Corolla LE 1998 Amp Power Wiring

[vseth]

I've got a Toyota Corolla LE 1998. Just got an 4 guage amp wiring installation kit, and now need to get to the battery through the firewall, and prefer to not drill any new holes through the firewall. Would prefer going through existing grommets, if possible. On the passenger side in the trunk, i did notice about a two inch cutout hole in the metal with some wiring coming out. Tried fishing my way back from this opening with no luck. If somebody's done an amp install on their corolla, you input is appreciated.

No Corolla here, but are you wiring from back to front? It's easier to wire from front to back, at least I think so, and run the cable along the door sill panels. From the front, you can always take the DRIVER front wheel well panel off, with the wheel off, and fish the cable through the existing grommet. That's the best location since you don't need to stretch the power cable across the engine bay since the battery is on the driver's side. If you just try and look for places to snake, it won't happen easily.

The two inch cutout hole that I was referring to in my post is actually in the passenger side in the Engine Bay, I'd mistakenly mentioned it as "passenger side in the trunk". Are there options other than removing the wheel well cover, for running the 4 Guage from the battery through the firewall.

There might be, look for where the steering column comes in from the engine bay. My friend ran his 4-gauge power through the rubber grommet there in his '00 Camry.

I have a 1997 Corolla. If I'm going to go through the driver side grommet (the open hole he referred to...), should I open the wheel well? I'd like to go through the center grommet, but it seems like it's sealed on the external (hood) side. Any advice?
