I have searched the forum, but could not find a solution to my issue. I just picked up a 1994 Z28. I have installed several aftermarket radios in the past, but have never encountered this issue. I used a wiring adapter kit, and have double checked all connections.

My new Alpine head unit will work fine on radio mode, however when I select AUX, USB input, or XM radio (built in to alpine) there is no audio? I can hear what sounds like a factory amplifier turn off in the dash when anyone of these settings is selected. The unit stays illuminated, and appears to be functioning, but no audio???

I pulled the head unit and tried it in my Wrangler. It functioned normally.

Can anyone tell me how to overcome this issue in the Z28?
Thank you in advance!

 

Fixed it.
