I have a 1993 300TE (wagon) and cannot find information on the type/size of speakers I have. All the info I can find is for sedans.

I have the stock speakers (2 in front dash and 2 in rear doors) plus the bass boosters (or whatever MB called them) in the lower part of the front doors. Everthing in the car is stock, including the stereo.

Does anyone know the specs on these speakers or can direct me to the right place? I am planning a complete replacement/upgrade of the system.
