I believe the attached image is my wiring setup. I'm hoping to just do what this fellow did here: http://www.clublexus.com/forums/gs-second-generation/621789-aux-input-for-under-5-00-you-guys-wont-be-disappointed-pic-intensive.html, but I'm confused about the wiring.
In his case, he has clearly labeled CDR+, CDR-, CDL+, CDL- wires into the amp. The ES300 seems to have RearR, RearL, FrontR, FrontL wires as the inputs to the amp. Unless those are little wire bundles with + and - in them... do they just use a common ground? Would I want to then splice in the Right+ to RearR and FrontR, Left+ to RearL and FrontL, then both Right- and Left- just both go to GRND?
Any guidance would be enormously appreciated. It seems like it shouldn't be too complicated...I'm just not great with analog logic..or audio.
