Did you ever get the sub mounted? How difficult was it? I plan to throw a Rockville 12” in mine but oven never done the wiring for a 2018.I am pretty sure Eric has both tunes Trifecta and BNR. I watched his 0-60 on youtube but I will stick with the Trifecta for now. The tune for my 2017 was @ 349 so not as much as the BNR tune and is why I went that way for the canned tune.
My next project is to get this JBL pro slim sub mounted hopefully this weekend.
