Crossfire 600.4

This is amp really kicks ass in every way. I have the gains down with about 2.5 volts going to it from my pioneer head unit and it's more than enough power for my door and dash speakers. the amp is very dynamic and musical. A great amp to run to front speakers and a pair of subs too! Crossfire is really a quality product and I've been in car audio since the days when phoenix gold m series and soudstream amps ruled the world!!
