Answers :

First of all check and make sure your fade or balance are not off in the radio settings. if not the problem check speaker connections. If they are door speakers sometimes when closing the doors works the connection loose if this is the problem put a drop of gorrila glue on the connection so it will not come loose. same with all connections where speakers are involved. You can also check the connections on the back of theradio itself.
