ok guys, i got my caddy a few days ago...got in the car today noticed speakers were kinda staticky in the rear, the ones that look like honeycombs, get out of work get in car..very low sounding radio , no base, no nothing, turn car off after driving a bit and boom it works fine but with the static still...what could this be..bringing it in tomorrow am....for a fix!

You mean 5.1 correct? Have you tried playing a DVD 5.1 audio disc yet? Try it and see if it still sounds that way.
