I recently purchased a 2004 infiniti fx45 efore i could get it home the left side of the speakers sop playing. It comes and goes. Sometimes sounds muffled. am in love with the sound system up until this point its driving me crazy. does anyone no any solutions to this problem or experienced the same.
Sounds like the wired connection is loose. You'll have to remove the panel to access the speaker, or take it back to where you bought it, any reputable place will fix it for you.
