How to Make a Fiberglass Subwoofer Box

Step 17 17. Finishing the Box

How you finish the look of your box is up to you, there are several choices you can do. Paint the outside of the box in the color of your choice, add a layer of vinyl over is all, or carpet it to match your interior. For this tutorial I will talk about carpeting because that is what I choose to do. Automotive carpeting should be pretty easy to find, some hardware stores actually sell carpet that is a good match for your interior, just go to your home center and look. For mine, however, I wanted the exact carpet that was used in my car, so I went to the local junk yard and pulled the old carpet interior out of a junked car. Same stuff, you will just need to clean it up a bit. Attaching the carpet to the box is simple, once you have it cut out to fit and have made sure that it does fit, you just need to use some 3M adhesive spray to adhere the carpet to the box.
