Installed in my 2022 GMC Sierra 2500HD AT4 and it fits, it works very well, and the storage is better than the OE "trough" style storage bin. All jack pieces fit in it and then some without issue. I went with a Skar SVR 12" D2 subwoofer and Skar 1200w amplifier, T-harness w/loc, and an amp rack (ebay). Sounds awesome and I love how the opening in the box points at the back of the cab. It sounds incredible and was exactly what I wanted. The bedliner finish is also a nice touch - rugged, easy to clean, and looks nice.
