Hey guys, my Nissan Titan 2004 model's rear audio just stopped working. Even as i turn the fader all the way to rear it fails to produce any form of sound. The front head unit is the Rockford Fosgate AM/FM radio w/in-dash 6-disc CD changer. Anyone have this happen to them or know what I should do to try and fix it? Also I know the rear system is supposed to work because I just recently installed Eclipse subs in the rear portion of my Titan. (If you are wondering the rear audio, meaning everything, was working for about 2-3 weeks before this problem.) Thanks ya'll.
