Hi guys,

Took wifes car to dinner tonight. When valet pulled it around
after dinner, there was an odd buzzing sound coming from
driver front and rear door speakers. Buzzing and popping sounds
continued the whole drive home with radio on, radio off, cd mode,
sat mode, am/fm mode.

Any ideas on what could be causing this? Did the factory amp
decide to call it quits? Car is 2009 C300 with flip up Nav unit.

Thanks in advance for the help!
