Shifty-shifty, that's very similar to my set up too! :D

You can't get a signal from the original headunit to go the amp, so he used some converters that go from the rear speakers that turns into an RCA. :)

I have some gizmo's wired to the back of the head unit that send all the relevent wires striaght from the head unit to the amp :)
