Best way to run 0 gauge through firewall?

[BFeezy 10+ year member]

I have a 2000 Ford Taurus and I'm trying to run 0 gauge through the firewall... I can't find any holes big enough to run the wire through... should I just drill a hole? Is there a better way?

Thanks

Drill a hole or go through the factory grommets by poking a hole in the grommet

on most fords you'll have to drill a hole and use your own grommet.

1. Drill hole with step bit

2. Put 0 gauge grommet

3. Run wire

4. Silicone

(P.S.) I have 4 runs of 0 gauge through my firewall.

So would advice to run it under the car and come up at the amps location.
