Finished installing the amp and wiring and all is well. The wife is happy and the system has new life.
Tapping in to the factory amp wiring for the speaker level and remote wire connections

There is already a cluster of electronics in the compartment so I won't be installing my amp on that side, plus I think its too big to fit anyways.

Final install pic and I have a coworker cutting the 10" hole in the panel door then I'll install the grill and be done with this project. I ended up placing the amp on the back of the seat for a clean look and ease of adjustment.
