Subwoofer Feedback!

This question is not answered

I just bought a new 2017 GMC Sierra 1500 Denali. I got my system installed into it that I had in my old truck (same boss speakers with Nav that's in the new truck). Now I'm getting this really weird feedback humming noise that progressively gets louder. It's happens even when the volume is all the way down. It almost seems to be in sync with the first throttle press. Weird part is it stops immediately when you open any of the 4 doors. I have checked the ground, RCA's, rca converter, remote wire, and even checked the bass knob. It also stops when the bass knob is all the way down as well! I even tried a ground loop isolator. Please please help!!
