JL Audio C2-650x

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.

Installed in 2000 Dakota Quad Cab paired with JVC KD-AR8500 and JL VR650CSI in the front. Think it sounds GREAT!! Metalhead!!

I had it for 6 months, it sounds great for the cost.

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.

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.
