In the Si with Premium sound (I am told), there are four (front L/R, rear L/R) outputs in +/- format (differential balanced line level) that feed the external OEM amplifier (in the center console I think?) which splits off the separate subwoofer channel and I think possibly separate lines for the tweeters also.

Bypassing the factory amp to go direct to processor then to amps should "on paper" yeild the best fidelity, but not all amps or processors will have the appropriate balanced inputs to accept it.. JL, Rockford, Kicker, etc do as far as amps, but wondering about what folks have actually found with the 3sixty processors.

Yes, that PXE-H650 unit has had mixed reviews but looks like a great great processor... If it can appropriate take the head unit signals, it would be ideal as it has the right amount of output channels.

I should expand and see who's had what outcomes possitive or negative with either the 3sixty.2 or the PXE-H650 then, from head unit output rather than amp output.
