I have bose and put in a pioneer head unit and microvision screen long ago. I ppulled it out this weekend to do some other work in back of the dash, and i plugged it back up and it will not make any sound.

it comes on and playes the cd or radio but it does nto produce any sound. HWta could this be?

thakn in advanced

 

sounds like something pulled apart when you put your dash back together. i'd pull teh dash back out and verify things.
