Power line up the frame rail.
Power line out the door post to the battery.
I bought a Metra kit to tap the power, ground, antenna output and antenna signal at the storage bin behind the pass seat.
Running the speaker wires, RCA wires to the rear.
As you saw previously I ran the 4 guage power wire up the left side of the car and all other wires ran down the right side frame rail into the back. Note: the front left speaker runs down the left side but I kept it way from the power wire as much as possible.
Kind of hard to tell here but the head unit is secure. I used strapping and bent pieces 90 degrees connecting in side to the head unit and the other side to the stock mounting holes.
