I have 01 Catera, I'm wanting to install a sub and amp. Does anyone know where to run the 12v positive from the rear to the batter? Such as any openings in the firewall.

Not gonna work right !!!! U can burn everything around. U have to wire positive right from battery !!!! Negative u can attach to the body any where in your trunk. Run it on spare side , find drain hole for rain and run it from there under your car to the battery, to run to battery u can use hole right where your brake lines at by driver side tire, easy to find

I would strongly suggest running all wiring INSIDE the car.
