ok ok ok............think I've got the final plan in place.........basically instead of installing the audio system in my RAM while on vacation I hung cabinets in the garage and painted it while I did more RAM specific audio research...........hopefully this will minimize snags.
After much reading, several emails, online detective work, and some testing..........here is the plan as I believe it will work:
HU = Stock RA2 U-Connect 5.0
Kicker KSC 3.5" coaxials in the dash under stock HU power
Kicker KSC 6x9 coaxials in the rear lower B Pillars under stock HU power
So the difference here is I'm going to run the KSC 6x9's physically in the rear speaker location but receiving the signal from the front speaker output that would normally power the front door 6x9 speakers. I will in effect just leave the rear speakers disconnected.
I verified today that disconnecting the rear speakers does not inhibit the signal to the four front speakers......that's a good thing because that will allow me to run the Audio Control LC2i prior to the factory 3.5/6x9 split without the need to run "add-on" resistors (theory)
From there I will run two sets of RCA outputs from the LC2i. One set to the Pioneer 8601 mono amp powering a Sundown SA-10 subwoofer. The second set of RCA's will go to a Pioneer 8604 4channel amp powering some Pioneer TS-D1720C 6.75-Inch components.
And that should do it
