SMS Precision Ford F-150 Underseat Subwoofer Enclosure Builder

SMS Precision Ford F-150 Underseat Subwoofer Enclosure Builder

The SMS Precision Ford F-150 Underseat Subwoofer Enclosure is a built-to-order bass solution for 2009 and newer Ford F-150 Crew Cab trucks. This product is for customers who want clean underseat fitment, stronger bass planning, and a custom enclosure path instead of a loose prefab box that was not planned around the truck.

Fitment: Built for 2009 and newer Ford F-150 Crew Cab applications. This enclosure requires a 2.5-inch seat lift. Fitment should be confirmed before production, especially if the truck has rear underseat storage, aftermarket seat hardware, unusual trim panels, or other interior changes.

Select the base finish and subwoofer layout first, then add paid custom build upgrades like 45-degree corners, LED acrylic plaque, LED rings, high-power terminal, aero ports, pre-wired OFC terminal, and wood engraving.

Base Selections

• Model: 2009+ Ford F-150 Crew Cab, requires 2.5-inch seat lift
• Finish: Bare Wood, Carpeted, Bed Lined, or Vinyl Face
• Subwoofer Layout: 4x8, 2x8, 2x10, 2x6.5, 4x6.5, or 6x6.5
