I ran the gauge wire throught the firewall on the passenger side,there should be a rubber piece just run through there and you should be fine. Then go under the carpet and back seats thats what I did to mines. I also drilled the amp fuse on top of the fuse box next to the battery.Madmax3 wrote:I just got an amp and want to start the install tomorrow. I am looking for a clean install of the power feed wiring from the battery to the rear of the car. i was thinking of going under to the transmission shift opening and then run under the carpet under rear seat to the rear hatch area. Has anyone done it this way and if not what route did you take with the wiring from the battery to the rear hatch area?
