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.
