I have had this amp for quite a while; it is a very efficient amp, it hits pretty hard, and music is clear. It has a built in fan which is a plus. It can push a good amount of power as well, I would recommend this amp.

I recently had this amp installed to a pair of 6 1/2 kenwoods in the front and a pair of 6x9s in the rear and they sound awesome! This amp adds much needed clarity and presence not offered by self powered cd players. For the money this amp is definitely worth it. The excelon brand is amazing.
