Also, if it does not up mix sound, can the audigy 2nx be run off an opus ps since it only requires 5 volts?

Yes, it runs great off a red 5v line from one of the power leads off the OPUS. That is how I have mine setup... I bought a new power plug from Radio Shack to go into the Audigy (so I didn't have to snip the original AC Adaptor plug off) and soldered it directly to a 5v lead of one of the Molex wires (along of course with the corresponding ground as well)...

Same here. I took someone's advice from before and powered my Audigy2 from the Opus. Was very easy and works like a charm.

I'm interested in what wires you used to connect the audigy to the harness. Did you use a mini jack to rca and then some sort of rca to speaker level wire converter?

I took a normal mini stereo to mini stereo wire and cut it in half. Soldered one half to the front pair of speakers and the other half to the rear pair. I bought an aftermarket wiring harness for the ML to do all the wiring so I didn't have to snip off the factory harness...

I simply plugged the mini stereo plugs directly into the Audigy 2 NX into the front and rear jacks... I didn't use any line level converters, everything worked great with direct wiring. I hardwired the Bose amp to a 12v lead off the OPUS to power it. It came out very clean, I have almost zero noise using this setup (just a very minor high pitched whine in between songs with the volume set real high - but very minimal, hardly noticable) Everything sounds great on the Bose speakers using the Audigy, I am pleased how everything turned out after I got it all installed...

Everyone kept telling me the Mercedes Bose systems were all fiber optic and I wouldn't be able to make use of the Bose wiring/amp/speakers... None of that is true, they all work fine with normal copper wiring... I later found after some research that the item that is fiber optic is the 6 disc CD Changer, all the wiring from the head unit to the Changer is 100% fiber... With the new setup, the CD Changer is ancient history now...
