Hello I have a 2007 honda pilot and am putting in a new stereo but can't figure out what the 3rd plug is for? Is it for the trunk subwoofer?
You must add a small amp for the rear subwoofer and use audio cables that plug to the back of the head unit and it goes to the new amp and hook speaker wires to amp
Please be more specific. What car trim (Navigation or not), what model head unit, and the harness model.
I got an 2008EX AWD call crutchfeild or go online they even have the steering wheel controller adapter and the wiring harness so yo don’t cut any wires it’s clean and get rid of the factory subwoofer just look at the difference it’s like having a little house party just enough thump lol
