H 4 Building an Enclosure Use at least 3/4-inch MDF to build the enclosure (1-inch is preferable). The joints should be liberally glued with carpenter's wood glue and screwed together with wood screws and sealed internally with a bead of silicone rubber or hot melt glue. Drill pilot holes to prevent the wood from splitting and tighten the screws as much as possible. Look, listen, and test for leaks at all joints, around the subwoofer perimeter, and at the wire entrance location. Glue Screws Sealant 5 Locating Subwoofer Enclosure in Vehicle The placement of the enclosure is one of the most important factors concerning installation. As each vehicle's interior acoustics are different, experimentation is the key to optimizing performance. Hatchbacks/Sport Utility Vehicles Locate the enclosure in a rear corner for maximum output. Hatchback Installation Warning Make sure the enclosure is securely mounted in such a way as to not shift or fly forward in the event of an accident or sudden stop. 6 Sedans Provide as clear a path as possible into the cabin by venting through a folded-down arm rest, venting through the rear deck, or venting through an unused speaker opening in the rear deck. Keep any restrictive materials such as wood, hard plastic or metal from directly blocking the subwoofer.
