Our new Large single downfire with amp space fits just like our other boxes for this truck. What we did is integrate our amp box and dual box into one. So we have one large chamber for sub volume, along with an amp shelf. Everything else stays the same as our other boxes. We still have 1.75" of clearance underneath and the overall width the the same as our dual box. We trimmed out the amp shelf so that once the seats are folded down, the amp is not visible. But the openness at the rear leaves airflow for cooling. We also installed a convenient speaker terminal connection right next to the amp shelf. If that isn't enough already, we also offer the Silverado logo as an opton. All these things make Subthump your trusted choice for your new crew cab sub box.
