While the Audio components are likely available as MB parts, that is simply not the way to go.
Audio parts come in many ways, quality, attributes and price, although the sizes are fairly universal.
Really, you are best taking the car to any auto audio place, even the large chains like Circuit City or such, that have departments that install, have a guy there tell you your options. For what may well be much less than one speaker installed at an MB place, (which is simply a speaker of whatever quality from one of the manufacturers), they will be able to put in a matched set, likely with better performance, or even repair what is wrong fairly simply and for less $. (The wires falling off are not an uncommon problem).
Samsung has an "LN" class with speakers on the front. I've been keeping an eye on the LN19C350 model myself(the number after the LN is the width in inches).

The front speakers are 6.5 in. diameter with a 2 in. depth and the back speakers are 6.5 in. diameter with a 3 in. depth. Pioneerelectronics.com has a system where you choose your make and model, and it will tell you exactly what size your stock speakers are.
there should be four speakers,two in back window of car,two in front on the side lower bottom front next to door panels.
The stock front door speakers on 97- 01 lumina are 5.25 round but the depth of the speaker is an important dimension since the speaker is front mounted in an enclosure which is mounted to the door. I replaced my stock speakers with Sony Xplod model XS-R1342. Any 8 ohm model speaker with similar dimensions will work.
4 inch dual cone are standard

Depending on what year model 1990-1999 is either 6x8 (5x7 is the same thing) or 6.5". The 1996 Ford Ranger XLT model the front and rear speakers are 6x8(5x7).
It depends on the model year but usually the back speakers are 6 x 9 and the front are 5 1/4. Check with Crutchfield.com to be sure.
