Speakers going bad on 300m -> known problem?

One or two of the speakers in my '00 300m are going bad - they buzz at
certain frequencies. I think it's the speaker mounted to the front door
near the windshield.

Is this known to happen with this car?

I suppose I'll have to take it apart and see if I can get an aftermarket
replacement.

 

I've replaced both radio/control unit, and speakers in a couple of
cars I've had. Always had good quality from www.crutchfield.com.
The wiring harnesses match up perfectly and the fit is just like
factory.

 

After 10 years, it's a known issue with car audio speakers -- regardless
of the car.
