amp wire through firewall

i peeped out under my dash to see if there would be a easy spot to run my 1/0 gauge wire through but dont see anything. i dont mind drilling but right now my charger is lost. the car is a 93 caprice with the 305 not sure if the firewall changed much.

i would like to know where and how did you guys run your wires?

This location on the passenger side worked for me.
Easy access on both sides of the firewall.

Try Harbor Freight. There is a tool for this that makes it easy to go thru any of the holes with rubber inserts without damaging the rubber.

I skipped drilling through the firewall and ran it underneath the car and through the frame then made a hole to come through the trunk with it. I also ran 1/0 gauge, haven't had any issues.

Yes, the lower dash panel on pass side.
This is a good location for a wire to the head unit/dash.
If you're going to the rear of the car, I'm sure there are better routes like under the car as Slim suggested.
