The woofer design benefits from JL Audio's vast woofer design experience and advanced modeling systems. The 6.5-inch (165 mm) format is a direct fit in many vehicles. Multiple mounting patterns are provided on the woofer frame for easy installation into most vehicles that accept a 6.5-inch (165 mm) speaker.

Frequently Asked Questions (FAQ)


This is likely a polarity issue. If the positive and negative wires are swapped on one speaker, they cancel each other's bass. Ensure the wider terminal is connected to the positive wire on both the left and right speakers.
No. The C2-650x features a low-profile tweeter design. Unlike cheaper speakers with bulging tweeters, these are designed to fit behind most factory grilles without needing modifications to your interior door panels.
Yes, but they may sound quieter because they draw less power from the factory amp. To restore the full volume and "punch" JL is known for, adding a small 4-channel amplifier (45–60W RMS) is highly recommended.
No. To keep your install clean, use a vehicle-specific speaker harness (e.g., Metra 72-series). It plugs into your car's factory connector and slides onto the JL terminals, making the install "plug-and-play" and reversible.
These move significantly more air than stock speakers. Use the included foam gasket between the speaker and the door. For the best result, apply a small piece of sound-deadening material to the metal around the speaker.
Yes. The C2-650x uses a polypropylene cone and a rubber surround. These materials are UV-resistant and designed to withstand the high heat of a rear dashboard without cracking or warping over time.
Factory holes are often too large for standard screws. Use the Speed Clips (U-nuts) by sliding the clip over the mounting hole in the metal door frame; this gives the screw a threaded surface to bite into.
Usually, this is amplifier clipping from a factory radio. The C2-650x is rated for 600W RMS. If you push your radio to 100% volume, the signal "squares off." Keep your max volume at around 85% to maintain clarity.

Great sound

Great sound, deep bass. Good upgrade to factory speakers. Quality you won't regret.

Nice sounding value speaker

I'm powering these speakers off a Pioneer P4000DVD and they sound very good for under $100. I had to set the high pass filter at 80hz but that is pretty typical for running off a deck.

If you want bass, I would avoid these. You should have a sub or at least 6x9s in the back to complement these speakers.

Excellent Choice

I installed four of these in my wife's Toyota 4-Runner to replace the OEM speakers. The sound quality is impressive to say the least. The only equipment powering them is a JVC KW-XG700 with no external amp. As already stated here, the quality of these speakers is excellent, complete with rubber cover magnets that are huge. After installation was complete I performed the "how much can they take test" and was impressed at how loud I was able to crank it before the sound quality degraded. Bass is outstanding for speakers this size and the highs are nice also. These are a great choice if you're looking for a nice improvement over your factory units.

decent speakers for the price

replaced rear factory toyota speakers with these. huge difference in sound quality and distortion/volume. used with scosche brackets for 6.5s and metra wire adapters. install wasnt too crazy. pleased with the purchase; it was either these or Alpine Type Rs. powering them with an Alpine ktp445u and they complement my dual 8 inch JL W3 ported enclosure very well. if your looking for good speakers and working within a budget, go for these. if you can spend a little more, id go for C3's or C5's (if you can amp them).

Great speakers!

These are some of the best speakers I've heard--ever! They match up all the frequencies very accurately. They're rated at 100 watts max. only but if you have a head unit that pumps 50 watts X 4 (@ 20 watts RMS, give or take), these'll be perfect for you. They're rated at 60 watts RMS, so pretty much any HU that you match them up with will do the job nicely. However, if you're planning on hooking up an amp you're probably better off getting something else (i.e., Infinity Kappa), since these babies pump up 91 dB with the head unit alone! I actually replaced a pair of Kenwoods for these ones because of their better quality of sound--and I was not disappointed. The manufacturing quality is also remarkable! I've never seen speaker magnets all covered with rubber. They're still 6" even but JL Audio makes a 6.5" also of the same specifications, which might fit some cars better.
