, and budget. Like with any product, you can get a solid set of speakers if you’re willing to shell out a bit more, but there really are great products in every price range.

1. Polk Audio DB521 5.25-Inch Coaxial Speakers

Polk Audio DB521 5.25

We have reviewed many Polk Audio speakers on this site before, and the story hasn’t changed. Polk Audio produces a quality product at a fair price. In addition, almost all their speakers are marine certified, which means they can withstand harsh environments.

You can mount them in your car, in your boat, as well as in an offroad vehicle. They also pass the industry’s toughest standards and ultimate stress tests, including drop testing, sun and salt exposure, as well as shock and vibration tests to simulate the most demanding road conditions.

If you’re looking for a small set of speakers and want to keep the costs to a minimum while getting the best value for your buck, we can’t think of a better option for a set of speakers than DB521.

As for the downsides, it’s challenging to think of any. If anything, I’d say the narrow frequency range doesn’t reach as low as some 5.25 we’ve reviewed.

2. Rockford Fosgate R1525X2 Prime 5.25-Inch Full Range Coaxial Speaker – Set of 2

Rockford Fosgate R1525X2

You and I both agree that factory-installed speakers are nothing close to perfect. In most cases, their sound quality is nothing to brag about. If you are looking to upgrade the sound quality of your stereo, consider getting new speakers.

You can begin with installing topnotch 5.25-inch speakers like the Rockford Fosgate R1525X2. They will not disappoint. The Rockford Fosgate R1525X2 is a 2-way 5.25-inch speaker with a power rating of 40 watts RMS, which is not bad for a 5.25-inch speaker. In addition, their sensitivity rating is 88dB. On top of that, they have integrated high-pass tweeter crossovers for a well-balanced sound.

The frequency range of these speakers is 62 to 20,000Hz. This means that mids and highs are pretty good. The speaker comes with Vacuum Propylene cones with a rubber surround to give you a decent bass. As a result, you’ll get a crisp and clean sound regardless of the frequency.

But, as expected with all other small speakers, the bass is not loud enough to shake your car seats.

As a result, you’ll get clean and crisp music all day long. With a frequency range of 100Hz to 18,000Hz, the mids and highs are excellent. But as expected, the lows are not as great.

Not to say they are bad, the sound is better than that of most factory speakers. However, if you need to add an extra punch to your music, consider adding a sub.
