I just finished a classic communication install in my 1999 C4. It has a factory amp and CD player. Everything worked previously but since the install the CD player does not work, the two dash speakers do not work, and the sound is terrible. Is there a setting in the pccm+ I need to change to correct this? In the old stereo you had to make sure the aux out was enabled. I have checked all my wiring and even installed the second ground on pin 17 going into the amp as required. I have the setting on the head unit set to amp rather than can. The rear speakers and the door speakers work.
