To achieve a wide frequency response, 6x9s are the best choice in speaker size. When compared to 6.5″ components or 6.5″ coaxial speakers, they are the superior choice for boosting bass. Adding a high-quality pair of these speakers is a fantastic way to give your stereo system some mid-bass oomph while keeping the mids and highs clear and efficient.
Here are the top-selling 6×9″ car speakers of this year in Sonic Electronix based on customer feedback!
NVX NSP69

Durability: 4.7 | Value: 5 | Features: 4.7 | Design: 4.9 | Usability: 4.9
Next in line in the N-Series are the NVX NSP69 6×9″ speakers. They don’t break the bank and are surprisingly long-lasting and high-quality in sound. The durable yet lightweight polypropylene cone material faithfully reproduces the mid and low frequencies.
The Nitrile Butadiene Rubber Enclosure’s linear bearings make it possible to achieve extreme precision. While the speaker’s Stamped Steel Basket guarantees it won’t wobble for years to come. Finally, the High-Temperature KSV Voice Coil provides superior current distribution and heat dissipation. These parts can create high-quality speakers with a wide frequency range when put together.
The NSP69’s silk dome tweeters, measuring 20 millimeters, do an excellent job reproducing the NSP65’s extraordinarily smooth and silky highs. These features are often only found in expensive component systems, but NVX has implemented them in their low-priced speakers.

“Awesome Value!” – ★★★★★
I was looking for a replacement set of speakers for my car. Let me just say I am indecisive when it comes to things. I have done months of research before actually hearing about this brand. I was referred to it by a friend of mine. Needless to say, I am thankful I took his advice!
For the installation, I elected not to get the wiring adapters because I plan on running my own wire for when I add an amp to my setup later on down the road. These were a direct drop-in replacement to my current speakers in my 2013 Dodge Dart.
Now for the sound, AMAZING! My stock speakers were terrible. Everything sounded like there was static in them. With these everything is crisp and clear! At first, the bass was alright, after using them for a bit (“burn-in time”) the bass is A LOT better. Nice and punchy. Keep in mind I still have the stock head unit and no amp.
I am extremely happy with these and will recommend them to anyone who needs a budget-friendly replacement. If you are having a hard time deciding get these. You will not be disappointed!

Durability: 4.9 | Value: 4.9 | Features: 4.8 | Design: 4.9 | Usability: 5
The DS Series 6×9 3-ways lets you have it all in one speaker. Either with stand-out looks or sleepers in your factory grilles, the DSC69304s make the most of the DS series’ technology and your tunes. A pair of zero-protrusion PEI tweeters give your highs the crispness your factory speakers couldn’t muster, and the woofer takes care of the rest.
Since your job’s already likely to be more accessible, add in some NVX Sound Dampening to keep out the road noise and accentuate the power of these speakers. This 6x9s shine in an amplified system, built to handle up to 90 watts RMS. Put more effort in and add a Kicker DX amp to push these further. Stamped steel framework, polypropylene cones with Extended Voice Coil technology, and more deliver high-quality sonic satisfaction. The DS series employs high-sensitivity motors to bump your volume up. Balanced dome tweeters with neodymium magnets, UV-treated polyester foam surrounds, and other durability factors ensure long-lived sound.
Kicker’s DS Series speakers improve your sound while making the job a breeze. These coaxial drivers are built to fit most vehicles without the need for modification of your door panel.

“Nice & Loud” – ★★★★★
Bought these to replace the stock speakers in my 2015 Ram 1500. The magnet is very large and does not fit in the doors so you need to also buy or make some spacers for the speakers.
These sound amazing! Very loud and have great mid bass. Highly recommend it for the price.

I wanted some Focal speakers but they were super expensive. I found these nvx carbon fiber ones and decided to give them a go. I was impressed by the packaging but more impressed by the sound. I will for sure be trying out some other nvx stuff in the future

Sonic Electronix CustomerInfinity Kappa 93ix

Durability: 5 | Value: 5 | Features: 5 | Design: 5 | Usability: 4.7
The Kappa speakers by Infinity represent an innovative step forward for car stereos. This speaker has Infinity’s patent-pending Plus OneTM woofers, which produce powerful, detailed, and musically engaging bass and highs. Higher-volume listeners will appreciate the silky highs and increased thermal power handling of the edge-driven textile dome tweeters’ larger voice coils.
In cases when a three-way system is requested or can be accommodated in the factory, a midrange speaker with a bandpass crossover can be added to a two-way component system to turn it into a three-way system.
Kappa’s 2-ohm design draws every watt of power from the amplifier or head unit for remarkable performance, and each model’s voice is tuned using audiophile-grade inductors and capacitors, resulting in detail and precision unsurpassed by other manufacturers in their class.
Item highlights
• 330 watts Peak Each, 110 watts RMS Each
• Textile Edge-driven Dome Tweeters
• Glass Fiber cone material
• Impedance: 2.5
• Sensitivity: 96 dB
“Excellent sound quality” – ★★★★★
I installed the speaker’s in a 2008 Toyota Tundra extended cab with a JBL sound system. I installed them in the front doors they were a little deep for the doors but I was able to cut the webbing out of the inside of the door panel and they just do fit with spacers. They sound amazing. I am glad that I put six by nines back in the door even with the extra trouble

Sonic Electronix CustomerJL Audio C2-690tx

Durability: 4.1 | Value: 4.2 | Features: 4.4 | Design: 4.7 | Usability: 4.7
JL Audio Evolution C2 speaker systems deliver an impressive audio performance solution and value. The technology of the Evolution C2 Series has been drawn from JL Audio’s experience in woofer and tweeter design. They have been engineered to deliver adequate efficiency while retaining a smooth mid-range response with low-frequency extension. The smoothness of response and the freedom from distortion make the C2 Series speakers truly one-of-a-kind and enjoyable for everyone. The resulting product delivers performance for any car audio enthusiast at a price that won’t break the bank!
JL Audio C2 tweeters incorporate silk dome diaphragms to deliver smooth high-frequency transitions, on and off-axis. Silk is a natural material with inherently good characteristics as a tweeter diaphragm. In addition to being very light in weight, silk exhibits excellent damping properties, which reduces ringing and resonances in the tweeter’s passband, leading to a smooth, pleasing high-frequency character free from unnatural sibilance or exaggerated brightness. This is why many audiophiles prefer a Silk Dome Tweeter for its balance.
JL Audio Evolution C2 coaxial speaker systems feature mineral-filled polypropylene cones, extended excursion capabilities, and stamped steel frames. In addition, the woofer design benefits from JL Audio’s vast design experience and advanced modeling systems. This use of proper high-quality components and advances allows the speaker to perform better than any other speaker in its price range. The C2-690tx, specifically, has a good frequency response of 53 Hz – 22,000 Hz, continuous-power handling of 70 watts, and a solid efficiency of 93.0 dB, giving it the ability to produce smooth mid-range and highs.
Item highlights
• 225 watts Peak Each, 70 watts RMS Each
• 3/4″ Silk Dome Tweeters
• Mica Injected Polypropylene – MIPP cone material
• Impedance: 4 ohms
• Sensitivity: 93 dB
“Simply Awesome” – ★★★★★
I was skeptical at first because of the high price point compared to competitors but I read up on this product online and it got great reviews. I decided to try it for myself and I have not been disappointed. The low notes are defined and the high notes are pitch-perfect. I love these speakers and you should try them for yourself.
