i also try to have good sound quality, too

i took the amp apart and it looks like the circuit board from r91p to c91p and then from the c91p to c16p and c31p are fried. there also looks like there was a transistor in between c91p and c16p but it is completely gone. also the cp300 going from the power supply(the big wound up wires) to the negative(big black cylinder) is fried. i have worked on amps before but nothing too complicated(testing wires and bypassing blown channels, my friend and i once found an amp by the river while drinking and got it to work for a short time before it died

) i have read some of the posts hee about building amps and you guys are like way above my level, but i figured that you might know a lamens term way of telling me how to fix it.

Hi Stephan,
Well that sounds like bad news. You must have burned up the power supply when the amp shorted out, maybe burned up plenty other stuffs too. Bummer.

It's not likely to be something you can fix yourself. It might be worth it to take it to a repair shop, be the cost of repair is often more than the cost of replacement. Too bad.

You would probably be better served by purchasing a different brand of class d amp. I have a Directed which is the sister of Orion brand. It has performed flawlessly for 3+ years. Inexpensive refurbs of this and other brands are available at www.Ikesound.com . If you are getting serious about mobile audio you will be getting away from Audiobahn.
