DIY Truck Subwoofer Enclosures
- 1). Measure the space inside your truck to determine the size of the subwoofer enclosure.
- 2). Develop a cut list of parts. The sides will butt-joint into the top, bottom, front and back. The top, bottom, front and back will need to be cut 1 1/2 inches smaller in width than the overall box width. The sides will be cut the depth and width you want the box. For example, if you want a box that is 12 inches tall by 12 inches deep by 24 inches, the two sides would be 12 inches by 12 inches. The top, bottom, front and back would be 12 inches by 22 1/2 inches.
- 3). Draw the pieces needed on a sheet of graph paper to determine the amount of material needed. Medium density fiberboard (MDF) is often used to build subwoofer enclosures. These sheets are available in 4-foot-by-8-foot sheets at your local home improvement store.
- 4). Measure and mark lines onto the MDF sheet. Draw straight lines where the pieces need to be cut using a straightedge and a pencil.
- 5). Cut the pieces out using a circular saw. Mark the pieces as top, bottom, side, front and back with a pencil to help aid assembly of the box.
- 6). Place the top, bottom, front and back against one of the sides. Screw the sides to the parts using a power drill and 1 1/4-inch grabber screws. Assemble the remaining side and fasten it using screws and a power drill.
- 7). Place the cardboard subwoofer template that came with your subwoofer onto the front of the enclosure. Draw a line around the exterior of the template on the enclosure with a pencil.
- 8). Cut out the box for the speaker opening with a jigsaw.
- 9). Place the subwoofer into the hole in the enclosure. Fasten the subwoofer using the screws that came with the kit and a power drill. The screws are placed around the exterior of the subwoofer.
