Very low radio volume ...

Hi



I have a audi a4 1.8t 2000 my radio was fine when I got it but recently the sound was not working anymore so I pulled the radio interface to see if there where something wrong but everything looks good ...



Sometimes when I drive while my radio is ON and reading the CDs without any sound coming from the speakers ( because I still can put CDs and do everything else with the radio ) The sound POP UP ! one shoot maximum level without warning and randomly ... Belive me or not I almost died on the high way because of that cause I got ****** scared I got a reflex ...



Also I can hear Radio very low on the passenger side and CDs very low on the driver side ... (wtf) ...



Anyone know how I can fix that ?



Thanks and hope you can understand what Im trying to explain eheheh ...



++ I got the symphony radio bose option .
