I installed this amp, with 2 10" alpines, 2 6x9 alpines, 2 6.5 alpines comp, and 2 4' alpines my god it bonces my mini off the ground. Just make sure to use at least #4 monster cables to power and ground the unit and you will be very happy.

This amp is a great entry level amp or factory upgrade. The sound quality of the amp is really good. The only complaint is if you jam for a long period of time it gets pretty hot.

March 1, 2011 Good enough amp for the $$

Good entry-level 5-channel amp. I have this behind my Pioneer AVIC-D3 head unit, driving Polk Audio DB691 fronts, DB651 rears and a pair of Rockford Fosgate P3SD412 subs. It's a great amp for this at 'normal' volumes, but doesn't have enough power to really drive the bass at really loud volumes. Overall, an excellent product. The only con is the size - it's kind of large.

I am impressed with the sound quality this amp produces when hooked to my Infinity 6.5" rear, 10" sub and 4x6" front speakers. Wow! I am sold on the quality of Infinity.
