2018 mazda 3

I just recently got a 2018 mazda 3 Hatchback Grand Touring with the 9 speaker Bose set up. I have a skar md5001d and rockford fosgate P2 10inch. How do I set this up? I know I need a LOC but have never done this. my last set up used a bluetooth receiver with two Ports out, one into the amp one into an aux port on my car
