Go through all of that for better headlights, spending money, taking them apart, making them look good etc. but then be lazy with the wiring part of the mod. There is a wire boot toward the middle of the firewall that probably could be used for small wires like that, but if not a simple small hole can drilled through the firewall. In order to put in an audio system with an amp a hole would need to be drilled through the firewall anyway so then at that point those headlight wires could be run with the power wire, and for the most part normally everybody that mods these cars put in after market audio systems anyway. Running wires through the door jam is only going to cause problems.
