Im running my entire system off of this amp and it's never given me problems, it doesn't even heat up!! My system - HU Pioneer DEH-P7200HD - Front and Rear Speakers are PowerBass L-6502X and one sub a Kicker comp10" in a ported box.

This is a pretty good amp so far using it for mids and highs.

It has a small foot-print so it can be installed under a seat and still leave room for cooling.

Biggest con is it uses Phillip head screws for the terminals which can strip easily.

The reason the manu. locates the power and RCA's on opposite sides is for a particular reason. The reason being that the power wire 12V DC is a square wave and the wave or alternation between cycles changes from an upper voltage ( being RMS or Vp-p ) to an level voltage ( being 0V reference regardless ) so the RCA's can pick up what we like to call an loop interruption ( Ground Loop Noise ) what happens is that you will be able to hear a high freq. ( high Pitch ) Noise through the speakers caused by either the amp or miss-routing of cables. having the RCA's routed on the same side of the vehicle as the power cables ( Remote/ on-off, or/both supply 12V ). the best advice to give is always route the RCA's on the opposite side of the vehicle in reference to the power and/or the remote wires. This method will not allow ( depending upon grnd. reference) a noise to build and be heard through the speakers. always remember as a mind reference tool power on one and sound on the other.

I bought this amp for a buddy that wanted to upgrade his stock speakers. I have it run to pioneers 5x8s up front and pioneer 6x9s in the rear, and wow this little amp does a perfect job. Nice and clear with no distortion. puts out plenty of power with plenty to spare. I highly recomend this amp. The only thing that i dont like about the amp is; the amp preouts are on the opposite side from the power ground. it makes it a little akward tho tuck the wires away. But what do you do. Its a great amp and well worth the money.
