Don't know if you have it, but...lift the hood, passenger side, at the back of the valve cover where the firewall has a lg contour to accomidate the long I6 block, there's a grommet I was able to feed a O awg cable through.

And use the seat belt mounts under the back seat, you want your grounds to be as short as possible.

Yea it's a decent ground but better is throwing amp on floor and drilling through floor and still into the frame.

I know this thread is a little old now, but here's the easiest way to put power through a firewall...
Buy (or pilfer) a full length, non-collapsing antenna from some old car in a junk yard. Use a grinder to sharpen one end to a point. Cut your power wire at an angle and tape it to the non-sharpened end of the antenna. Make sure you run the tape up the antenna past the point of the power wire. Coat the tapered area with some kind of lube. Soap water, white lithium grease, professional electricians' lube, etc. poke the pointy end of the antenna through an existing grommet on the driver's side of the engine compartment, slide it down until the lube is on the grommet, go back and forth a couple times, then pull the antenna through from the footwell. It has worked for me on EVERY vehicle for more than 300 amplifier installs. No drilling necessary. The grommet seals around the wire on its own. Drilling complicates things very quickly. I've heard horror stories of drilling into ac lines, through the back of the master cylinder (without noticing until the customer's car could stop - yikes), and others. Again, no need to drill.
