I have a '97 E300D (210) and wish to know the following:
1: Are there 8 different speaker sites? Two tweeters in upper door at window angle, two front door, two back door and two on top in back of the seats? Are they all single coils or are some dual.
2: How do you get the front covers off of all of them??
3: Can you then remove the speakers from the front without getting behind them??
4: are they all 8 ohm or 4 ohm?

I plan to examine all and consider upgrades. Are there good quality exact fit upgrades? I just don't see much on this subject that deals with 210 model. Thanks in advance.
