I just installed another headunit and it is not playing cds. I am most positive everything is wired correctly, but I could have missed something. My radio works just fine. I did notice i blew a fuse inder the hood could i have blown one else ware? When I try playing a cd the head unit says its playing it but no sound any suggestions?

hmm

Go back over ur speaker wiring. make sure you don't have positive & negative mixed up. According to your decription the new headunit IS reading the cd's.

Is the cd playing but making no sound? if so....

You probably used the Blue to power up the factory amp. Connected to a white wire in the car. This is the power antenna wire, thus the radio works, but not the cd player.

Use the Blue/white wire instead.

Ive noticed over the years that some stereo companys have power turn-on wires in EITHER blue or blue/white......bastards. It threw me for a loop last time I did an install for somone...I was lookin at the amp dumbfounded.....turn on lead was blue/white, but no amp power....traced grounds....power.....fuses.....everything checked out ok.......WTF!?!?!?!?......out of curiosity I jumped the power to the power turn-on on the amp.....fired right up......the lead was unbroken all the way back up to the head unit.....so I switched the turn on wire to the blue wire on the HU wire harness....Bingo!!!!

But in most cases, HU harness power turn on is Blue/white stripe. just thought id share my horror story
