1. Polk Audio DB522 DB+ Series 5.25" Coaxial Speakers

Our rating: 9 / 10

Check Price on Amazon

Pros:

  • Design matches car dashboards perfectly
  • Great sound for the price
  • Marine-certified
  • Polk Audio customer service

Cons:

  • Heavy for its size.

The Polk Audio DB522 DB+ series speaker line-up offers you six different options of car speakers (5.25″) carefully designed to complement your car’s interior. Each option comes with a foam gasket to make them waterproof and marine-certified.

The speakers come in pairs, making the lineup more affordable. Not to mention, Polk Audio offers these speakers with a 2-year warranty that’s backed by their customer service.

It’s important to note that the DB+522s are not magnetically shielded. This means that they won’t work with any listening devices that make use of a magnetic technology such as a built-in compass. However, magnetically-shielded speakers are a bit more expensive and probably overkill for your car.

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

Our rating: 9 / 10

Pros:

  • Power handling- 250 Watts
  • Sound quality
  • Clear highs
  • Smooth, super-clear midrange

Cons:

  • * Overall can be a little bright

The second on our list is the Rockford Fosgate R1525X2 Prime 5.25 Full Range Coaxial Speaker. This speaker features a split construction with a 0.74-inch soft dome tweeter paired with a multi-layered, mica polypropylene cone woofer. The material gives the speaker its ample volume, producing a massive sound without being overpowering.

Since Rockford Fosgate prides themselves on making great subwoofers, they knew they had to also focus on the tweeter. This developed a tweeter that is much more efficient, ensuring high-quality sound without sacrificing the power handling.

The company has done extensive number crunching to make sure that you are getting the most sound quality for your money. Their unique and proprietary cross-venting design on the back of the driver gives the speaker some extra bass output, allowing for every speaker to sound great, even if you’re not using a subwoofer.

The TS-A1370F has been specifically designed to send out the best possible sound from the stock amp in the head unit, which is what you end up hearing from your existing speakers.

The woofer benefits from a high-tech cooling system while the magnet is Fluid-Cooled. The voice coil also benefits from a Heat-Sink system and the speaker cone is treated with a UV Reactive finish. The speaker diaphragm is also treated with a Diamond-Cut finish and the tweeters are Dynamic balance, with polyester material.

What is the best wattage for car speakers?

Your most important consideration when selecting a speaker is power handling, but you also need to look at the speakers frequency range and impedance as well. The best speakers are generally 10-60 watts.

Generally the higher the wattage, the louder the speaker will be, which is why you may opt for higher wattage speakers even though having a lower wattage rating may be more power efficient.

If you typically listen to podcasts, then a low wattage speaker will likely suffice. On the other hand, if you tailgate often and have particularly loud friends, then higher wattage speakers might be the best option for you.

The best 6.5″ car speakers for sound quality are Bose, Rockford, Polk Audio, and Alpine. These will deliver crystal clear highs and booming lows.

Rockford Fosgate, Infinity, and Peavey are best for bass.
