Changed radios and...

[masterofyard]

I have a 03 Z71 with the bose system and the Metra gm-OS4. I replaced my alpine unit with a kenwood and now the front speakers do not work. If I by pass the Metra the front speakers work. I have replace the Metra twice with the same result. Any ideas what the problem could be?

Make sure you have the RCAs plugged into the right channels.

I did...when I put the fader to the rear, the rear speakers work, when I put the fader to the front, no sound from the front speakers.
