does anyone know where the holes in the firewall are so I can run a 4 guage amp wire thru? i cant find a stickie or post for this.

 

Welcome to DF JB.
Do you have an I4 manual or auto or V6?
If you have a V6 and don't mind drilling a hole, you can go through the firewall right behind the strut tower and next to the brake resevoir. That's where I drilled for my 0 gauge...or you can try and get to the wire harness boot on the passenger side. That one is tough though because of the motor being right there, but if you remove the plenum, you may be able to get to it...same with the I4 manual, only because the master cylinder is in the spot that is blank for the V6's.
