[QUOTE="Rawr-DQ, post: 7544975, member: 558585"] unfortunately, after re-installing my car audio I found my sundown amp going into protect.It goes into protect immediately; the power light turns on about 1-2 secs later; 5 seconds later the two relays marked with a purple X close/open(click)...; unhooked from speaker; I found manufacture damages that were covered in glue, marked in black; red. In pink there is some rubbing damage to the winding; no metal caps blown; the plastic ones which the top may have some give; each one can depress at-least a mm or so. That's all I can tell visually. I cannot smell burnt electronics; nor are any burns prevalent on top of the board.I've built small circuits and studied them a lot; and have a megger which probably wont be needed; along with a 400mfd/~2Mohm range; and MV Meter... I also have an oscilloscope. So please help get me to a starting ground on repairing this amp; I have good soldering skills.
