I just ran across this thread while searching for something else. Sorry I didn't see this back when you started it.
For the amp turn-on, you could also have tapped into the Red wire on that combined forward/reverse I made for you.
I remember we had talked about using the pin on the Navi's harness intended for the remote-on for the OEM sub. When you found that your harness already had a wire there I forgot to suggest building the combined harness with the red wire "broken" too.
I've recently heard from someone that the power antenna wire (pin 14) on the Forester/Impreza Navi is 'on' whenever the HU is on, so that pin may also work for an amp remote-on.
