2006 Mercedes Benz E350 W211- Add LOC’s and Amp

Hey all, I have a 2006 Mercedes Benz E350 (W211). Car has the standard audio system, Not the Harmon Khardon/Bose 7.1 audio. Being that this car does not have the 7.1 audio, there are no speakers in the back dash, thus no clear area to splice and run to an LOC. I assume that I need to run a splice (to the LOC) from the MOST, since that's the last stop before the speakers, right? I did not want to pull the rear door panels off to run wires back to the trunk for the LOC. Is this the correct solution?? If so, can anyone tell me the wire colors that I need to look for leaving the little MOST box? (I searched the forums and downloads and no info on these cars). Just need a few pointers on how to get this going, if any of you have done one of these before. Sincerely, Innova801

Thank you i am an idiot! I will post pics for any others attempting the same thing. I have seen this done on MBWorld, BenzWorld, but not one where they don't already have a 7.1 and a conveniently placed sub in the back dashboard to pull signal from.
