This answered my question perfectly. I was stumped since my subwoofer harness has 4 wires and the OEM harness on the truck only had 2, but that makes perfect sense. Going to run the cables this week and get it going. Thanks so much for the help.
Hoping this set up will work with the suggestions in this post… I have the 10” Kicker Hideaway sub which is powered. The wiring on the included harness is:
White: Left+
White/Black: Left-
Gray: Right+
Gray/Black: Right-
Wondering what the correct wiring is to connect with the Blue/Gray and Green/Black OEM subwoofer wires.
