I was given a kenwood amplifier. The only problem w/ it...is it sometimes shuts off due to vibration. IF i tap the amp pretty hard ..it will work..but then shut off a few moments later due to the subwoofers vibration..ive taken the amp apart and cannot find anything loose...but maybe thats because i dont know what im looking for...any ideas??

ALSO i have a kicker zr240..one of the channels doesnt work..my friend killed it on me when he had it bridged mono at some very unstable ohm load..so only one channel works now..andyone know what kinda chip/fuse id need to get to fix it? thanks

 

on the kicker amp you've blown the left or right channel, its not exactly a fuse that needs to be replaced...but more work to be done on it.

On the kenwood, check the internal amp grounds as it sounds like the problem.
