Kicker Amp
I had this amp hooked up to one of my solo-barics. It was in my friends Super Bass box. With this amp and that sub i pulled 141 decibels. Thats a lot of power from such a small amp.

Good Stuff
I had this amp hooked up to two 10" CompVRs and the whole thing went prefect together. I also tested it on my friend's 12" Audiobahn and that sounded great as well. It's a good amp for smaller systems. It's a little pricey if you ask me, but it does get the job done.

Great amp!
I had this amp hooked up to 2 Diamond Audio M3 12s and wow did it hit hard. I couldn't believe what 400 watts of power could do. The system was already in the car when i got it from my cousin so I don't know if the price was good or not, but overall great amp, not much else I can say.
