The factory setup (non dsp) is designed to have x signal coming in which in this case is a higher power amplified signal than say line level. The factory radio even has more raw power out than most of the aftermarket radios speaker level outputs so it normally just works fine.
Thanks Crowz - I know all that - I design audio amps... But clearly the designers of this system had no concern (or understanding) of the basics of maximum power transfer (efficiency) and impedance matching. Power level outputs are a crap way to feed power amps.

But I guess is DOES make for less wiring and more easily configured modular systems and that is more important in auto manufacturing than audio quality....
