Great quality amp.

I have this amp on my car and the settings and quality of this amp are top of the line. It makes it super easy to have just 1 amp instead of 2 separate amps. Lots of power, great sound quality and good built quality.

This Amp is a Champ!

Fully tune-able true 5 channel amp. Top of the line quality all around.
so far I can't find one issue with this amp

Sonic Electronix even has the best price but.........

1 HUGE PROBLEM....
Under the description it says it requires 1/0 Gauge power and ground wire.
This is absolutely incorrect. It can only fit a maximum of 4 gauge power and ground wire. So when I ordered this amp I purchased a 0 gauge install kit to go along with it. Thanks to Sonic Electronix's advice I wasted $100 and set my build back by two weeks. Hopefully they will change this information immediately so no one else makes the same mistake.

Can't complain

This amp is perfect. A little big but i got the room so that doesn't bother me. Its the length of my sub box that has 2 12's and it actually makes them hit really hard, don't let the low watts fool you. draws a lot of power a cap is a must. i have a 3 farad cap and my lights still black out at night if up loud. You can't go wrong with this amp though it does it all great. Everyone who hears my system just sits with a smile on their face because they can't believe how good it sounds.

Will always prefer this to anyone who wants highs lows and the mids

awesome 5 channel amp!

I was a little skeptical about ordering this amp at first because I had never heard of Polk audio in car audio. The amp is pretty typical as far as settings go, but I didn't find it to be lacking anything at all. The INCLUDED bass remote is just icing on the cake. The sound quality is great, no audible distortion on the amp end. I'm currently running Hertz HSk 6" components 125w in the front. I was planing to cross over the rear channels to the front for more power but I didn't need to. The sub is a 12" Infinity Kappa 350watts at 2 Ohms the amp powers it just fine. The amp looks great, perhaps the only down side to the amp is its size. All the same its smaller than doing the same job with 2 amps! And the price is spot on.
