This amp kicks ass, it's advertised as 150 watts per channel but the rating tag that came with the unit from factory testing had it at 168 per. I am powering 4 Hertz HSK 163 component speakers that are 150rms and 300peak, I have the gain on the amp up about a 3rd of the way and my system is loud as hell with awesome clarity. I originally installed an Alpine mrp-f550 that was 90rms and 180peak, it was not enough for my speakers after 2 weeks I bought the amp (pdx-4.150) I should have bought in the first place, I was trying to save a couple bucks, Instead I spent more time(installing the pdx) and money than I should have. This amp is worth every penny especially at the price Sonic electronics is selling it for.

I can't recommend this amp too highly! It puts out well above its rated RMS. Usually in the 175watts per channel region. I have mine powering my fronts and bridged to my sub and it sounds amazing.
SUPER convenient if you are limited for space or If like me you have it mounted in a stealth location such as under a seat. Sound quality is top notch also.

i have this amp in my 2007 gmc i have it pushing a pair of Diamond Audio S600A and it sounds amazing, also the small size of the amp is VERY convenient to mount where ever you need it.
