Hello everybody, i have a mb w202 with some electical problems. It has a bose audio system and after a very rainy day suddenly all my speakers have a "pounch" noise when i power on the headunit. And also the driver door speaker and passanger rear speaker not emitting any sound. I have read from some other post that it might be the ground problem.

Also as soon as i saw the problem went in the trunk tu see the connection to the amplifier, probably when i was removing the coverage of the trunk walls i touch some cabeles and the sound appears in all speakers. Wake up next day the problem came back. On the third day of the problem when the radio was playing i saw that tha front door driver speaker got warm/hot and i disconect it.

To get little bit of presure i disconected the amp connectors so the only power to the speakers come from head unit. I will be very happy if i will jave any advices wjat to do what to check before something got burnned. My email: mir-serioga@mail.ru
