How to Build a Subwoofer Enclosure
Adding a new car subwoofer to your stereo system can really enrich the sound quality that you experience in your vehicle. Once you've chosen your subwoofer, you'll need to place it in an enclosure. A subwoofer enclosure provides a box of trapped air for the subwoofer speaker to push against. That air provides resistance for the speaker cone, which lets it vibrate properly to produce deep, rich bass. With a few simple tools, you can put together your own subwoofer box.
