One kicking amp!

Paired with component Momo's in the front and Mobile Monitors in the rear, this amp blasts the speakers without an OUNCE of distortion. Crisp, clear and LOUD. Reproduces signals with great accuracy! A must have!

Outstanding

This amp replaced two 2 channel MTX amps and i'm glad i did it.
The signal to noise is amazing regardless of gain adjustments, no more hiss. The power is pure, clean, and the quality rates with the best. A Pioneer DEH-4900IB and EQ746 feed the PA500-4, and it feeds 3 pairs of Polk coaxials along with Kicker and Streetwires cables. This amp will eliminate any worries of noise or sound qualities after your install vs. other amps that I've wasted time and money on.
I highly recommend the PA500-4.

Awesome amp

I think Polk makes great products anyway, and this amp is no exception. I have used it in several configurations (i.e. powering 2 front speakers, 2 front speakers and a sub, and soon will be hooking it up to my front/rear speakers and have a dedicated mono for my sub). In all modes, this thing cranks! You son't be disappointed with this one, plus it looks col in the trunk!

Amazing amp...

I've had this amp for about two weeks now and it is very amazing. It's pushing a pair of db6501 and db691. Very nice, cool, quiet and clean. This gives all of the speakers all the power. This amp is B.I.G.!! (which is good because it distributes the heat well). It makes my honda accord sound superbad!

Great Amp!

The amp has plenty of power. The amp is pushing a Bostin Acoustic 10 inch in the trunk of my 2001 Mustang GT and it sounds great. I have the amp turned down because of the amount of power it pushes, so I am sure it will push a much bigger sub-woofer. The only thing I can say about it that isn't super positive is that the amp is a little long, so make sure you look at the specs. It would not fit under my seat.
