A universal enclosure is sized to a driver. A Vehicle Specific enclosure is sized to a vehicle. Factory cab interiors do not take a generic box cleanly: behind-seat cavities have their own depths, hump heights and panel angles, cargo floors slope, and wheel wells eat into the width. A cabinet that ignores those constraints either will not fit, blocks a factory function such as folding seats or tie-downs, or needs permanent modification to install.
The Vehicle Specific Series is built to the vehicle first. We measure the factory interior, the mounting points and the unused cavity space, then design the cabinet inside those boundaries with an internal volume matched to a driver in the size class the location supports. The result drops into the vehicle, mounts to factory anchor points or sits in a factory cavity, and can be removed to return the interior to stock. Seat travel, recline and fold-down function are hard design constraints, tested during development on the Ford truck fitments in particular.
The construction method follows the install location. Conventional rectangular cabinets are panel-built on dado and V-groove joinery. Tight behind-seat and irregular cavity fits are stack fabricated, horizontal CNC-cut layers of Langboard Elite MDF glued and clamped into one solid block with dowel reinforcement, which is what lets an odd-shaped cabinet stay rigid. Every cabinet is cut on ShopSabre routers in Tullahoma, Tennessee, and finished in plush black carpet only.
Each cabinet ships with polyfill sized to its volume and pre-wired in 12-gauge OFC to the Proline X composite terminal cup, with threaded inserts or T-nuts set for the driver's bolt pattern. Several fitments come as the bare cabinet or loaded with a matched driver; the bare version takes any driver in its size class that fits the cutout, while the loaded version is a single-decision purchase. Passive Radiator Editions add an unpowered cone tuned by the cabinet's internal pressure, extending low-frequency response in the same footprint without a port.
Current fitments cover the Ford F-150 and F-250 Super Duty behind the seat in two generations, 2015-2023 and 2024-2025, which are different cabinets and do not interchange; the Ford Bronco cargo bay with a dual 12 down-firing cabinet; the Ford Maverick; the 2015-2023 Toyota Tacoma; and the 2007-2017 four-door Jeep JK. The lineup expands as new fitments are tooled, and vehicle-specific development is one of the build paths offered for serious projects. Vehicle Specific cabinets carry a two-year limited warranty.
