Need Help: Putting A 4 Gauge Wire Through A R34 Firewall

[pablo101]

Hi guys,

I'm adding a 4 gauge power wire for my sub, and I've searched everywhere but I can't find a hole big enough to fit it through.

I've already got a 8 gauge going through the same hole as the boost gauge wire but the 8 gauge bearly fitted and the 4 is way thicker.

Has anyone done it before? And how did you do it??

Jack the car up turn or remove the right wheel, remove or loosen the plastic inner guard and route the cable from the engine bay into the rear of the guard and then into the cabin through the large grommet that the main wiring harness runs through.

Do it!

im too lazy for that lol,

ok ill go do it now, but its gonna get dark soon so i better hurry up lol

As Nike would say "just do it" if you're lazy get a cordless and an eff off big drill bit and go nutty!! Swiss cheese that fire wall!

hahaha i was thinking that too, but the drill wouldn't reach.

I opened the guard and I know what to do now, but there is this tight rubber surround thing that I can't get the 4 gauge wire through, should I just cut a hole through it ???

yep just be careful that you don't clip anything else.

Hey guys I did this today and it was much easier then I thought.

I didn't even jack the car up, just turn the wheel.

Again thanks for all your help, really appreciated and without it I would have had no idea what to do

Thanks everyone
