Quick Question About Drilling Through Firewall

Hey guys,

Installing an amp/head unit/sub into a friend's car and I was hoping you could give me a little guidance as to where the best place would be to drill throught the firewall, on the passenger side.

I also need to know if the gas tank is right under the trunk since I want to secure the box in place with some l brackets . . . and I certaily don't want to drill into something like the gas tank.

Thanks!

Rtyska, if you look on the firewall, there is an eyelet somewhere on the driver's side. It goes through the firewall - lots of wires are run through there, and you should be able to run your wire through there.

And yes, the gas tank is underneath the trunk. I wouldn't reccomend drilling through it. If you were to design the bracket so that it could be attached in the wheel well area though, that would work.

I found an opening below the glovebox which worked well for 4 gauge wire. Just be sure to silicone around the wire.
