I just pulled the rear door panels and the rear door speakers, then used some T-tap connectors to run speaker wire from the rear -/+ to the LC2i through the door and then through the rubber wire cable grommet, then down the B Pillar, then along the floor under the door sill plate...all connections are labeled on the LC2i so pretty simple to run the wires...pulled my power from my amp power wire which I ran from the battery through a hole I drilled in the firewall on the passenger side and also ran along the edge of the floor board under the door sill plates.
