Have Mercedes Questions? Ask a Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question.
Ok, I need to know which audio package yours has in order to know how many speakers and what size they are. I also need to know if yours has an amp or not.
another expert here
the front door speakers a 6.5" (165mm) and so is the subwoofer ( if fitted) under the seat
as to what brand of speaker then I would use either Harman Kardon or Infinity
the Harman site also shows the speaker locations
