JL Audio C2-690tx vs Other C2 Series Speakers (6x9 Upgrade Comparison)
- • Larger 6x9 Cone Advantage: The C2-690tx moves more air than 6.5” and 6x8 C2 models, delivering stronger midbass and deeper low-end response.
- • Higher Output & Efficiency: Designed for louder performance with less distortion, especially at higher volume levels.
- • Best C2 Series Midbass Performance: Provides noticeably more punch and body compared to smaller JL Audio C2 speakers.
- • Factory 6x9 Upgrade Optimization: Ideal direct-fit replacement for OEM 6x9 door and rear deck speaker locations.
- • Full-Range Sound Improvement: Enhanced clarity, vocal separation, and smoother highs without needing a subwoofer.
Frequently Asked Questions (FAQ)
- • Why do my JL Audio C2-690tx speakers sound weak or have no bass?
This usually happens due to incorrect wiring polarity, air leaks in the door, or missing door sealing. Fix it by correcting wiring and properly sealing the speaker.
- • Why do my new JL Audio C2-690tx speakers distort at high volume?
Distortion typically occurs when low frequencies are not filtered. Set a high-pass filter between 70Hz–80Hz and reduce bass boost.
- • Why are my JL Audio C2-690tx speakers not loud enough?
Low volume is usually caused by an underpowered factory head unit. Adding a 50–100W RMS amplifier will significantly improve output and clarity.
- • Why don’t I hear more bass after installing JL Audio C2-690tx speakers?
These are midbass-focused speakers, so performance depends on proper installation and sealing rather than subwoofer-level bass output.
- • Why don’t my JL Audio C2-690tx speakers fit properly in my vehicle?
Fitment issues are usually solved by using spacer rings or adapter brackets to match factory 6x9 mounting depth and alignment.
- • Why does my JL Audio C2-690tx sound harsh or too bright?
Harsh sound is often caused by early break-in or EQ settings. Lower treble and allow a 10–20 hour break-in period.
- • Why does one JL Audio C2-690tx speaker sound different from the other?
This is usually caused by wiring polarity or connection issues. Check wiring and balance head unit settings.
- • How do I get the best performance from JL Audio C2-690tx speakers?
Use a clean 50–100W RMS amplifier, proper door sealing, and set a high-pass filter around 70–80Hz for best results.

I HAVE A 2009 CAMRY AND HAVE THESE BABIES IN THE REAR DECK AND THE DOORS ALPINE PDX600 AMP AND THEY SCREAM. VERY CLEAN SOUND:-)
-
I have 3 of these in my 65 Lincoln they fit perfect in the center of the dash. I had to modify the rear deck to fit them, just trimmed some metal, and they sound really good and clean just off the head unit.
-
Great speakers for the money. I run a 300/2 on them. Handle the power with no issues. Very clear bright but not too bright.
-
I bought the c2 6×9, c2 6x0 and the c2 3x5 from you guys and installed them in my demo car. These speakers are awesome! The clarity is amazing! I have recommended these speakers to every customer thats hears them! Thanks for a deal on such an amazing product!
-
I have been a loyal JL customer for several years now. These C2 6x9's are no different to the high level of quality that I have come to know and love from JL products. Great bass from a 3-way speaker with crystal clear highs and true to sound mids. This speaker really can do it all! I would strongly encourage anyone to pick up a set of them, you will not be disappointed!
-
J L Audio is known for its quality.These speakers did not impress me. The highs could have more clarity, woofer doesn't produce the bass expected. Real let down.
-
Great purchase will buy them again for a new truck
-
These speakers really are awesome, the sound quality are unlike any 6x9's I have ever experienced. worked great amplified, and un-amplified, depending on your head unit's output power. These things beg for power though... Holds great bass, but will also work as great mids (not for highs), should you already have subs in place. Overall, great speakers...

Loved it
-
I have these mounted in the front doors of my '12 Grand Cherokee and love the staging. They have a fair amount of bass and can get pretty bright if need be depending on your set-up. All in all, they are flexible in terms of their frequency response and make designing a stereo system fairly satisfying.
I have the 6.5 version of these in the rear doors and together with the fronts are run off a JL Audio 360/4, it's more than enough and I'm very happy.

A simple word would be “love” such a good looking stereo to start with and then the sound is elite
