Trying to add an additional amplifier and subwoofer to the pilot for some more bass. When adding the line out converter, I noticed that there is a selection of wires to choose from. The instructions obviously say to add the rear left and right speakers, but on my Acura TL, I added it to the stock subwoofer and was wondering if I could do the same? When reviewing AllData on the wiring diagram, I noticed I have the following:

SUBW+
SUBW R SP+
SUBW-
SUBW R SP-

Question is which one(s) do I tap into? Also, this is on the “Tuner-Amplifer” and I am actually unsure if I have the “Stereo Amplifier” but if I did, not sure where it would be.

-Not so important question- Also, do I need to remove part of the dash to disable the ANC due to feedback?
