2014-2018 Silverado/Sierra Double Cab Audio Options

[dazedAndConfused]

Hey all, I feel like I’ve searched the internet high and low and I’m not finding any answers to this particular question. Looks like there’s tons of under seat sub boxes out there for different past and current truck models, but barely any for the 2018 double cabs. Has anyone ever confirmed which custom box variations can fit under the double cab seats, with or without modification? I’ve been looking at Skar for example. I really like their loaded 8” under seat boxes, not a fan of their downward firing under seat boxes. Here’s some examples of what I am asking may fit (not worried about boxes sticking out, it’s not a daily driver anymore).
