I drilled a hole under one of the bundles of cables that run through the firewall and installeda competition gromet. I then ran it underthe carpet as close to the seat rails as I could get it to keep it away from any signal cables that may have been in the side rails. I always try to keep the power wire by its self. I used the same amount of wire as you because i crossed over in the trunk to the passenger side and my power distribution block is mounted in the coner near the passenger taillight.

Edit: My signal wires are run down the center of the car inder the center consel to avoid any interferance.
