GS-TOYCR212

The GS-TOYCR212 is a custom behind-the-seat dual 12-inch sealed subwoofer enclosure built specifically for 2014–2021 Toyota Tundra CrewMax trucks. The biggest buying considerations are mounting depth, available airspace, seat clearance, and whether the customer wants a stealth OEM-style install or maximum output.

The GS-TOYCR212 is one of the more popular Tundra CrewMax truck boxes because it maximizes woofer size while still fitting behind the rear seat. It’s designed as a sealed enclosure, which gives tighter and more accurate bass response compared to many prefab ported truck boxes.
