Constructing and installing truck subwoofer boxes is similar to building ones for a car. In a truck, there is less space making the job a little more complicated. You need to build a box which fits in the relatively small space in the back of the truck. You will still want the same sound quality as you’d expect in a decent car stereo system. If a box is too small, the quality and volume of the sound will be sacrificed. Constructing your own subwoofer box is a fairly easy task for anyone who has some basic carpentry skills.
Tools and Materials Needed:
- Medium density fiberboard
- Wood glue
- Silicone caulk
- Terminal cup
- Marker pen
- Tape measure
Step 1 – Determine the Best Location for the Subwoofer Box
Space is at a premium in a truck. Unlike in a car, you don’t have a boot where you can put the subwoofer box. In a single cab truck, the best place to install a subwoofer will normally be behind the seats because it is the largest space available. Though it is not ideal, there really isn’t a choice. In extended cab trucks, you may have more space and may be able to install the system behind or beneath the rear seats. Find the largest location in the back of the truck and measure the area.
Step 2 – Determine the Subwoofer Box Size
Take the dimensions for the subwoofer enclosure. First, determine the diameter and the volume of the box. The precise dimensions will also depend on the particular subwoofer you have. You will need to construct a box which fits into the space available. For further details on the size requirements for the subwoofer box, refer to the instruction manual which came with the subwoofer.
Step 3 – Build the Subwoofer Box
To build a subwoofer box, you simply need to build a wooden box following the measurements. Cut the sides, top and bottom of the box out of medium density fiberboard. Using the compass, mark a hole in the front of the box which is appropriately large enough to accommodate the subwoofer. Cut the hole out using the jigsaw.
In the opposite end of the box, there will also need to be a hole for the terminal cup. This is where the connection will run from the subwoofer, connecting it to the amplifier. Ideally, this would be located at the back of the box. Finally, assemble it together using screws and wood glue and seal the seams with silicone caulk. Make sure that the installation is robust becasuse vibrations caused by the subwoofer can cause it to rattle.
Step 4 – Install the Subwoofer Box
Carefully install the subwoofer box and make sure that it is stable in its location. If it is not stable, it will rattle when the speaker system is used.
