2007 M35 Pre amp wiring code

[midnightclub619]

I got 2007 Infiniti m35, 8 speaker Bose amp

I'm trying to hook up an AudioControl LC7i to an amp. I need help with the color code for the pre amp wires before getting to the Bose amp. I have gotten many different versions of Pre Amp speaker wiring diagrams to tap into. I tapped into the pre amp connections but all i'm getting is a hiss out of my speakers so I don't think I have the correct wiring diagram. I have looked up the FSM but it is a little confusing and just need some confirmation bc this is irritating. I also want to hook up a amp for some subs and need to make sure I have the correct color wiring code to make that happen. I've looked endlessly online and need help.

Thanks
