I have a 93 dodge intrepid. I installed my old cd player in this car that previously worked. It would play the radio with sound but when I put in a cd it shows the track playing but there is no sound I tried all types of cds. I then bought my friends cd player wich is like a 300 dollar mp3 player cd all that good stuff and hooked that up I have the same problem plays the cd just no sound comes out for it I have all the wires hooked up correctly on the wiring harness I believe I have installed like 5 cd players before this is the first time I have had this problem any ideas?
