Wire routing through the firewall

On my friends 1g we are trying to put a system in it but I am hesatent to drill a hole in the firewall. Any gromets that I could use or does anyone have a pic of where to drill?

Even drilling its hard to find a way to get through the firewall. Its a double firewall, and with the dash installed its hard to get a drill up high enough to get over the K member. There are only two place I bother running wires through. The steering boot on the drivers side, or the engine harness boot on the passenger side. Just poke a hole in the rubber and pull the wire through with a smaller wire or a screwdriver, etc.

i just installed a couple of subs in my car, the best way i found was on the pasenger side of the car. theirs a prity big rubber boot their that you can use a big screw driver to punch a hole through it and then fish your wire through. take out your batery also it makes it alot easyer to reach the boot.

Yes, that is the engine harness boot.

I have all my wiring going through the passenger side. All wires are in a blue loom that reaches all the way to inside the compartment, that allows to add more wire later easily, without having to repoke the rubber.

haha yeah i just cut some of the pastic away from that passenger side hole (so its not as waterproof...oh well...=P )
