This amp has decent bang for the buck, I'm running two 12's and this amp has decent output but the main reason you buy this amp is for the great price, adequate bump and extreme reliability. This amp has 2 cooling fans, while most amps sold here have none, I've driven from NYC to Florida & back, in the hot summer heat with this amp cranked with no problems since 2005, so 8-9 years for any amp isn't bad at all & buying 2 of them should solve any power issues because with one you're only getting 600-700 watts going to each speaker, with 2 Amps its more like 1200+ watts to each speaker and more power that you can actually feel but for the typical price of just one amp.

This amp is a beast. I have it powering two Lanzar MAXP15D in a ported 3.5cu ft box. It's awesome and I love the remote level control.

This one is in the 99 suburban pushing 2 audiobahn 1400w 12s in a bandpass box.Lots of power but not near the bang for the buck of the Hifonics Brutus
