10 Best 6×8 Speakers In 2020

If you want to kit out your car or upgrade the old to the new, then you will be inspired by today's post, as we review the 10 best 6x8 speakers in 2020.

For oval openings, 6 by 8 is a standard car speaker scale. Without any adjustments, most vehicles will house this size, and as long as you know what you're doing, you can fit them in a DIY way.

We picked a handful of best-sellers for you to browse through. Each offers a major upgrade to your regular fitted speakers in the factory.

The positioning of car audio speakers may be restrictive. There's a lot to consider design-wise, as they convert your doors or dashboards into speaker cabinets effectively. Some firms are better at designing their electronics than others which means they can deal with the challenges that can occur.

View The Best 6x8 Speakers Below

1. Rockford R168X2 Prime 6 x 8 Inches Full Range Coaxial Speaker

With this realistically priced 2-way class, a package of two coaxial speakers from Rockford Fosgate, we are getting the ball rolling. They are a typical 6 by 8 well-manufactured oval style. They are currently classified as suitable for use installed on board water faring vessels as a marine speaker.

This is because the circuitry and electronics are secured to protect them and all the materials used in the construction are specially engineered to withstand a wide range of conditions, so that inside the confines of your car they can have great durability.

The cones are made of polypropylene that is vacuum-formed and sit inside a rubber surround to help dampen them. The drivers are powerful and provide stereo audio with a full range.

They have a flush-mounted dedicated silk dome tweeter and an integrated high-pass crossover. With a generous length of speaker cable, they come. For a simple installation, they have spade terminals and the grilles are included.

They have a 55 watt RMS power level and make for a perfect selection of replacement speakers for the factory.


  • + Elements of consistency.
  • + immune to weather.
  • + Cost-effective.
  • + Surrounded by rubber.

Why We Liked It :They are very well-made, offer excellent performance and are suitable for marine installation.

2. Kenwood KFC-C6895PS 6x8" Oval Custom Fit

This moderately priced package from Kenwood is next in our sights, which also makes for an excellent upgrade to the stock speakers in your car. Importantly, for stock replacement, they would need an adaptor that is a fairly easy cut and wire work.

They are a group of 2 coaxial, oval (6x8) speakers that use an automatic crossover to produce wide-range 3-way class sound. They are extremely well produced and the array better identifies the workload for better performance by dividing it between the 3 portions of the spectrum.

They are made from high-quality components and are powered by rare earth magnets and feature rigid paper cones.

They run at a nominal power consumption of 360 watts and at an impedance of 4 ohms they have an RMS of 85 watts.

The audio is very simple, there is good clarity in the mid-range and the woofers are very capable of providing excellent bass presence before the breakup with good headroom.


  • + Quality craftwork.
  • + 3-way option in class.
  • + RMS 85 Watts.
  • + Audio impeccably clear

Why We Liked It :They are another great example of engineering and manufacturing in Kenwood, they do the company a favour that they are exceptionally engineered, well produced and offer mud-free mids of dynamic audio. In a 2.1 or higher system, they are an impressive improvement and sound ace.

3. Kicker 43DSC6804 D-Series 6x8-Inch 200W Speakers Pair

Now they are a perfect alternative substitute for your worn-out speakers in your car for some cool competition from the Kickers fab D-series. They are a 2-way class of low profile, full-range coaxial package measuring 6x8 to accommodate for oval speaker mounts.

The bass/mid driver is made of polypropylene and has a ribbed polyester foam surround that provides the idyllic absorbent surface for unnecessary reverb deadening. They have a dynamic, powerful tone.

They have a large response, and the zero-protrusion tweeter deals with the highs. The tweeter is a high-capacity PEI domed driver which measures half an inch and works very effectively.

They provide great clarity and decent volumes, with an impedance of 4 ohms, they manage up to 50 watts RMS (200 watts peak power) and the grids are not included.


  • + Low profile, zero protrusion flush-mount.
  • + Quality components.
  • + Dynamically balanced sound.
  • + Low consumption.

Why We Liked It :They are another set that performs at the top of their 2-way class, are well put together and have a great dynamic balance of audio.

4. JBL GX862 6" x 8" 2-Way GX Series Coaxial Car Loudspeakers

In our other car speaker posts, we have nosed at the GX series, and we were really impressed, so we literally had to include an entry in the top ten today that is ideal for an oval reception in your car.

They are a coaxial design wonderfully developed that has been well-engineered for optimum efficiency.

The array features a set-up 2-way class that offers fab crossover balance and produces audio with high fidelity. The woofer cones benefit from proprietary PlusOne technology that takes advantage of every bit of space available to provide a much greater cone surface area with matching dimensions than most speakers.

The additional space to vibrate provides a stronger response and eventually enhances bass efficiency. The woofer is combined with a soft dome tweeter that is edge-driven.

They make for a successful upgrade and have a peak power of 360 watts over a low impedance (120 RMS per pair).


