    Step 1: Measure the Area where you Want to Install the 12” Subwoofer Enclosure

    You will want to measure the area where you are going to install the 12” subwoofer enclosure. Use a scale or a measuring tape for the purpose.

    You will need to make 100% sure that you take the measurements perfectly, as they are what will lay out the design of your subwoofer enclosure. Take height, width, and depth measurements, and take them precisely.

    Step 2: Use an Enclosure Calculator to Design Your 12” Subwoofer Enclosures

    There are calculators out there that will design the 12” subwoofer enclosure the right way. All you have to do is enter the dimensions for your enclosures. Here is a web site that you can use to make the calculations the right way http://www.carstereo.com/help/Articles.cfm .

    This web site has about every imaginable calculator there is, you should be able to find exactly what you need to do the job the right way here, but make sure that your calculation are for dual subwoofers.

    Step 3: Lay Out the Design of Your 12” Subwoofer Enclosure

    You should have all of the measurements that you need; now you can lay out the design on the ply wood. Since you have calculated the design for your 12” subwoofer enclosure, you should have bought the proper amount of ply wood, and other supplies to do the job. You absolutely have to be able to draw long straight guide lines to follow as you cut the wood.

    Step 4: Cut the Wood for Your 12” Subwoofer Enclosure 
    It’s time to get to the cutting. You can begin the cutting of the ply wood now. You will need to follow your layout with laser precision. You cannot afford to cut inside the lines or outside the lines. If either one of these things happen, it will throw your design off. It is best to mark the boards with pencil so that you do not get confused which panel goes where.

    Here you wil not only be cutting the panel sides, but also the subwoofer hole and terminal cup hole. Make the cup hole with a drill machine. When drilling, insert the jigsaw tip inside the hole. Now, using a compass, make a circle with 12 inches diameter. Ensure to place the compass in the middle of the front panel.

    Step 6: Put the 12” Subwoofer Enclosure Together  

    Here you will put the wood that you cut in the step together by attaching all three sides. Take the hot glue gun and run a small bead of glue along the edge of the wood you put together. Drill three holes on each of the three sides. Insert the counter sinking wood screws and fasten the panels.  Now, After that you can drill your pilot holes and screw the wood together. Let it dry and your enclosure will be ready.
