Sounds like a lose wire in the harness either yellow, red or black. Pull radio and shake the wires around untill you find it or the face plate is lose.

Problems with amp or stereo

check out
this site has your stereo's wire diagram.

The amp wires only go to the rear output (rca jacks on back of cd player)

I love loud music

i have alpine stereo's in all my vehicles and i have had this problem. if you run a 10-14 gauge constant wire from the stereo directly to the battery the stereo will not shut down in protection mode. it is not the cd it is the stereo going into protection mode because of lack of current not voltage. i hope this helps after i did this i could play the stereo as loud as it can go until my battery died

Do you have to run in AUX to get XM Radio? Your receiver and unit sound like its ok. This could be a problem with your provider. Contact your provider and their tech dept can help you organise a solution. Is your radio, XM ready?

Radio sound but NO cd or ipod sound

Radio is screwed.

But try these these steps:

Clean the eye of the head for reading CD. Must open up the radio.

Sound Issues

The player has a built in safety device which only allows it to turn up so high. It help to avoid burning out your equip ment. Best way is to put sound on one device 3/4 ways up and then use the other device for adjusting the volume from there.

For sound in one channel; either there is a wire unplugged or not getting a good contact, or the player is set for mono instead of stereo
