Hi. I need help in identifying the factory radio wires in my 2001 Suburban (with OnStar and Factory subwoofer). I am adding an aftermarket amplifier (Rockford Fosgate 301S) to power an additional subwoofer (8" Rockford in a Q logic Q Form which fits under the front console).  I have checked with www.installdr.com regarding the radio wiring diagram however after removing the factory radio,  their  wire colors and wiring diagram don't match with my car (probably because I have OnStar and a factory subwoofer). I need help in identifying the following  1.  what color is the switched 12V wire? (to turn on amplifier).      2.  What colors are the rear speaker wires (i need them for a highlevel input (through a line out converter) since the factory radio doesn't have  preamp outputs.  3. Do i really need a LOC for this project?   Any help would realy be appreciated.  Thank you.
