There are a few full tutorials on YouTube already, like those from AnubisZed/Dave. This is just a very quick video I took to show how I ran the RCA from the rear to front of the car with minimal trim panel removal or effort. Probably better to run it down the driver's side, I just happen to have all the bottom of the glovebox off already so I went for the path of least resistance and ran it down the passenger side.
