How to adjust bass and balance on boxster radio
I just purchased a 2001 Boxster and love it. It has the Porsche CDR 220 radio and CD player. My question is, how do I adjust the bass and balance of the speakers. I hit the button with the notes on it and it says linear. I can barely hear just a little sound coming from the speakers in the door. Did not get a manual for the radio with the car. Any help appreciated.
Thanks,
lew
