I believe this unit IS actually original to the car. I recall looking at the car and finding the CODE document thing in the manual booklet thing. I'll have to find where I put it and everything.

If the Active Bass systems run off of speaker level inputs, its likely that it runs off the rear speaker lines. Since my rear speakers aren't working, theres nothing to kick the active bass system on.. Perhaps the fader has died somehow.

In other MB's the amplifiers serviced one half of the vehicle (front/rear left or front/rear right) I don't believe BOTH rear halves would be out. It must be a signal problem upstream. Perhaps at the do-nothing fader. Maybe it crapped out and someone bypassed it ****tily.
