Frequently Asked Questions (FAQ)


This model is CAD-designed to match the floor hump and seat brackets of 2008-2018 Chevy Silverado / GM Sierra Crew Cabs. It avoids the floating look of universal boxes, ensuring the 12" sub has the exact air volume needed without blocking seat latches.
The UBE-GM-08SLVCC-P212 features a ported design tuned for high output. Choose this if you want maximum bass volume and efficiency in your Silverado or Sierra, as the port allows the 12" subs to move more air than a sealed box.
The high-quality black carpet finish can handle minor moisture, but large spills should be cleaned quickly. The MDF wood underneath can swell if water sits on it, so we recommend a rubber floor mat extension to protect the enclosure's base.
No. This enclosure is engineered to allow the 2008-2018 rear bench to fold down and lock completely. You maintain full passenger legroom, though you will lose the open floor storage space directly beneath the seat.
Check that the box is centered over the floor hump. If it shifts during driving, use the included mounting brackets to bolt it to the seat hardware or apply heavy-duty hook-and-loop strips to the bottom to grip the factory truck carpet.
UBE-GM-08SLVCC-P212 is built with 3/4" MDF and reinforced joints to prevent rattling. Even with high-excursion 12-inch subs, the sealed pressure is contained by industrial-grade adhesives, ensuring the box remains airtight and rigid.
Tap the LED controller into a switched 12V source (like the cigarette lighter or an IGN wire) rather than the battery. This ensures the lights only turn on with the truck, and you can control colors via the Bluetooth app.
