Introduction: Sub Woofer Box
Step 1: Tools & Materials
- Table Saw

- Nail Gun
- Wood Glue
- Soldering Iron

- Silicone Caulk
- 2 ea. Front and Back = 15" x 15"

- 2 ea. Top and Bottom = 13 ½" x 13 ½"
Step 2: Planing & Figuring Out the Cubic Feet
Before you start anything, you need to look at the sub you are using. The sub woofer recommends the min. / max. cubic feet for your enclosure.
In this case, I was using a 12" ken-wood and it recommended 0.80-1.50 cubic feet for a sealed and 1.00-2.00 cubic feet for a ported. I chose to go with the sealed box just because it give's you harder bass. (You can pick between a closed or a ported box. A sealed gives you a harder/punchier bass and a ported give you a wider range and can be heard from further distances. Read up more to find the one that best suits you. I listed two sites that can help you find the cubic feet for enclosures.
Step 3: Mark and Cut the Plywood
Once you marked all your pieces you now want to start cutting them out. Once you get to the part with cutting the hole for the sub this can be the hardest part so take your time. I started by making an x corner to corner then drilling a hold inside. Then use a Jig saw to make a rough circle. Once I was done with that I uses a sander shown in the picture. Now your sub should fit inside. After that you can use the nail gun and the wood glue and start putting the box together.
Step 4: Carpeting the Box
I lined the inside edges with the silicone caulk and let it dry. (This can take up to 24 hours to dry completely)
For the carpeting I picked up a roll of gray carpet at Menard's nearby for only $5.00 it was on sale. if you are creating a bigger box you might need more carpet and of course smaller boxes you don't need much. I had enough to cover my box.
I then used 3M spray adhesive I sprayed the backside of the box and then rolling it and flipping the box forward so the adhesive would stick. Do not worry about covering the holes because you can come back later with a razor and cut around the edges giving it a perfect cut.
Step 5: Finish the Enclosure and Install the Sub & Amp
Now that the sub woofer box is completed you can now add your sub. Install the sub and use screws to keep it in place. Then find out were you want to install the amp. Once you find out were you want it you can now use screws to hold it in place as well. Now you have a cheap and easy sub woofer box that cost under $80 Please Enjoy
