Bose speaker only plays on left side of car when playing a cd. when i turn it back to the radio both sides play out equal again. what is the problem and how do i fix this?

hi.sounds like speakers is broken

Take out radio and inspect...tenyrs old

Dirty CD eye. Run cleaning disc.

1. bad radio amp
2. bad wiring to speakers.
3. or bad speakers.

the tests are easy, ask.
my guess is the weak side is bad, the load side is ok.
you can turn the volume down on the load side using volumn control
if yes that side is ok, fix weak side.

ask how, but make sure the wiring in all 4 corners are not damage
and at both ends of harness.

all speakers r connected to the same wires on the radio
If left/right balance and front/rear fader work properly
and sound is coming out it is likely (but not definite) radio is ok and speaker wiring is the issue.
HOWEVER, if it sounds the same on both left and right, it could be the radio. It is unlikely both sides have the same issue at the same time without it being in the radio.
The only way to verify it to disconnect the speaker and substitute a known good speaker.
So back to troubleshooting.

what type of cd it is? try to play another cd ,it could be problem with cd , cause if is problem with stereo system it should happen with radio.

DOES THE RADIO PLAY? HERE ARE THE FACTORY WIRING COLORS FOR THE RADIO HARNESS, RECHECK YOUR WORK. IF U FIND NOTHING THEN IF THE RADIO PLAYS THE CD PLAYER IS DEFECTIVE, IT HAPPENS BELIEVE ME.
