Need Help finding a hole in the firewall

[Tz44]

I'm running some 0ga in my 86 regal and I haven't found a great place to bring the wire through the firewall. I really need a flat spot if possible and it has to be on the driver's side. There's a spot below the steering shaft but that would put the wire pretty close to the steering shaft and I'd rather not have it there. If possible I'd like to drill a hole up high but I'm trying to avoid taking the dash out.

There is a factory grommet with some wires coming out of it that aren't hooked up in my car (the car has had a drivetrain swap and no longer has AC) I'm thinking the wiring is for the factory cruise control or maybe AC stuff.

Thanks for any help

I ran some wires through a rubber grommet just above the stearing shaft.

Yeah I was just looking at that, the guy that did my swap ran all of his wires through there. I planned to re-do his wiring anyway so I might just pull all of that out and drill a new hole for it and run my my 0ga through that hole.

run it under the car and bring it up into the trunk

No question in my mind. Run it under the car. Single ought is big stuff! I assume you are powering an amp so run it to the back of the can and then into the trunk. I have only 4 ga and that is what I did. I can't imagine trying to hide 0ga in the car/under the carpet and trying to get it to bend to fit. The other advantage is now you can run your RCA's wherever and not have to worry about noise.
