Best amp in the world. Honestly, its built like a tank, looks very professional and hides all the wires with the shrouds on. The internal capacitance is insanely high, there are three rows of 10 high value capacitors buffering the regulated power supply inside this baby. The lowpass crossover is 18db/octave the 15hz subsonic filter is 24db/octave.
it has a 1/2" thick aluminum heatsink which covers three sides of the amp and has never gotten too hot to touch even after several hours of play during roadtrips. This only drawback is that it uses a/b circutry and for that reason I would get the polk 500.1 that uses class D for subs.
Probably one of the reasons why in the future I'm getting all Polk-only car audio gear, i've had very good times with them and most of the stuff i've heard from them sound fantastic, this just reinforces my beliefs; i just am weary of them mostly because of the price of some of their things. Hopefully in the future it won't be an issue.
