Either the amp has fried from extreme clipping which you should also check the sub.

Or test with a new power wire to see if power is dropping or wire is bad.

There are some people real knowledgable about the inner machinations of amps here. Unfortunately I'm not one them.

Check that the voltage is correct with a DMM on the power wire and the remote wire. Also check that all of the wiring from the amp to the sub is in good shape and not shorted out. I've read some amp won't turn on if there's an output short.
