Hey yall! I have an 05 Focus ST that I'm going to install an aftermarket subwoofer in. I already know how to hook it all up but I'm stumped as to where to run my 0 gauge wire into the car. When I had a ZX2, it was automatic and I just drilled through the plate covering the hole of the clutch master cylinder, then ran it underneath the carpet. How have some of you wired your cars? I have no problem drilling holes in the firewall but I want to pick the best spot possible.
