Great bass that looks sharp

SPL Boxes' PRO210GMC14VRGB custom-fit enclosure installs under the rear seat of 2014-19 GMC Sierra Crew Cab trucks and holds two 10" shallow-mount subwoofers of your choice. Your subs may be under the seat, but you'll know they're there, thanks to built-in RGB LED lighting that adds a warm glow to your thumping soundtrack. Clear plastic panels in the front of the enclosure show off your subwoofers and lights, while a wireless remote control lets you select colors and display modes.

Built to last

Rugged MDF construction and a tough black vinyl coating mean this box will provide years of service. Inside, polyfill insulation helps reduce resonance for clearer bass reproduction. A raised GMC logo gives your installation a sleek, custom look.

Note: This enclosure only fits Crew Cab trucks; it will not fit Double Cab trucks.
