Rear audio stopped working....

[Physh1]

Stock system (bose) except for the head unit which is a Pioneer 4200 & everything has worked great since day 1. Just a few days ago I noticed no output from my rear speakers. I pulled out my head unit & everything looks fine.

What else can I look for & is this something common? Any advice?

More than likely the back speakers are shot very common on older gm. If it isn't the speakers it's the factory amplifier.

if all the back speakers went out then i'd suspect the amp. can you plug the factory stereo back in to verify???
