Xenon 1200.1 repair

[SilverGT]

well I put the amp back together today after taking pix of it. hooked it up to the car with jsut one sub to it. I hooked all up but the remote. then while sitting beside the amp I jumped the remote. fan and led came on then I got sound. no feedback in the speakers eather. Then it shut off and flashed the blue led. second time I hooked up the remote I seen sparks and then nothing. took the amp apart and this is what I see.









I also noticed this. not sure if it should be like that or not.



no the problem I was having this summer was that I was getting a buzz feed back into all speakers and subs with this amp hooked up. soon as I took the rca's off this amp the buzz stopped in all other speakers. would that burnt part be the problem and now finally burnt up? were can I get that part and what is it called or whats the PN?
