i cant figure out how to wire my stereo. i got a harnest for it and connected all the wires together. it was all color coded. and i plugged it in and the power works but not the sound. it plays the CD but no sound was coming out of the speakers. i know it works cuz it was my friends and he wouldnt rip me off.

Mess around with the speaker wires or something. Read the directions again. Check your speakers to make sure they work.
