VERY GOOD AMP!!!
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. I love the sound, very natural and rich sounding not harsh at all and very loud when you need it to be..Im very impressed by Powerbass for there ability to bring a good product at an affordable price.....HIGHLY RECOMMEND...

Just for your Info.
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.

great amp
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.

PowerBass ASA 400.4x
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.
