4 Gauge amp power wire through firewall?
Is there room to put a 4 gauge amp power wire through an existing access grommet in the firewall to the battery, or will I need to drill a new hole?
I have a 2010 coupe.
Also, if it will go through an existing access hole, where would I find it? Is it behind the battery?
Thanks, Randy

2nd pic in post #3 shows what's behind the battery.
Factory cables run through in top left corner of the pic, you can remove the tape and push it through there, or drill a new hole as in the pic.

I simply went through the location for the stock wiring harness behind the battery, it is self sealing. I ran a 4-gauge power and a 4-gauge ground through it. So far the car hasn't exploded so I figure it's ok.
