i got a new alpine deck yesterday.

my fronts work fine, but when i fade it to the rear, everything gets real staticky

the shop couldnt tune it or anything...i didnt have any speakers in at the time, my rear right 6x9 doesnt work.

is the deck the problem?? bad install job?

 

what kind of speaker are they? They could just be on their way out.

 

they have been fixed. i brang it back to the shop and there was a bent pin in the wiring harness
