I got in the car this afternoon to go for a little driver and after about 20 mins I realize that there was no sound? I thought maybe I just had teh volume turned all the way down, but it turns out no matter how the volume is adjusted there is no music or nothing. The cd player or head unit itself is working but no volume? This is just weird, I turned up the amplifier a few days ago but have had no problems until now. I last drove it friday and it sat all day saturday, everything was working fine until today when I realized out of nowhere there's no sound. Anyone have any clues?
