Get a DMM (digital multimeter) and check the resistance on the voice coil(s).

If they are considerably off of the nominal resistance they are supposed to present then it's likely your subs are toast //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Remove the sub from the box and make sure all speaker wires are secure. Also, double check all of the connections to the amp.

If that doesn't work... Hopefully it's not the sub at all, and your ground wire is loose, and is turing the amp on and off...

See if the ground wire is loose.
