I will be installing an amp soon for my Alpine Type-R 10". I have taken a look at the stock sub wiring on my '09 tC and have seen yellow, white, blue, purple, pink, orange and black wires connecting to the stock amp. From what i have figured out from the wiring diagram is this:
Yellow: RL -
White: RR-
Blue FR- OR B+
Purple: FL-
Pink: FL+
Orange: Antenna Amplifier

My amp has high and low level imputs (Profile California AP1000M). I wanted to know if I could unplug the stock sub and tap these wires for imput and remote instead of tapping from the HU (Stock HU). If I can tap these wires from the stock sub which ones would I tap? My goal is to not take apart the center to get to the HU, for various reasons. Also, if these cannot be tapped and I have to tap the rear speakers, do I use T-taps or just straight connectors?
Thanks for helping,
