I have a 2000 Mustang
GT that is in terms of audio equipment, pretty much stock. The previous owner installed a different head unit (Sony CDX-F5710) to allow iPod use, but other than that, nothing else.
The problem is that sometimes, the driver side speakers stop speaking, or become very very quiet (adjusting fader settings confirms this). Most times, the solution is to turn the volume up very loud, and that returns sound to the driver side speakers, but only for a few minutes. I checked briefly the connections behind the head unit and the speakers but they seem pretty good. I'll check them again tomorrow.
Any ideas what could be causing this or how to fix it?
