6.75 Car Speakers Reviews

1. JL Audio C3-650 6-3/4"

It just doesn’t get much better than JL Audio speakers. They sound great, they look great, and they throw some serious sound. Take a look at these 6 ¾” from their Evolution C3 series

Specifications:

  • Sensitivity: 93 dB
  • RMS: 75 watts
  • Peak Power: 150 watts
  • Frequency Response: 48Hz-25kHz
  • 2way/3way/4way: 2-Way Component

The Good:

At 75 watts RMS, these speakers are quite loud, but they don’t sacrifice any clarity or punch that often gets lost in sheet volume performance.

EDITOR'S RATING:

They also have an exceptional frequency response, so your music will sound crisp whether it is in the higher or lower frequency ranges.

The Not-So-Good:

This is a component speaker set, which means that crossovers and speakers all have to be installed individually.

Woofers typically get installed in the door enclosures, and then the tweeters and crossover networks have to be wired and installed separately.

This can make things a little tricky, especially if your vehicle does not have pre-cut spaces for tweeters in the interior panels.

You may also want to consider upgrading your stereo or using an amplifier given the power draw of 75 watts per channel, since not too many car stereos actually push that much power to their original speakers.

Besides that, I'd recommend these JL as the best 6.75 car speakers overall.

Pros

Cons

2. Infinity Kappa 60.11CS

Infinity Kappa manufacturers some of the best sounding speakers money can buy, and the specs on these speakers alone are clear evidence of that.

They build them to be powerful, but more importantly they build them to last.

Take a look at what makes these speakers a superior upgrade choice.

Specifications:

  • Sensitivity: 93 dB
  • RMS:  90 watts
  • Peak Power: 180 watts
  • Frequency Response: 45Hz-35kHz
  • 2way/3way/4way: 2-way Component

The Good:

First of all, the frequency range on these speakers is ridiculous.

They can throw lows that sound like a contained earthquake, and yet neither he mid range nor the treble gets lost in the boom of the woofers.

EDITOR'S RATING:

All that power and clarity draws 90 watts RMS, and they peak at 180 watts, so these speakers are ideal for integrating with a powerful aftermarket amplifier.

Honestly, these speakers would make good door speaker replacements or a fine addition to any trunk mounted speaker enclosure.

The Not-So-Good:

It’s a component speaker set. That means additional work mounting and wiring the tweeters and crossovers.

If you are up for it though, these speakers are probably the best option for giving your car stereo a significant upgrade.

Speaking of upgrading though, you are going to want to upgrade your factory car stereo if you opt for this speaker set.

At 90-watts RMS, they are going to draw more than most factory car stereos can handle.

Pros

Cons

3. Kicker 40CSS674

Whew! Hang on tight, because these Kicker component speakers are pushing big sound without a big price tag.

Built of high end construction materials and packing some serious power, these Kicker 6 ¾” speakers are ready to bring the ruckus. Check ‘em out:

Specifications:

  • Sensitivity: 90 dB
  • RMS: 100 watts
  • Peak Power: 300 watts
  • Frequency Response: 35Hz-21kHz
  • 2way/3way/4way: 2-Way Component

The Good:

These are among the most powerful replacement speakers you can buy, and their bass performance is legendary.

Users who want to add some thicker bottom to their car stereo need look no further.

EDITOR'S RATING:

Short of adding a powered subwoofer, these are about as earth shaking as they get.

However, thanks to the tweeters and crossover network, the bass never drowns out the rest of the music.

The Not-So-Good:

At 100 watts RMS and 300 watts peak, theses speakers need some powerful amplification to drive them, so an aftermarket car stereo is going to be a must-have for your upgrade.

Installing component speaker sets is also a lot more difficult than coaxial speakers, so be prepared for some tapping and drilling to get everything setup correctly.

Pros

Cons

4. Rockford fosgate Punch P1675

Rockford Fosgate’s Punch series provides probably the most balanced audio clarity out of most speakers in their class, and the 6 ¾” P1675 lives up to its name.

Here’s what makes these speakers great:

Specifications:

  • Sensitivity: 89 dB
  • RMS: 60 watts
  • Peak Power: 120 watts
  • Frequency Response: 60Hz-24kHz
  • 2way/3way/4way: 3-way Full Range

The Good:

Lower power draw at 60 watts RMS means that these speakers are going to work well with your existing factory car stereo.

That does not mean, however, that they sound anywhere near wimpy.

EDITOR'S RATING:

These speakers can deliver some heavy lows, rich mid range sound, and crystal clear highs effortlessly.

They are tough to beat in terms of overall sound quality.

The Not-So-Good:

Brackets require modification to mount these speakers correctly, which may intimidate some DIY installers.

Honestly though, most of the time “modification” means that you are punching out come tabbed holes or components that were designed to easily modify.

There is also the minor issue that these speakers have a higher low-end range than other speakers in their class, which might be noticeable to some listeners, but others might not actually be able to distinguish the difference.

Other than these two minor concerns, these are great speakers.

Pros

Cons

5. Rockford Fosgate R1675

Another offering from Rockford Fosgate for the more budget or power consumption conscious, the Prime series delivers radically improved sound without overloading your stereo or your budget.

Specifications:

  • Sensitivity: 91 dB
  • RMS: 45 Watts
  • Peak Power: 90 watts
  • Frequency Response: 52Hz-20kHz
  • 2way/3way/4way: 2-way Coaxial

EDITOR'S RATING:

The Good:

These speakers sound amazing for their size and power draw.

They also have excellent midrange performance despite their lack of a third speaker component.

They are also extremely easy to install thanks to the included speed clips and wiring.

They may not be ground shakers at 45 watts, but less likely to be too much for your factory stereo to handle.

The Not-So-Good:

I wouldn’t recommend these speakers if you intend to upgrade your factory car stereo later on, as they peak at 90 watts and wouldn’t be ideally suited for aftermarket amplifiers.

Pros

Cons

Final Verdict

​While it may seem like there is a lot to consider when selecting your new car speakers to upgrade your car audio experience, it’s really quite simple.

Do they fit? Can my stereo power them? Am I going to be able to install them easily? Aside from these considerations, your only concerns are going to be budget and specs.

My personal recommendation is for the Infinity Kappa 60.11CS 6-3/4" component speaker system.

Their performance overall is tough to beat, and the sound quality is really out of this world. Sure, you may have to spend a little more time and TLC on the installation process, but the performance in audio quality and power is well worth the effort.

If you are looking to upgrade your speakers and your car’s stereo, definitely consider buying Infinity Kappa 60.11CS speakers, and turn every car ride into a musical extravaganza.

They are definitely my recommendation for the best 6.75 car speakers for the money.

  1. See if you can help me I got two pairs of Rockford fosgate 6.75 3-way I am looking to set them up if an amp would you go with the Rockford fosgate 4×400 or the 4×600 amp

    • Hi Jack. I’d need to know either the exact model (ideally) or the power of those speakers. The P series (nº4 of this list) can handle up to 120W peak, so I’d say you’re more than sufficiently served with a 4×400 amp if those are the ones you’re using.

  2. Thank you for your help Alex they are rate at 120 watts max now I got that taken care of what do you think about the Rockford fosgate subs personally I always had kickers which they were the 15 L7 now I am in the market for 12s and I can’t go with the 12 L7
