i was wondering if anyone can tell me where my firewall is so i can run my 0 gauge power wire. dont want to drill any holes. If anyone could so me pics that would be awesome.


96 jeep xj sport

Uh...your firewall is between the motor and your dash.

Look up under the dash on the drivers side toward the motor, you'll find plenty of holes there.

theres a rubber plug near the master cyinder atleast on my 89 there is

Personally, I always run 0 gauge underneath the vehicle. Up along the frame rail. Throw some split loom on it too.

OK, so 12 to 14 feet of 0 will carry 250 amps, with some safety..........
Question, is not what it will carry, but what the alternator will output?

Food for thought

Anywhere from 90amps to 200amps depending on what alternator you've got.

Whats your point?

I run a 1800watt amp on 4 gauge wire and its perfectly fine

i have my 8 gauge running under the jeep but i dont like it. because the why i have to get the power wire through a hole near the hatch. im planning on putting my amp on the back seat or on sub box.

its not gonna look good if i have the 0 gauge running from the hatch up to back seat.

sorry if i am being a butt about all this.

I just drilled a hole in the firewall on the passenger side.

Same with me under the heater core

Why not use an existing hole?

Good luck finding one big enough for 0 gauge.... Just drill a hole and stick a grommet in it. Best way to go. Most likely what a shop would do anyways.

I've got some large ones in my firewall.

I didn't see any I could get it through on the passenger side. I didn't want to run the wire to the drivers side. A lot of unneeded wire.

Shouldn't be holes. Modern vehicles firewalls should be sealed up pretty well for safety as gas even finds small holes. If there are large holes someone made mods in the past. 0 gauge wire is freakin huge too. Just a pita if you ask me. I'm running two amps off 4 gauge and it works great. Just drill a hole for that wire and put a grommet in. It's easy to do.
