ground wire on my amp slipped out this am..... i went to slip it back into slot and tighten it and it popped out and sparked on metal part of amp. I've got infinity midrange up front with a kenwood amp pushing 8s. Now the front speakers and amp will not work. backs play fine. fuse in amp is ok. any suggestions??? thanks.

 

Sounds like you sent a surge through the amp and blew the outputs for the front.

 

is the kenwood amp just pushing the front or is it pushing the rear and front?

 

or you could have sent the amp into a sort of protection mode. i've seen this a million times especially on kenwood amps.
