i have a pretty old soundstream 2 channel amp that i bridged to power my sub. it stopped working, so i tried hooking it up to the left output and the right output, neither worked. i checked the fuses and of course they were blown, so im like.. nice, thats the problem. i change the fuses, still nothing.

any ideas? any thing else i can do to test it, or is it time for a new amp?
