There should be a rubber boot with wires already going thru it on the passenger side firewall. I don't think you are going to get anything bigger than 8 gauge thru it. I ran my power wire thru a drilled hole about two inches from the rubber boot.

You could run it on the drivers side, there's a grommet over there that should take 1/0, but it'd be kinda rediculous since the battery is on the passenger side.

So where did you run it through? Could help others in the future.

I ran my 1/0 cable down the wheelhouse (or whatever you prefer to call it) to the frame, and then along the frame rail next to the fuel line to the back of the car where I put it through the floorpan via a grommet. Where it passed near the engine and exhaust I ran it through some heat resistant cloth like what you'd use on spark plug wires/boots.

Since the 1/0 gauge is fairly stiff, I found it much easier to run this way than trying to conceal it under the carpet and make the tight bends that'd required. Plus, it eliminates any EMI issues that may arise from running the power cable near the interconnects or speaker wiring. Plus, should it ever need to be upsized (however unlikely) I can do so without pulling any of the interior - only the floor of the trunk will need to be removed.

kinda convoluted... under the wiper cowl.. behind the door hinges.. through a new selaed grommet.. behing the pcm (thats a ****ing bitch and a half!!! I was wiring in my new component set too...) and then under the carpet... It all clears any moving parts and fits without any sign... somehow

This is kinda temp... Ill be rewiring the car again in a few months... probably a coupla runs of 1/0... or maybe 4 runs of 4 (so much easier to work with)...

I only have 8gauge right now but when I rewire I will up grade to 4.
Right now Ihave mine ran down the wheel well, zip tied up under the frame and drilled hole under the rear seat, using a gromet and than into the trunk.
I will be doing the same with the 4 gauge except I will drill a hole in the trunk floor instead.
I did this like 5yrs ago, it didnt make any sense to me to try running inside under the carpet when you have to keep it away from RCA and stuff. I cant believe more people havent done it this way.
Later
