Audio Systems: No Sound when CD plays, antenna wire, power antenna

Question
just installed new deck in my dodge ram 01 and no sound plays when you try and play a CD. the radio works and can hear sound but when i change the source on the deck to CD there is no sound and you can see the cd playing...it will seek tracks and everything just no sound...its like the deck works except for the CD sound...i double checked the wiring and it must be right cuz speakers work with radio. ive tried serveral differant CDs and no sound. never seen radio sound work but no CD.

Answer
Does there happen to be a power antenna wire, as well as a amp turn on wire coming out of the deck you installed? Common on Sony products, shuts off antenna wire when on CD. That in turn shuts off the infinity Dodge amp. Just one possibility. Get back to me.
