Hi all, i am doing a DIY upgrade from my 6 speaker system to the full 10 speaker alpine system with the factory amp. My truck started life as a 2015 tradesman. The only issue I am having is how the factory amp mounts. I may be missing some sort of mounting bracket. The factory amp has a silver mounting plate, but for the life of me I cannot figure out how to orient the amp and what that silver mounting plate screws to. If anyone had a photo of how the factory amp is mounted it would really help me solve my issue.
