6.75 Car Speakers Reviews

1. Powerbass S-Series

For avid music fans, the Powerbass S-Series Full Range Speaker is a must-have. This coaxial speaker offers fantastic performance and at a great price too.

Specifications:

  • Sensitivity: 88 dB
  • RMS: 50 watts
  • Peak Power: 150 watts
  • Frequency Response: 63Hz-20kHz
  • 2way/3way/4way: 2-Way Component

EDITOR’S RATING:

The Good:

These speakers are easy to install and perform exceptionally well. They have a good range and the design ties it all together to make a complete perfect package.

The tweeters are impressive but you may need to tighten them for better performance. All in all, for its price, the speakers are a good deal.

The-Not-So-Good

To get good bass, you may need to purchase additional speakers. They do not handle all car stereos very well; you might need an amplifier for some types of cars.

Pros

  • They are easy to install
  • Exceptional design
  • Affordable price

Cons

  • The bass end is not very good

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 the mid-range nor the treble gets lost in the boom of the woofers.

EDITOR’S RATING:

All that power and clarity draw 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

  • Supreme audio quality
  • Superior audio firepower
  • Powerful enough to use as door speaker replacements or in amplified trunk enclosures.

Cons

  • Component speaker system installation requires some skill with tools and at running wires out of sight.
  • Power demands for these speakers really require a powerful aftermarket amplifier to reach their full potential.

3. Kicker 43DSC6704 D-Series

These speakers were made and designed for performance; they come with UV-treated form surrounds which get you the realism and power you deserve.

In addition, they come with a highly sensitive DS motor that delivers even at high volumes regardless of whether you use a high-power KICKER DX amplifier or a factory head unit.

Specifications:

  • Sensitivity: 93 dB
  • RMS: 60 watts
  • Peak Power: 240 watts
  • Frequency Response: 40-20,000 Hz
  • 2way/3way/4way: 2-Way

The Good:

These speakers come with clarity and crisp, clear sound like you’ve never heard before. 

EDITOR’S RATING:

They recreate dynamic sounds courtesy of the two-way design. As a result, they are capable of loud volumes even when powered by low-power factory radios. The kickers have zero-protrusion, thus they are able to fit into many vehicles.

The Not-So-Good:

They work well, but unfortunately, the bass is terrible at times; you need to have a stereo to adjust it. Also, when you use the new speakers at total volume, they tend to break, so you have to refrain from total volume for at least a week.

Pros

  • Audio quality and performance are exceptional
  • Bass is thunderous yet remains clear and distinct
  • Power handling is immense, peaking at 300 watts

Cons

  • Power draw is significantly higher than most factory car stereos can provide
  • Component speakers require more skill for installation

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

  • 3-way speakers provide exceptional audio fidelity at any volume
  • Power draw of 60 watts RMS makes these ideal factory replacement speakers for use with factory car stereos.

Cons

  • Installation brackets may need modification in order to fit these speakers into existing enclosures.

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

  • Excellent sound quality
  • Low power draw means wider compatibility with factory car stereos
  • Easy to install

Cons

  • Lower peak power means this pair of speakers is less likely to be a good choice for use with an aftermarket amplifier or head unit.

Buyer’s Guide

Car Speaker for All Types of Vehicles

For those looking for a car speaker suitable for their motorcycle, car, or truck, then the Rockford Fosgate p1675 speaker works well with any vehicle. But, as the company owner used to say, if it has wheels, then we have a car stereo for it.  

In addition, the Rockford Fosgate provides its customers with full-range speakers, which are suitable for people who want to do away with their factory car speakers. What’s more, their butyl rubber surround is great for music lovers.

Budget-Friendly Speakers

For the budget-minded customers who don’t mind having a car speaker with less bass, then the Kicker 40CSS674 will work under your budget. On top of that, you have different options for mounting its tweeter. You can either angle-mount, surface, or flush mount it. 

Speaker Material and Design

As important as high-quality sound is on car speakers, so is the design.

When talking about design and convenience, no other car speaker does it better than the Rockford Fosgate P1675. This is because it is made from a FlexFit basket design which allows for small adjustments to the stereo system, ensuring it fits well.

In addition, this product by Rockford Fosgate has a PEI dome tweeter molded with a polypropylene cone that ensures the frequency reproduction is like no other. 

Frequently Asked Questions

Do 6.5 speakers sound better than 6×9?

We recommend that if you don’t have a subwoofer, then it would be best to put the 6×9 in the rear whereas putting the 6.5 in the front. This is because the 6.5 speakers are supposed to give a dynamic sound, whereas the 6×9 will provide better midbass. Generally speaking, the 6×9 does a better job than the 6.5 speakers.

Are Bigger Car Speakers Better?

It is important to note that larger speakers have fewer strained sounds, whereas the smaller ones create a fuller sound. On top of that, with larger speakers, the sound is more natural and realistic. This implies that larger speakers have a rich sound output than small speakers. 

What Are The Best 6.5 Speakers For Bass?

People who love bass when listening to their favorite music should look for speakers with extra big woofer cones like the Kicker 40CSS674, which provides powerful sound output. 

Do 6.5 Speakers Work in a 6.75 Hole?

If you want to replace the 6.75-inch speakers in your car with 6. inch speakers for vivid sound, the good news is that you won’t need to modify your car for a better audio experience as they will work just fine. 

This is because many speakers nowadays have universal mounting holes compatible with 6.5 and 6.75-inch speakers. However, if you had the old 6.5 audio systems, you would have to buy an adapter plate to fit into the 6.75-inch mounting hole. 

Are Components Speakers Better Coaxial?

Quality-wise, component speakers have a better sound reproduction than full-range speakers. But, on the other hand, if you are working on a tight budget, then the coaxial speakers come at a reasonable price. 

What makes the difference is that component speakers have a single driver with a super-tweeter for accurate frequency reproduction. On the flip side, full-range speakers have the same type of drivers as component speakers, but they are made of low-quality material compared to the ones in component speakers hence the price difference. 

However, if you are looking for speakers that do not require much customization and are a direct fit for the mounting holes, then the full-range coaxial speakers will suit your needs. On the contrary, if you are a lover of customization, component speakers will allow you to be creative. 

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
