If you want to beef up the audio system installed in your car, design speakers that are larger than your current system. However, it is possible to design and make a speaker box at home, customized to fit the speaker system of your vehicle. All you need to do is find out the correct dimensions of the speaker as well as amount of space available inside your car. Get the materials required and simply start making your very own speaker box.
To design customer speakers you will need:
- Tape measure
- Carpenter's glue
- Caulking gun
- Wood screws
- Baffle board
- Silicone sealant
- Speaker grill
- Bolts or L-brackets
- Spray adhesive
Fabric or paint
- Measure the dimensions of your speakers installed in your car. Draw a detailed plan of the speaker box. The size of the speaker box would depend on the diameter of the speaker. In case the speaker is of 6 inches diameter, volume of the box would be 0.3 cubic feet. In case has 10 or 12 inches diameter, the make an enclosure having 1.0-1.5 or 5.0-9.0 cubic feet of volume, respectively. Considering these dimensions, the enclosure will be 0.7 x the width deep, where the height will be 1.4 x width. Popularly used shapes for speaker boxes are triangular or rectangular; the shape you choose completely depends on space available inside the car.
- Get a good quality fiberboard to make the speaker box. For instance, particleboard is generally taken for fiberboard which isn't a very good choice as it cannot stand the shocks felt when driving a vehicle. In case particleboard isn’t available, plywood is a great choice.
- Use the plan drawn for drawing the design of your speaker box onto the fiberboard. Cut the individual sections using the jigsaw.
- Cut a hole in the speaker box for the speaker. Make sure the hole made on the front portion is the same dimension as that of the speaker diameter. Make an outline of the edge of your speaker using a pencil, where you want to make the cuts. Make sure it is on the center of the front portion. This can be cut using the jigsaw.
- Apply carpenter's glue on the edges of the cut pieces. Assemble them as per the design. Use wood screws to secure the parts in place. Drill a screw along different joints of the speaker box at a distance of every six inches.
- Take sealant and fill the caulking gun. Apply it onto the joints from the inside of the speaker box. It will make it airtight, thus ensuring good quality audio output.
- Use screws to attach the baffle board onto the front portion of the box. This will make sure that the speaker remains fixed at one place and doesn’t disengage when the car moves. You may also install grill to provide better protection for the speaker system.
- Use polyfill to cover the three adjacent walls on the inside of the speaker box. Polyfill is generally available at the local art and craft store. It will help reduce the mid-bass resonance. Use spray adhesive for spraying it on the wall and simply splash polyfill on the walls to make it stick. Using a drill make a large hole on the bottom portion of your speaker box, big enough for cables to go through from below the box.
- Add finishing touches using different materials. You can cover it using fabric, attaching it with spray adhesive. You can also paint it from the outside in attractive colors.
Tips & Warnings:
- When installing your speaker box, you can attach it directly to your vehicle using bolts or L brackets to provide security.
