I have installed a 4 channel amp, new door speakers and a sub into my 2012 with the base radio. After searching I cannot find out how to run wires to the new door speakers. They are currently running off of the deck. There is a hard plastic grommet for the wires going to the inside of the door but I don't see how to run a wire through this area. Anyone have pics or a good description of how they ran the wires into the front doors?
