Polk, Polk, Polk I can't say enough about this brand!
I have this amp in my car (Chevy Aveo Sedan) powering two Pioneer 6x9 speakers and a Polk SRA-DVC 10" sub.
To start, this amp came on time. Amazon is great when it come to coordinating with outside sellers to accomplish shipping.
This amp, is great. I have had no problems with the power ever dropping, amp overheating, or it not functioning properly. I replaced an old mono JL amp with this beast. There are two channels powering the subwoofer because...well there isn't a real reason, who cares bass is great! The two Pioneer speakers each have their own channel also.
My car is no big SUV so I needed an amp that would not suck my poor battery dry. I have a Duralast Gold and have had no problems since I installed the amp.
The amp does what it is supposed to, it supplies continuous power without over heating and running my car out of battery. The Polk emblem even light up with blue LED lights, pretty nifty!
I highly recommend this product for a car audio installation.
