I have a 2013 Honda accord and im installing my two JL audio 12' subs and im using a LC2i (Line output converter) i was able to pull the factory stereo and tap into the 12 volt power wire to use as a remote and i was able to run the wire to the back of the car. now this is where im confused the LC2i has a ground input, 12+ input and a remote in and a remote out. Which one do i connect that same power wire i tapped into?? do i connect to the 12+ or the remove in ?? please help.
