just another update to this thread.
I was able to run eNetic's 0awg power wire through the existing hole in the firewall in my 06 canadian sedan. I ran the power wire down the sides of the car, but pushed it under the carpet so it wasn't in the sills. At the driver's seat there is a brace that you can run it under so that it won't bulge near the B pillar.
Just a heads up.
I was able to have it ran front to rear in about 35min or so but I knew what i was doing since I was replacing my 2awg
