What the hell was Bose thinking!
Ok I KNOW this subject has been beaten to death but after doing some research on the audio faq and finally finding what the Bose amp puts out I was actually rather shocked to find out the rear speakers are driven MONO from the Bose amp on the C6.
So for you audiophiles out there I am assuming Bose was trying to get fancy with their sound stage by driving rears mono and center front channel but why would you want rear to be mono. You think they thought by leaving it stereo it was going to screw up sound stage or was it one of those:hmmm its cheaper if we drive it mono... ? just odd configuration given it also means that they are driving the rear as a 2 ohm load... almost makes me want to use those wires for the sub amp ;-)
At least I now know why the rear speakers sound so crappy... just havent found a good theory or explanation why Bose would drive rear mono... anyone care to theorize?

Going to a 4 channel amp and separating the rear speakers left and right will fix this soundstage corruption (along with permanently disconnecting the center dash speaker which is also mono). However, you're left with the task of filling that hole in the frequency response by changing out the door speakers for full range 3 way systems.

By the way, Dolby Surround, the passive-matrix surround system where surround information is extracted by subtracting left channel from right and sent to the back, and Dolby Pro Logic, long the standard in active-matrix surround processing, both have/had monaural back channels, with a bandwidth limit of 7 kHz.
It would be nice to have analog Pro Logic II in a car, because it processes two discrete full-range back channels. And with much faster attack-and-release times in the control voltages of the steering logic, imaging is much better with no audible artifacts.
(Jim Fosgate invented Pro Logic II, and I was his national sales manager for four years. The guy is an icon.)

You'll notice that instruments (such as the piano) seem to change position on the soundstage as they shift from high notes to lower ones. This is why.
