How do i wire through firewall 2003 pontiac vibe?

I don't think he really answered your question, and well, it's been months since you asked, but basically the idea is to find the firewall penetrations that have already been made by the manufacturer in running wires through the firewall for the steering column, power windows, etc. Your owner's manual should help point out these places, but actually feeding the amp power cable through it is very challenging. If you know somebody that has already done it before, they will be of much more help than... me.

I have a 2004 Pontiac Vibe and When I picked up my wiring kit for my amp I also picked up gromets for the 4 gauge wire I used but I'm sure they come in other sizes as well.... Sound Domain was where I picked them up.... Good Luck