  • + Manufactured well.
  • + Tech PlusOne.
  • + Fantastic balance.
  • + Impedance poor.

Why We Liked It:They are a trendy collection that exploits the dimensional confines to maximise the delivered audio.

5. Rockford Fosgate T1682 Power 6"x8" 2-Way Full-Range Speaker

Time for another Rockford entry, a slightly better production package this time around. They are a hot drop-in pair with a shallow depth from the very well received Get Power series.

They are another full-range, 2-way coaxial class package that benefits from Rockfords top line component speaker models' trickle-down tech, such as a proprietary 3Sixty signal processor.

The capable woofer is composed of a rigid yet flexible injection-molded carbon fibre & polypropylene. In a butyl rubber surround, the cones are seated and combined with a small aluminium dome tweeter that has an offset polyurethane cantilever suspension mount. This decreases the cancellation of anomalous reverberation by an anomalous motion.

They use a Vertical Connect Sound Technique (VAST) that, much like the PlusOne tech from the set reviewed above, increases the available surface area of the cones. In fact, it makes them more effective than comparable models by about 25 percent.

They have an integrated concealed crossover (ICC) and they can accommodate 160 watts of 85 RMS with all the mounting hardware and are competitively priced.


  • + Solid structure.
  • + Higher-end technology.
  • + Concept VAST.
  • + ICC's.
  • + Capable woofer and tweeter combo.

Why We Liked It :They are a high-quality, well-built, high-output pair, benefiting from the growth of experts. They have a crossover that is less messy, more robust, and less confusing to match, incorporated but covered.

6. Alpine SPR-68 6x8" Coaxial 2-Way Type-R

Speaker Set

For those with a more capable amplifier, our sixth selection is an oval choice. They are well built and feature components of great quality.

The high-performance woofer features a multi-layer hybrid fibre cone that manages the bass as a standalone option in its stride, while in a 2.1 setup that offers some of the clearest mids we have heard, they are extremely impressive.

The woofer is held in a Santoprene rubber surrounding High Amplitude Multi Roll (HAMR), which allows for sufficient cone motion and eliminates unnecessary reverberation that can make audio musty sound. In their class, the audio is rich and they outperform most.

They are a true power-horse pair of 600 watts per pair / 300 watts each, RMS: 200 watts per pair / 100 watts each with a maximum combined handling. They have a low profile with a depth of 2-9/16 inches at the top.



  • + Well-crafted.
  • + Elements of consistency.
  • + Higher set of outputs.
  • + Audio powerfully complex.
  • + Awesome bass.

Why We Liked It :With much higher-priced coaxial sets, their efficiency is on par. There is a strong description to the audio and the bass is punchy.

7. Pioneer 250 Watts 6 x 8" 4 ohms 2-Way G-Series Coaxial Full Range

For a top notch offering from the people at Pioneer who are constantly producing goods that include their mission of providing affordable quality for all, back to the lower priced regions.

They have a combo configuration with a 2-way woofer/tweeter. The two work well to manage their respective frequency regions with a high degree of precision with a smooth crossover.

The woofer is sculpted from a solid yet lightweight MPP composite by Pioneers. It can accommodate larger inputs and is highly sensitive. It is nestled inside a Conex damper that helps in the rear to overcome wave cancellations.

The 1 3/4 inch balanced dome tweeter is powered by a ferrite magnet and generates bright, crisp elevations very efficiently.

They manage peak power of 250 watts (40 watts RMS), have a shallow mounting depth for easier installation and come with personalised fit baskets and brackets.


  • + Good conception of architecture.
  • + Decent parts for consistency.
  • + Good money value.

Why We Liked It :They are an affordably priced pair that have been well crafted and manufactured, make your car a good upgrade and are easy to mount.

8. Blaupunkt 6 x 8-Inch 300W 4-Way Coaxial Car Audio Speaker

These oval 6 by 8 Blaupunkt coaxial array car speakers are another high-quality alternative marketed as a 4-way class package. They are thoroughly manufactured to a high technical standard and built from engineering experience worth 9 decades.

They feature a polypropylene cone woofer of top quality with a foam-butyl surround and a dome tweeter from Mylar. Ceramic magnets propel them. The aluminium voice coil is resistant to high temperatures, making them much more powerful and providing them with greater longevity for longer use.

Together, they provide a large response and a seamless crossover to provide rich bass tones with balanced dynamic audio.

They are simple to build and have 300 watts of power handling (300 watts peak) and 120 watts of RMS power handling at 4 ohms impedance.


  • + Gorgeously made.
  • + Guided effectively.
  • + Bits of consistency.
  • + Efficient engineering.

Why We Liked It :They use high-quality pieces, keep the ceramic magnets cooler and are very powerful. There are strong dynamics in the audio, but we are not persuaded that they are truly graded as 4-way.

9. Infinity KAPPA-86CFX 6" x 8" Two-way Car Audio

Now for another option with a lot to offer in the 2-way class. This package from the Kappa series from Infinity is a very reliable pair that has undergone rigorous Harman Norm Reliability Testing to prove its value.

