forgetable

i bought this amp about a month ago and had it hooked up to a kicker comp (12") heated up and maxed out in about 2 minutes of medium playing then it would over heat and the protect light would come on

Decent, when not put to the max

I have owned this amp for over 2 years and it has performed beautifully in 2 different cars now. The power level is all a normal person needs powering a single-sub with un-powered mains. Very satisfying mid-bass amplification for dub-step.

I had an issue when I first bought it where the protection would come on when listening to heavy bass, but I found fine-tuning the levels both improved sound quality (it removed distortion I didn't even notice) and totally eliminated the problem. The installers I used were hacks and tried to milk all they could out of it to make me think I bought something better than I did (don't try to max this thing out... it's touchy).

Eventually I will upgrade, but I'll probably just get one more of these guys and use it for my mains. Great product.
