help connecting aftermarket sub/amp to STOCK audiophile 9006 headunit!

i'm actually doing the opposite of what most people seem to be doing; instead of installing an aftermarket headunit and hooking it up to the existing audiophile sub/amp, i'm KEEPING the stock headunit, and connecting it to an aftermarket processor (Rockford Fosgate 3sixty.2) then from there, connecting to an aftermarket sub/amp. I'll be completely removing the stock audiophile sub and amp, and just keeping the headunit.

my question is related to how i go about hooking up the audiophile headunit to this aftermarket signal processor. the 3sixty.2 accepts both RCA inputs AND high level (speaker line) inputs. Obviously, ill be connecting the front and rear speakers via the +/- speaker lines coming from the stock audiophile deck.

the only thing i'm confused about is connecting the sub output from the stock audiophile headunit to the 3sixty.2. The 3sixty.2 accepts either a MONO RCA sub input, OR a +/- speaker line input. which should I use? I know that the black/white wire coming from the audiophile harness is the sub positive... is there a sub negative? also, what do I do with the brown/yellow RCA shield wire? Would that even be used? Would that be considered the sub negative?

i've read posts where people used the b/w wire as the positive and spliced it into an rca cable center wire, then connected either the gray/black OR brown/yellow wire to the RCA outer shield... so i'm thinking I could do that, but if the stock headunit is outputting thru high level speaker line outputs, would that even work?

like i mentioned above, I could also try connecting via speaker line inputs instead of using the RCA... but that requires a positive and negative sub connection. I know the positive is the black/white wire, but is there even a negative? would it be the gray/black wire OR the brown/yellow wire? if one of them is actually the sub negative, what would I do with the other one... just leave it disconnected?

anyone who's done this, or anyone who has any advice, chime in!!

I don't know what wire it is specifically.... but you should have three wires. If I'm not mistaken, one will be positive, one negative, and one the remote wire, for turning the unit on and off with the radio.
I've looked at the processor... you can just skip the original sub wiring and run your RCA's from your processor to your amp.

I may not be 100% correct on this info, someone correct me if I'm wrong. Free bump though.

thanks for the reply... i was planning on connecting the processor to the amp voa rca's, as i'm pretty sure the only OUTPUT the 3sixty.2 has on it are rca outs.

i was more confused about the connections from the stock headunit to the processor, not the processor to the amp. :)

just sum the channels the 3sixty.2 should be able to create a sub out from the front and rear high level signal

for some reason, i was under the impression that the audiophile spits out a signal after its been processed by its internal crossover, so low frequencies are cut out of the fronts and rears, so if i were to have the 3sixty.2 sum the fronts and rears to make the sub channel, it would still be missing the actual low frequencies... yes? no?

i wanna say that the front speakers on the audiophile system have the crossover built into the speakers...the rear speakers are just normal 6x8s and the amp for the sub has the crossover built in as well..

ok i started hooking everything up for this setup... i've tapped into the white/black wire from the 9006 headunit for the sub signal (+) and the brown/yellow wire for sub shield (-), and wired both to the sub (+/-) high level inputs on the but i'm getting EXTREMELY low output signal. any ideas?
