Why did my amp stop working?

If the ground connection is poor or isn't connected at all, the amp might fail to turn on or not work very well. If the amp has good power and ground, the remote wire has voltage when the head unit is turned on, and no fuses are blown, then you're probably dealing with a busted amplifier.

What can damage an amplifier?
