ok so last week something weird happened. i'm riding down the freeway bumpin the phatbox and i realize that it sounds a little funny. when i listen closely, only my right speakers are working. i try and adjust the balance and turn it all the way left... NO SOUND. so i thought it was the speakers but when i hit the radio button, all speakers work. Somehow the phatbox stopped sending audio to my left speakers. can anybody help figuring out whats wrong or what i could do to fix this?
