Anyone know where there is a hole in the firewall for a amp power cable? and whats the biggest gauge u can fit?

 

I'm assuming its in the same place as the evo........on the passenger side down by the floor. I ran 4 gauge all the way to the back.

 

dude, do a search...we just finished this discussion last week...theres a gromet on the passenger side firewall or also if you remove a panel on the drivers side in the engine compartment, there is a spot where stock stuff is run ( i used the gromet, so I don't know too much about the other area)
