I have a 2003 Elantra. I'm trying to get a 6 gauge wire ran through the firewall to connect an AMP in the trunk to the battery.
I'm having trouble finding a place to poke through. There is a place near the brake wire where I could probably poke through, but that would exit me behind the brake booster, which is somewhat tight. I could remove the computer and poke through, but the computer is attached somewhat wierd. There is some sort of epoxy attaching it to the firewall and the firewall is cut and re-welded there, so I am a bit concerned about that. Anywhere else, and I'm looking at removing a lot more than I care to, afaik.
Anyone care to share how they went through the firewall? Thanks.
