2010 Sedan right speaker not working [solved]
 

Originally it was working fine then sometimes it would just not work, and then other times it would. Also have experienced it turning on in the middle of a drive. Now the speaker does not turn on, the only thing I could add to this is my battery is old as ****.

A single speaker only sometimes working has absolutely nothing to do with the cars battery. You should be checking for loose connections at the speaker or head unit. Could also be a failing head unit or speaker.
