First one I got died after a couple of weeks, but it was just a bad egg. Got a replacement and it hasn't let me down yet! This thing got so much juice to give out, and the little details such as the wiring setup makes this so easy to deal with. From now on, it's Boss half the way and Pioneer the rest.

Hooked up to two Lanzar MAXP154D's running 1000 watts to each @ 4ohms and they POUND! I have all the settings on this amp turned down and they still bang like no tomorrow. This amp is a powerhouse, no complaints!
