Need Sub Box BluePrints for 2015 GMC Sierra DoubleCab (2 Sundown 10s" SD-3 Dual 4ohm)


Recommended Posts

I need help with a ported Sub box for my 2015 GMC Sierra Double Cab (Four Door Extended Cab). I would love if someone had blueprints so I can build it myself. If it could be Down firing with the 2 ports facing forward, but I wont be picky.

--Thank You Everyone

MAX size (Front Height 11" , Back Height 7.5" , Depth 16.5" , Width 55")

- Recomended Ported Box Size- 1.0 Cubit Foot per Sub

- I think it should be tuned to 32hz
