Those of you who have relocated batteries to the trunk or installed an aftermarket amp. How did you get the cable through the firewall? I'm trying to find an access through the firewall that is big enough for a 1/0 power cable with no luck. Im trying not to drill another hole through the firewall if I don't need to.

Thanks CL!

you are better off going through the gromet that is in the fender well area which is where all other wires go through also. that hole is big enough for 4 0 gauge wires lol and theyre located on both sides

^ what he said.. jack car up, remove plastic lining in wheel well and you will see the grommet.

ran some big wire through there and the air lines for my air ride.

You could just go under the car. Thats what I usually do, I don't like having those thick wires under my carpet. Unless its one of those small amp wire, but 8gauge and lower I would just tie strap it under the car.

I used the passenger side ECU area-trunk cd changer area

I went under the car myself. Then up above the rear subframe and in through an existing grommet in the driver side wheel-well. You can easily fit 0 gauge through there. Less chance of interference from running a big power wire next to any non-shielded cables.

Helpful replies! Thanks guys. I considered going through the fender well area but I couldn't find the access point. I'll need to remove the lining fully.

ive never done it on the sc BUT, when i relocated in my other car i had to add more ground in the motor/engine bay. i was having problems starting the car and dimming lights. just saying if u run into dumb problems like that just remember add more ground from the motor to the engine bay.

and running the wire... what they said...run it thru the gromet in the fender. i have heard of many ppl running into problems when running it under the car. especially when ur car is lowered.

How's that? When I worked at a shop thats how we did all the cars, I always did all my cars like that also. Never had any fire. Hmm. Weird.

if you are lowered and end up scrapping the wire till its raw it will become a open wire then can be grounded to your car either causing a major short of fire

Im pretty sure no one would put the wire under the frame rail, that wouldn't make any sense. You run it next to the frame rail there are a lot of ways to do it. Plus you should put a breaker next to the battery just in case something happens... Like I said, from first had experience in 4+ cars never had a problem with this, its just another option.

What he said...

Otherwise, manufacturers would never put fuel lines under a car, ya know, THOSE fire hazards

D, if you're gonna do all that just UNIBIT the firewall and grommet it properly. What's a more proper way? Punching out a factory wall outlet to half *** some wire through as it hangs in the fenderwell, or UNIBIT'ing the correct size hole and proper rubber or plastic grommet found at your local hardware store?
