Where to run amplifier power wire?

[Gorilla Man]

I'm trying to install my subs, but I can't seem to find a suitable place to run the power cable to my amp through the firewall. Can anyone please help me here? I'm gonna go crazy if I don't get some bass real soon! If you have pictures, please post them, or email them to me. That would be really helpful. Thanks everyone.

My rig doesn't have A/C so I just cut out a slot in the blank insert where the A/C pipes run through the firewall, then underneath the carpet, to the back seats and ran the wire in from the side walls of the rear ... its out of site, and works well ...

Use the main wiring harness grommet on the driver side of the center of the firewall (above the accelerator pedal). To get it out easier spray WD40 on it first (just a squirt!)inside the cab, pull the grommet toward the engine, punch a hole in the grommet the same size as your power wire with a leather hole punch and feed the wire through the rubber grommet. Don't forget to put a little dab of silicon sealant around the wire when your finished.
