Hello - I posted this in the electronics section as well, but I figured someone in this forum may be able to help me. I am having problems installing a CD player in my 97 explorer. It took me awhile to find the correct wiring harness but finally I found it and hooked it all up. The CD player powered up but there was no sound. I brought the CD player into BEst Buy and had them hook it up to verify that my CD player was operating correctly and it worked fine there. I have installed many decks in the past and have never run into this problem. My Explorer has radio controls for the people in the back set. Could that be the problem. any help would be greatly appreicated. Thanks
