Is there anywhere on the firewall to get a 0 gauge power cable into the car for amp & woofer installation?

pictures please!

Have a look at the big grommet up behind the throttle pedal. My 4 gauge cable fitted easy, not sure about 0 gauge.

Plus my boost controller is easy to get to there as well

Personally id have put a bit of Sikaflex to seal around those wires, just to make sure no water can enter the cab.

In my car audio install days, i always ran any wires through firewalls so the wire went "up-hill" just before the firewall, this way any water that collects and runs down the wires, will always run away from the rubber gromet instead of feeding water into it.

Britax battery feed studs. Specifically designed to bring battery cables through firewalls.
Part numbers - M46211-01 (Black) & M46211-R (Red)

Much more professional, safer & sealed option than just shoving through a grommet.

Cheers, Liam.

9inch holesaw on the end of a jackhammer?

I used a coat hanger cut down and straightened, and hooked the end of the power cable (which had a fitting for the battery already soldered and clamped on) and just pushed the big grommet near the accelerator, the coast hanger pierced a small hold and went through, then fron the engine bay I pulled the end of the wire through (tight as). Hole is smaller than the wire and tight fit. Mostly water/dust proof I'd say. Took about 2 mins.

Not really water tight though

On my 2005 wagone there is a large grommet high up in the firewall just to the drivers side of centre that is unused (saves poking a extra hole through a already used grommet)

I have also used this grommet, and recently noticed water entering cabin passenger side, traced water to the cables and will be looking at sealing it up.

I don't have amp cables running through there yet but I do have my UHF antenna and the power cables for the car computer running through. Also used the straightened coathanger trick
