Hello community, i have R350 2006, couple weeks ago my central speaker started to Buzzz on high volume, or even when i am listening to fox news radio with lower volume. My dealer told me that i have to consider to replace central speaker (~200$) plus labor. Question: does anybody have same issue? How to replace speaker? I don't want to ruin my grill. If it is possible to do it by myself. I think if i will remove central speaker i can find same size and tech. characteristics speaker online. But i don't know how to remove it!

I would take it to a regular stereo shop they know the tricks to replace it. I have a R350 '06 as well and I it has the harman/kardon system from the factory. If yours doesn't have that system (you can plainly see the name on the speakers in the doors if you have it.) If you don't I would replace the center speaker with a harman/kardon.
