Might want to get a new wiring harness, I had some problems with the one that came with mine. You sure you hooked everthing up right? I mean it's getting power just sounds like your speaker wires might be loose on the plug of the harness.
i'm surprised you got power, gm cars like the sunfire ::i installed a pioneer on:: same year and all. they require a external power feed if u use a metra kit you have to wire your own other then that not much else you could have wrong.
i have the power wire run to the fuse box,so the power isnt a problem.I was told i may be missing a wire,or may have to run one myself...any idea which one that would cause this problem? 2 days now tryin to figure this out with no luck