They are fitted with proprietary Plus One cone technology that gives their glass fibre woofers a little extra surface space to produce better bass, like the Pioneer pair.

An energetic UniPivot edge-driven Tweeter textile dome supports the woofer. Over-sized voice coils are integrated and can withstand thermal overloads.

They act as a tight unit covering the spectrum, capable of dealing with high input/output and providing smooth balance and crisp information for audio.

They are highly sensitive and have 100 Watts RMS peak power handling, 300 Watts max and a low impedance of 2.5 ohms

They come with all the necessary hardware for installation, including speed clips for easy mounting.


  • + Durably made.
  • + One Cone Tech Plus.
  • + Tweeter for UniPivot.
  • + High handling output.
  • + Excellent recording.

Why We Liked It:They are a high-performance set that is well built for a fair price and offers excellent audio.

6x8 Speakers Buying Guide

While you have probably found that in terms of their design and functionality, many of the arrays available do not vary too much from each other, while some surpass others' capabilities.

We strive to give you a good general overview of what to be aware of before buying in this guide.

In 6x8 speakers, what to look for?

The space available between each item is limited when shopping with a dictated dimension, but there are some manufacturers who implement clever design refinements to ensure that their speakers take advantage of the space more efficiently, work more efficiently, respond more accurately, and are better balanced in the crossover.

In some of those we discussed in today's reviews, this can be seen in the PlusOne cone technology model and the Vertical Connect Sound Technique used.

Bass Response

Just how you like your bass is one thing to remember, as it can be the hardest thing in a smaller space to do justice. It is probably better to go for a 2.1 setup in your car with a speaker dedicated to handling the low-end frequencies and freeing up your left and right to deal with the mids and highs if you listen to bass heavy genres.

In an arranged set-up, speakers typically perform much better. You may also want to take this one step further and invest in the subwoofer if you listen to especially low-frequency genres or if you want to experience the air movement and are not averse to growling distortion.

Amplification Requirements

Your set-up, of course, is primarily determined by your ability to amplify the speaker. First of all, you need to understand how many channels you have and at what power and impedance each is capable of functioning. Some amplifiers have flexible channels that provide a little more wiggle space for the user to play with.

If you don't understand the requirements of your amplifiers, it may be better to look for a specialist to repair or replace your speakers. We suggest replacing each speaker with a model that fits the specs of the one removed if you want to go ahead on your own.


It's not too hard to replace a speaker and if you're willing to do a bit of searching, you can usually find an instructional video or two with specifics online, you can even find a video unique to the model you want to mount on your car itself. Even if you have a little know-how, it is not a big job, it is important to note that letting a professional do the job is recommended.

If you don't have too much experience, since they are already paired to manage the highs and lows together in tandem, you are probably best off going for a coaxial type car speaker, but some cars need component speakers, it really depends on your original set-up.

Component speakers provide more control over the location of the treble frequency, often opting for separate tweeters (high-frequency response speakers) closer to the driver on the dashboard itself. These days, the majority of tweeters will pivot, making the sound more specifically directional and allowing you to monitor where the generated audio is directed. For inspiration and details in its comprehensive buyer's guide, you may want to head on over to our 10 Best Part Speakers post.

The high frequencies normally hold the audio data, then the audio loses a lot of clarity and definition if they are not catered to properly, and it becomes difficult or muffled to hear. This is particularly true for spoken words, so it is important to have a strong mid-range and high answer to get the necessary meaning and avoid misunderstanding if you listen to radio programming or use Bluetooth for hands-free calls in your vehicle.

You need at least a 2-way classified package for full-range sound to better cover the highs and lows, this will usually be a woofer-tweeter pairing with the woofer preferably taking the mid-range in a 2.1 setup, but the audiophiles out there will probably be better off searching for a 3-way classified set to better suit their tastes. A 3-way class package, supported by a dedicated sub-cover, offers a much wider range and richer spatial audio.

As well as the materials used inside the parts, the standard of design and engineering is most important. Both speaker cones need to be rigid enough to withstand the motion, but flexible enough to sensitively pick up and respond to the processed signals. Usually they are of a stiffened paper or pulp composition, occasionally, for instance, this is more synthetic using polypropylene as you would have seen in some of our top ten picks.

The magnets must be of a good quality, and inside the magnetic fields, oversized voice coils respond better. The tweeters should be dome style and they will direct the sound better if there is a pivot installed, providing better definition.


Generally speaking, most dedicated car speakers on the market usually have a bit more to sell than your stock speakers and we see some surprisingly good items that cost very little to buy with a competitive market full of vendors seeking to undercut the next one.

Even the models sitting in the lower priced regions act as a great improvement, there has never been a better replacement for your car speakers than in the current economic environment.

We have outlined a fair few choices that each makes for good candidates and hopefully our buyer's guide will have helped to point you in a little further before you connect with your new speakers.
