I've had this amp for around a month. First I had it hooked up to a 15" Rockford Fosgate T1. It sounded amazing until I got crazy with the bass knob. I now have it hooked up to a spare p2 I had and it still sounds good, just waiting for the p2 to blow though. It stays pretty cool under pressure, but the amount of power its pushing out does cause an insane voltage drop in my electrical system. Buying this amp I would also look into upgrading the big 3, running at least 4ga power wire, and then maybe another battery. Overall I got what I expected with this amp. Pure Rockford Fosgate quality. Nothing less.
