Is there any way to get through the firewall on a 2004 monte? I have to run a few wires to the battery but I can't find anywhere to get through!

 

There is a write up by RobH68CHevy about installing an amp and subs and he shows where he ran the wires thru the firewall.

Hope this helps.

 

I think he wants a method minus drilling.

 

Pick up the passenger side carpet by the center console. You will see a wire harness that goes through the firewall. There is a rubber boot around it. You can use a stiff hanger to punch a hole through the boot. That will let you get through.
