Well I went ahead and installed the same Alpine KTP-445U following the instructions above and it worked! Sorry no pics I was too busy trying to keep the mess of wires organized.

I decided to go ahead and bridge the amp to 2 channel from the get go so I didn't have to go back and deal with all the crimp connectors if I got some higher wattage speakers.

The whole thing probably only took an hour and a half, most of that was figuring out how to connect the 2 harnesses together for the bridged output, in the car only about 10-15 mins to lay everything out and hook it up. It worked the first try.

Had the gain set to half and I scared myself to death it was so loud, reduced the gain to around 1/4 and it's better but will still need some fine tuning since I think it might be too quiet.

I understand the fruits of my labors (and money) won't truly be realized until I get some new speakers, but so far I'm very pleased, you can definitely tell the door speakers are running much cleaner and clearer than before.
