How to Make Truck Subwoofer Enclosures How to Make Truck Subwoofer Enclosures
Unlike in a car, there is relatively little space in the back of a truck for a subwoofer enclosure. Making truck subwoofer enclosures requires a somewhat different approach to making one for a car. They need to fit in a small space and maintain a good level of sound quality. If the volume of the subwoofer enclosure is too small, then the quality of the sound, though it may still be good, will not reach the same sound level without distortion. Building your own subwoofer truck enclosure is not a particularly complicated task for somebody who has basic carpentry skills.
Step 1 – Find a Location for the Subwoofer Enclosure
The first thing to do is find the best location for the installation of the subwoofer. In a single cab truck they will typically be installed behind the seats. In the case of extended cab trucks, you can install the subwoofer behind or underneath the rear seats. Find the largest suitable location and take the appropriate measurements to determine what size box you can build.
Step 2 – Measure the Dimensions for the Enclosure
Once you have taken the measurements, you will need to get an accurate calculation for the size of the subwoofer. Determine the diameter, and internal volume requirements and depth. The exact dimensions will depend on you particular subwoofer. Refer to the instruction manual that came with it for further details.
Step 3 – Cut the Sections of the Enclosure
Once you have the dimensions lined out on a piece of fiberboard, you are then ready to start cutting the sections. Cut the six panels for the sides, top and bottom of the box and label each piece. You will then need to cut a hole in the front panel of the enclosure where you will install the subwoofer itself. Use the compass to cut out a hole of the right size, according to the diameter of your subwoofer. Use a jigsaw for this job. You will also need to have a hole for the terminal cup. This is the connection point where the subwoofer connects to the amplifier and is normally located in the back of the box.
Step 4 – Putting it all Together
Connect the six panels that you have created to form a box. Use glue on each seam and then fasten them together with screws. The connections need to be very tight and secure. If there are any loose connections, the vibrations caused by the subwoofer will cause the enclosure to rattle. You will also need to seal the inside seams using silicone caulking, to add insulation and make for a higher quality listening experience. Allow the box to dry overnight before you use it. Then, make sure that it is secure and strong enough to hold all of the materials that you will put into the box.
