Fiberglass is the only way to really customize your subwoofer box the way you want it to be. Building a fiberglass subwoofer box can take days and the process is laborious, but in the end you get exactly the look you want.
Instructions
1. Build an insert for your subwoofer. MDF is an ideal wood to work with because it's cheap and durable. Build your enclosure so it meets the manufacturer's volume specifications.
2. Determine how you want to aim your subwoofer. This depends on the type of speaker you have as well as how you like it to sound.
3. Position your subwoofer with dowels. Cut and glue them to hold your speaker. This doesn't have to be perfect; it only needs to hold until your first layer of resin dries.
4. Wrap your enclosure in fleece. Make sure you wrap it tightly around the entire enclosure. Apply resin around the fabric. The fabric absorbs the first application of resin, giving you your first glimpse at the form of your fiberglass subwoofer box.
5. Mix your resin so you have enough to create mat layers. This is similar to what you'll see on a boat hull. Apply three to four mats of resin until your subwoofer box is sturdy. Check to make sure it can support your entire body weight to determine if your subwoofer box is sturdy enough to move on.
6. Sand the entire box with 80-grit sandpaper. Apply auto-body filler and sand it again. Apply thin coats of auto-body filler, sanding between each coat, until the surface of the fiberglass subwoofer box is smooth.
7. Remove any loose dowels and install your subwoofer. Finish off your fiberglass subwoofer box with carpet or with paint. If you choose to paint, primer first. Then you can paint it the color of your choice. Lacquer paint is required for this project.
