I ran my power wire through the firewall on my '07 sedan today. It was similair to the amp install in the "how to section", but slightly different, so I thought I would post this.
What I found easiest to do was remove the knee panel and the lower kick panel from the driver side. Take them all the way out so you can get room to move and work under the dash.
After these are out you can see where the hood release cable goes through the firewall. Now, just to the upper left of that cable you can feel around behind the rubber matting in that area to where most of the interior wiring goes through a large grommet into the engine bay. Basically I just cut a large piece of that rubber matting out (because after you put the kick panel back you cant see it anyway) and made it super easy to reach up and feel the large bundle of wires and that large grommet with my fingers. I felt up in there with a utility blade, made an incision in the grommet, and easily ran the power wire through. This grommet is not hard at all. The consistency reminds me of a pair of nitrile gloves. Easy cut and easy to run the wire through.
Because this area is high up on the firewall I didn't see a need to seal the incision with silicone or anything else. I wouldn't think water getting in here would be a problem, If anybody feels differently about that, please let me know. And if you think pictures would help with this, I could try and work on that too.
