Is my amp blown?

[DjDan101 10+ year member]

I have a 325.1 Rockford Fosgate amp and I was hooking in a new sub and all the sudden my subs went crazy for a half second and now they aren't hitting. I know they aren't blown because I got them to hit off a different one but now they won't when hooked into mine. The power light for my amp is still on, is it blown? I know it's a stupid and basic question but I've never blown one and I didn't know if that would cause the power light to go off as well.

did the sub push in and out really fast? if so u might have a shorted channel.

Yes and it made a weirrrrrrrrrrrrd sound. It went in and out then died. It has two + and - slots, but it's a single channel. How do I fix that??

if your good with a soldering iron give a try. if not get it repaired it should be that much. but your channel has shorted in it. u gota remove the output transistors drive transistors and some smd resistors....its work lol.

I opened it hoping it would all be right there, but I'm not near good enough to do that lol. I have a guy that wants to trade me for a sub I'm not using for a new amp but I'd like to have some stuff to experiment with so I think I'll take it in and hope it's cheap lol.. thanks!
