The speakers on my 1993 190E started having problems some months ago.
First one speaker in the rear cut out, then (a few weeks later) the
second rear speaker, then (a few weeks later) the right front speaker.
With each speaker, the output dropped drastically and sounded very
distorted. Sometimes, I can turn up the volume to almost max and
-bang!- the speaker will suddenly start blasting out sound. I can then
drop the volume to normal and the speaker sounds like it should.
Since the speakers can provide normal output, I presume the problem is
with the radio itself or possibly the wiring. Has anyone else
experienced this behavior? Did replacing the radio solve the problem?
