RCA's run through right side of the car under the carpet. Also seen is the white cat5 cable I ran along with the RCA's for the remote bass control (RGX) I installed on the lower dash. The cat5 line I ran is not a normal phone cable. This setup uses 2 pair and is non-flipped. This means on one end the color sequence I used is white-blue, blue, white-orange, orange. On the other end it will be orange, white-orange, blue, white-blue....so 1-4, 2-3, 3-2 & 4-1.Along with my iPhone hookup, I also ran composite cables to the front compartment box so the deck will play any audio/video feed you plug in, whether it be portable or a PS3. (wiring in 2x 110v under the seat).
