Help running power and speaker wire

[Dtowncats 10+ year member]

Today I gutted the interior in my 92 Mustang hatchback. My plan is to run 1/0 to the hatch into a distro. For the power wire, where can I run the power wire through the firewall? I looked but I didn't see any unused grommets? If I should drill a new hole where should I drill it? For the speaker wire, I want to run speaker wire to each of the doors from the amp in the hatch. How can I route the wire from the hatch to the doors? Do I have to remove the dash?

Look again... almost all cars have unused grommets, maybe one of them only has a tiny wire going through it, and u can use the same hole to run your wires.

And doors have a piece of rubber tubing that runs wires from your door jamb to your doors, you're going to have to pull it through there to run it through the door, which will involve taking the door panel off and some interior panels (not too hard). On my driver's side door, I couldnt get it through though, and I just ran it alongside the rubber tube, which seems to be fine.

My 1/0 is ran through the frame and comes up in the back cargo area. No problems with trying to put it out of sight through the car.

you can do that or you can cut into a grommet that has a wire in it and run your wire threw an existing grommet that is already being used. but becareful not to cut to close to any of the wires. the only bad thing about running it under your car is if any of it shows or can be touched it could get snagged on something like a speed bump, ect
