I have a 92 300SE (140 chassis) that the rear door speakers and four rear package tray subwoofers are not working. I am suspecting the rear amplifier behind the back seat. All connections are good and resistance of all speakers is within specs. Has anyone out there had or heard of this problem?

Sopunds like the seven chanel Bose amp that MB no longer supplies. TYhe seven individual amps are always screwing up. There is a place in South Florida that rebuiolds them. Or you can disassemble the amps and replace about 100 capacitors that are usually the problem
