I have a 2004 G35 sport coupe with a stock bose system.

I just noticed an audio problem when I play CD's. This happens with newly purchased CD's from a store, and with CD's that I burn myself (on any computer that I burn them on).

There is low, no, or very muffled audio on both my front and rear driver side speakers.

I turn on the Radio (AM or FM) and the audio sounds the same from left to right, front to rear.

What could be causing this???

 

all I can think of is dirty laser... you can try to use a cd lens cleaner
