Our dual 10/12 box is great-looking and fits incredible.  Plus, we can fit much larger subs than any other box available...and with more sub to floor clearance than any other box for this truck.  1.75" of clearance is standard on these boxes.   And if that isn't enough already, we also have the new style Silverado logo as an opton.  All these things make Subthump your trusted choice for your new crew cab sub box.
Note: if your sub requires more than 1.75" underneath clearance, you will need a seat lift and shim the box up to compensate.  Our JL12tw3 option has added clearance and is offset with a thin seat lift needed for installation.

I purchased this box for my 2015 silverado crew cab. I paid additional for the black carpet, raised Silverado lettering, and the holes drilled to fit two JL 13.5" 13TW5v2-4 speakers. The quality of the box was fantastic and just running those subs with the stock speakers produces hard hitting bass. I am powering those subs with an Alpine PDX-M12. I'm extremely pleased and I would recommend this sub box to anyone who is considering buying one...
