I had the red version of this hooked up to 2 PA Mofo 12s in a labyrinth ported box kinetic battery and all zero guage wiring. There's literally only one thing I dont like about this amp, no cooling. But, It slammed soooo hard, you couldn't drink anything in my car. It broke my review mirror and it fell off. Deactivated the cruise control when driving, couldn't light a lighter, vibrated my gutters from a block away. Alot more to list but, all this was done with all settings on zero. Gain, bass level, bass boost, loud. I could say so much more good stuff about this amp, dont doubt it. It is well worth the money. Everyone knocks PA. Ive changed so many people's opinions. Get it. And give it some juice, you will sh** your pants the power this can put out. It may not put out the full 3500rms, but it is tough. I had a 160 amp alternator, had a few friends in the car and got ballsy, turned everything up, fried the 250 amp fuse, starter, alternator.
