Works well and looks awesome.
It does what it's supposed to. It makes my music louder, and so far hasn't blown up yet. I have heard from reviews and other sources that this would overheat easily, but as of yet I don't believe it has.
Far as I know, it's as good an amp as any other, and it's working great for me.

Amazing Amplifier
I am using this amplifier with 2 sets of Rockford Fosgate P1653 3-way coaxial speakers. It CRANKS and is distortion free all the way to where my ears cant take any more! Do not spend 600 dollars on a similar JL Audio Amp. I also have Another Power Acoustik pushing my Infinity Sub and It POUNDS it. I consider myself a very picky audiophile and this amplifier does it all. Very High Signal to noise (no background hiss), Low Distortion and Has Plenty of Power. The Light-Up eyes in the skulls are neat looking too.
