Conclusion: Just bought and installed JL speakers on my Hayabusa as a replacement for 4" Infinity reference and they out perform reference speaker by far. Using a 2 channel 300 Watt Rockford Fosgate amp to boost the sound and with a little tweeking of the amp they loud with crisp base. Excellent buy!!
Summary: I am very happy with the speakers. It was worth every penny and the time to put them in. I also put C5-525 speakers in the rear. I can drive in my Lotus-Elise with the sound turned down and hear every nuance of the music.
Summary: For all of the folks who want a clean, rich, full bass tone - these are great! I have 1" tweeters in the doors and 3-way 6x9's in the back dash. After I installed these I get a bass sound that fills the car. It completes the sound.
Pros: Fit perfectly - wired in parallel with door tweeters coming off a four channel amp. This makes wiring and power supply simple and effective.
Cons: I would like to see them handle about 5-10 more watts and come without a tweeter.

Conclusion: After fitting a JL Audio amp & speakers to my Jaguar XKE I added the JL C2 400x to the front console area which is limited in space, the JL's perform beyond their size & price! Sonic Electronix dispatched quickly & efficiently, good service, would definitely use Sonic again
