Compact, powerful, works great.
This amp is compact but has great output. The built-in crossovers and controls work really well. I'd buy it again. I just wish I could have found a matching subwoofer amp that had really good output.

Good for the money
In a jeep wrangler I used this as a 4 channel to power front and rear MB quart formula 6.5 inch 2 ways and MB quart 1" tweetes in the tombstones. Crisp clean sound as loud as you can stand it. the built in high pass filter isn't bad but could be better. The signal on feature works as it should but requires a moderate volume to activate and it will shut down if there is any silence or quiet parts of the song. So it will not work for phone calls with this feature on whatsoever. Bottom line is you get a pretty good bang for your buck if you know how to install car audio and adjust amps properly I'm sure this one will last a good long time.

Perfect for a mild upgraded over stock
Well it wasn't long after I installed this that I blew all my factory speakers but I knew that this amp was way to powerful for them and had already ordered upgraded speakers (MB Quart) also. Amp does get a little warm but I am not gonna baby my stereo. Sound quality is great looks are great too with the exception of the emblem on the front just fell off like it wasn't secured well. It uses little Allen head screws to secure all the wires which is good but either the Allen head on the tool or the screw itself strips easily. But I do have a heavy hand so it could be me, but I like to make sure everything is gud'n'tite. Would I buy this amp again YES. Would I recommend it YES. Good price on a Good amplifier!
