does anyone understand the factory bose wiring?

I'm looking at the factory bose amp without onstar, and I see that the wires from 3 out of the 4 rear speakers go into the same plug as what appear to be the power and ground, while the rest of the wires, including the 4th rear speaker, all go into the other plug. Does anyone have a wiring diagram for this amp, or understand what the hell bose was doing?
