4-gauge power wire?

[millrtime]

got rid of my old system about a year ago and missed the bass too much, so im buying another smaller one from my cousin soon. the amp kit that he has includes a 4-gauge power wire and i was just wondering if there was any place in the firewall to run it through. a couple of my buddies had to get a new amp kit because their cars wouldnt allow a 4 gauge, just wondering if cavy's were different. thanx

god damn, not knowing alot about this, ive gotta ask, how thick is that??? almost sounds thicker then the cable going to the starter...

1/4" i think. now that i actually think about it, im almost certain im gonna have to get a smaller wire.

There's a large grey grommet going through the firewall on the drivers side, near the master cylinder, (may need to raise out the air intake box to see it well, I don't recall..) On the inside it comes in to the left of the steering wheel boot.
