This amp hasn't heated up like others have stated in reviews, but of course, I am running it at 4 ohms. It adequately pushes two skar audio 8" vd-8 dual 4 subs in my truck with each sub wired at 8 ohm (coils wired series). I also listen to the radio a lot, and this is the first class d that I've owned that DOES NOT hose my FM reception. I think those who have it heat up are running at a low impedance and/or have too small of wiring for the power/ground. The only negative I can think of is that it didn't quite do rated power on the amp dyno.
