MTX makes really good amps at a competitive price, my buddy got a mono amp for the sub and a 2 channel amp for his front infinity's and they are clear at low and high volumes. The amps don't run hot at all, and that was one of the factors we were looking for while shopping for car amps. They seem conservative on the power outputs but they are very good and they look sleek too thumbs up for that.

Another one to look at is the rocksford fosgate's they run a little hot, they're butt ugly, the price is ok but they do the job well IMO.
