Peter, you might want to consider new when replacing speakers. They are still available. I believe the one you want is 944 645 425 00 and Sunset sells it for $92.43 plus shipping.

Jeff, thanks for the part number.
Replacement of all speakers would be the final goal if I decide that the current system is viable. The audio system in my car (originally M490 and 494) was altered by the <acronym title='previous owner'>PO</acronym> in a strange manner: it has an Alpine head, and aftermarket amplifier, bit still has the OEM amplifier under the driver's seat and some speakers are still wired through it. It looks like the job was not complete. Actually it sounds badly, the wiring is pretty bad and the RL speaker is not sounding. My first goal is to troubleshooting the wiring and I thought that an used rear speaker could help me doing that. Depending on the results I will decide to either keep the head and the aftermarket amplifier and replace the speakers with the OEM ones or to go with a completely new solution.
Does anybody has a picture of a rear speaker from a 10 speaker car? The part numbers in the catalog are confusing (with all those available options).
