Hehehe, I like you ;-)

Yes, door speakers are supposed to be sub woofers, but produce little or no output in bass amp mode, but, if I jump two wires off the dash speakers, the door speakers play loud and clear,... but this is not the active bass (sound separation) mode, I think in fact I just by-passed the trunk mounted amp. "Benz" says amplifier failure is very rare and to look elsewhere......any audio people out there?

If it is then check the transistors on both side (they are screwed into the heatsink amp case. One or both of them will show physical damage. If they do then thats your problem. Those transistors heat up and fry. You can either take it in to get it repaired or locate that transistor with the part number thats stamped on it and solder a new one yourself along with a new fuse.
