Only one speaker work ???
 

Hello everybody

I have a problem with my GMC JIMMY 00 after I install Sony xav-100 I only get sound from front right speaker all other speakers stopped working. I reinstall the factory radio also it is the same problem.

Anyone know how can I solve this problem ?

thank you

That the problem exists with the old radio reinstalled means that that the issue is not the radios. You will have to to a continuity check for all the wires. I'd start first with the plug that connects all of the speaker wires to the radio since that is the one common part of the speaker wiring and where damage to the wiring to those three speakers could have happened at the same time.

The problem solved thank you christine

How did you fix it?

The door wiring harness was loose I try to push both connectors together and it works
