HELP! Can't find a hole big enough for 0 gauge wire

[SnoopySLR]

I plan on putting a second battery in the inside of my car. I have 0 gauge wire to run power from the alternator to it, but I can't find a way to get it through the fire wall. Anyone have 0 gauge wire for their system? I really need to finish this project. I want my car finished (except for the engine )by the time I pull it out of storage. Thanks guys!

Drill right through the upper firewall on the drivers side

by the washer fluid? I was hoping I could do it with out drilling, or is that impossible.

I had to drill to get my 4 gauge in.

Right around where the washer fluid is fine, just stick your hand up under the dash to make sure there are no wires in that area, there shouldnt be, but its always good to check first.

There is no way you can go without drilling to get a wire that size through the firewall. ^^^^^ like he said, just go through on the upper drivers side corner and you'll be fine.

...not too sure about an N/T, but I fit mine through the main factory wire grommet.
