Best 6.75 Car Speakers

Many cars come with factory systems and stock speakers that are very bad at delivering the audio experience that makes the ride so much more enjoyable.

Since we consider ourselves to be dedicated audiophiles, we’re fully aware of the struggles that car owners experience while trying to make their very first steps toward making audio upgrades.

If you’re one of the audiophiles we’re talking about, the chances are that you may have already experienced the issues we’re talking about.

Best 6 3/4 Full-Range Speakers

Rockford Fosgate P1675

Rockford Fosgate is probably a dream of every audiophile out there. We know we love this speaker more than life, it’s simply that good. RF speakers are instantly recognizable, mostly thanks to their simplistic yet extremely effective approach to aesthetics.

The circular frameworks have become the brand’s stamp and the industry standard, but we simply love how they make up for what they lack in looks – with top quality. Now, we can’t emphasize enough how important this is.

There are so many fancy-looking speakers on the market at the moment, some of them costing quite a lot. The problem with all these speakers is always the same – poor sound quality.

However, the moment you mention a brand like Rockford Fosgate, you’ll have the ears of everyone present.

The first thing we love about the P1675 speakers is their ability to produce clear, natural, and detailed sound output, regardless of the volume.

If you love blasting the life out of your car system, these speakers will be your allies in fulfilling your infernal audio fantasies.

The design is so clever that it helps you fit these speakers in most cars and vehicle compartments.

Regular car subs feature screw holes, but RF went one step further and replaced the annoying screws with slots that are perfect for adjusting the speakers during installation. You may fit them however you want.

The speaker also comes armed with PEI dome tweeters, capable of delivering clear and sharp sound even at high volumes.

Pair those with butyl rubber surrounds and mineral-filled, injection-molded polypropylene cones, and you have yourself exceptionally balanced and defined bass, as well as accurate frequency reproduction.

Trust us when we say that these speakers may help you achieve the sound you’re looking for. To sweeten the deal, the speakers come with the Integrated Concealed Crossovers, which allow you to mount your speakers on black boxes for additional support.

Pros:

  • Easy to use and install
  • Exceptional audio performance with no distortion
  • Grill covers included

Cons:

  • Poor bass response
  • Don’t work well with all car amplifiers (some car amplifiers can alter sound quality)

JL Audio C3-650: Check Price On Amazon

Jl Audio C3 650

When it comes to the best car speakers out there, we can’t but mention the real giant among the brands – JL Audio.

Their C3 speaker systems are on another level. Why? Simply because they come so packed with awesome features that allow you to choose the top-class sound configuration that matches your sound needs in your car.

This level of convenience and comfort is rarely seen on the market today. You can also choose to mount your tweeters and woofers together or separately, which increases the level of convenience even more.

The main purpose of a C3 component car system is to provide you with an exceptional listening experience by producing an incredibly rich, detailed, and crystal-clear sound.

Since the entire speaker system is adjustable, you can position your C3 speakers to get a perfect audio experience with each use. C3 speakers are an excellent solution for vehicles with very little or limited space.

Now, what we really like about this JL Audio speaker is the ability to mount the tweeter inside the woofer.

This feature alone is worthy of your full attention as it helps you get a coaxial speaker with a full-range dynamic sound that will completely change your audio experience for the better.

The C3-650 speaker system comes with 6-½” woofer filled with mica polypropylene that accurately and strongly supports both low and midrange frequencies.

The speakers have a specially-designed frame capable of resisting any unwanted resonances to ensure you have a perfect audio experience without any interference.

With 75W RMS and 90dB sensitivity, the C3 650 speakers can deliver an amazing frequency response, ranging from 48Hz to 25Khz.

More importantly, you may use these speakers to handle extreme levels of high frequencies without any risk of overheating. The 1” silk dome tweeters will provide you with the musical quality you deserve.

Pros:

  • 4 levels of tweeter presence and 3 midrange settings
  • Separate premium components for easy personalization
  • Easy installation and protection from overheating
  • Low-powered and high-powered speaker compatibility

Cons:

  • Sound distortion on higher frequencies
  • Not fitting in some vehicle compartments

Rockford Fosgate P1675-S: Check Price On Amazon

Best 6 3/4 Component Speakers

Rockford Fosgate P1675 S

The first thing we’ve noticed about P1675-S is the powerful bass.

The speaker packs a punch with an excellent low-end that is simply perfect for music genres that require top-quality bass. The bass thump delivery is unprecedented with quite an impact.

That’s mostly thanks to KICKER’s amazing Vertical Attach Surround Technology that helps mount the rubber surround on the polypropylene cone of the woofer.

Thanks to this technology, the P1675-S has an extended surface area of the cone by almost 25%. The result – powerful sound and bass that you can feel in your diaphragm.

The P1675-S may have the same polypropylene cone in the woofer, but this cone isn’t your average car speaker cone. It’s much stiffer and more resilient. In fact, we were surprised by how durable and stiff it was when we first tested the speaker.

This stiffness results from the special addition of minerals, which allow for much better dampening.

It allowed us to push the speaker to its very limits without ever experiencing sound distortion or losing any of the precious sound details.

From an audiophile’s point of view, this is what a speaker should be.

While all these features sound more than amazing, it was the polyetherimide tweeters that really did it for us.

PEI tweeters are the industry standard today, and they handle high frequencies extraordinarily well without becoming distorted.

Aside from that, we have all the goodies here, such as 92dB sensitivity, 75W RMS, and a wired remote. What more can you ask from a simple car speaker?

Of course, not everything is perfect with this speaker, and it has its downsides, which are minimal, to be honest.

One of the downsides is the sound tends to break up a bit when you turn the volume to the maximum. While this isn’t anything major and speakers with silk tweeters tend to perform much worse, we want to make sure you have all the information you need to make an informed decision before you make your purchase.

Pros:

  • Powerful bass that performs well high volumes
  • Crystal-clear highs
  • High compatibility with both high-powered and low-powered car systems

Cons:

  • There is some sound distortion on highs when you hit the max volume
  • The speaker terminals could be better

Component vs. Coaxial Speakers

Component speakers are usually the number one choice of most audiophiles. The reason behind this choice is quite simple – component speakers are an excellent solution for enhancing a particular sound.

You can tell component speakers by their very distinguishable and noticeable features, such as two external crossovers, two woofers, and two tweeters.

When you put all these components together, you get a harmony of sound as they all work together to produce extra quality sound.

Component speakers also provide the user with an additional benefit of achieving optimal imaging by installing the tweeters separately.

Component speakers can deliver clear mids, lows, and highs and come with woofers with a frequency range of 20 to 200Hz.

Coaxial speakers are full-range speakers that come with various features and sound components. Their frequency ranges start from 20Hz and go up to 20 Khz.

Since there are so many coaxial speakers out there, you should go for those that can produce good treble, mids, and bass.

Coaxial speakers can go as high as 90+ dB sensitivity and have the main purpose of converting power into decibels. Pair them with a good amplifier and achieve maximum sound and impressive performance.
