Bedlined Enclosures

Our bedlined speaker enclosures suit drivers building a clean, durable-looking subwoofer or speaker setup in a car or truck. The textured finish works well in cabins and cargo areas, while sealed and vented designs let you match the box to your sound goals and available space.

Match the enclosure to your subwoofer

Start with the driver size, cutout, mounting depth and required airspace. A subwoofer needs enough clearance behind its mounting surface, and the box must provide the internal volume its manufacturer calls for. Measure the space where the enclosure will sit, including height, width and depth. Account for seat travel, trim and access to other equipment.

For a single 12-inch driver, compare the sealed QBSHALLOW12 DF with the vented QBTRUCK112 VENTED. For two 12-inch drivers, the QBOMB12V is vented, while the QBOMB12 SEALED uses a sealed design. These models make the sealed-versus-ported decision clear: pick the alignment that suits your subwoofer and available space.

Choose sealed or vented for the build

A sealed box uses an enclosed airspace and is often easier to place where space is tight. A vented box uses a port, which needs room to breathe and must stay clear of cargo or upholstery. Match the enclosure's internal volume and tuning requirements to the subwoofer specifications. A mismatch can reduce output or compromise the driver's performance.

• Driver count: Match single- or dual-driver designs to the number of subwoofers you plan to install.
• Mounting depth: Measure from the baffle to the nearest obstruction, including seat structure.
• Airspace: Compare the box's usable volume with the subwoofer manufacturer's recommendation.
• Package contents: Confirm whether the package includes a speaker; an enclosure alone may need a separate driver.

Plan the truck enclosure installation

Truck boxes need careful space checks because seats, floor contours and trim limit placement. Dry-fit the enclosure and make sure its terminals remain accessible. Secure the box so it cannot shift during driving. Keep the port opening unobstructed on vented models, and use a sealed enclosure when its size and volume suit the subwoofer.
