I recently purchased the Pioneer DEH-P4001HD head unit for my car, and had it professionally installed. After the installation, I tried to make sure everything was working. The radio and hd radio worked - all 4 speakers had sound. When I tried to play a cd or play my iPod - only the right front/back speakers worked.
Would there be a setting I accidently set where sound only comes out of the right speakers when playing anything but the radio?
I don't know much about car audio systems...I appologize in advance. I'm not very familiar with car audio systems.
Thanks.
