Sound system making a popping noise
Hello, I am new to the forum. I have 2 Mercedes, 2004
ML350 and a 2005 E500. Maybe someone can help me diagnose a
problem that I am having with my sound system in my
ML350 It has the navigation system and the 6 CD changer
in back. Recently the sound system started making a
popping sound and cutting out. Sometimes intermittently
and then it would go completely silent except for the
popping noise. Then later after turning the car off and
then back on again it would work for a little bit and
then start popping again. The navigation stiill works
fine and the interface works switching back and forth
between each function. Also the popping noise continues
even when the system is shut off. The only way that I
stopped it from popping was to disconnect the smaller
top plug of the 2 sets of wires that plug into the
back. I have inspected the plugs to see if there are
any loose wires but they all look good. I also pulled
out the amplifier and checked the plug on that also but
they look OK. I am at a loss now as to where the
problem is. I was thinking the amp was bad since the
noise continued even though the unit was unplugged. any
help would be greatly appreciated.
Thanks,
Tim
