It's in!!! I got the amp installed today, minus the remote turn on wire. I had to buy a low voltage trigger and I didn't get a chance to install that today but that should go in tomorrow.
I still need to finish my sub box, and I'm gonna do that today. Aside from my horror story with getting the power wire through the grommet, everything else has gone very smoothly. I never figured out what those couple crow's feet things were for though...
I can't thank everyone enough, and I promise to do a real writeup to collect all the information in this post into a how to for others to read.
Thanks again (pics comming soon).
