I am looking for the location of the rear speaker wires under the dash, under the seats, or behind the sill kick plates. I have the 2.4L with the base radio. I am looking to amplify the rear speakers that I have upgraded. I already know the colors which are Brown and Yellow for the drivers side rear and Gray and Tan for the passenger side rear. These are the same colors used for 2015 and older although the 2015 and older these wires go to the amp under the dash on the drivers side while on a 2016 and 2017 they seem to go directly to the radio. Last resort is to pull the radio and tap in there but I want to avoid this. I plan on mounting a small amp on the metal plate under the steering column. I have a 2016 Equinox but guessing its the same for Terrain and also for 2017.
