Where to place your subwoofer enclosure can be a difficult question to answer if your trunk is small or filled most of the time. Usually a subwoofer enclosure is a big and bulky box, especially if you're using twin drivers instead of a dual voice coil single driver subwoofer. The sound produced by a subwoofer is known as bass in an audio system. The great thing about bass is that it's omnidirectional and isn't easily blocked by most fabrics. This means you can get creative with enclosure design and sub placement.
Under the Rear Seat
Most cars have seats with big, unused areas underneath them. This means you can build an enclosure to put the subwoofer under a seat. Mounting in this location is fairly easy, because the seat will provide most of the securing and you'll only need a couple of screws and brackets to keep it in place side to side. Just be sure to build the subwoofer enclosure wide enough to have the required amount of internal volume.
Under the Front Seat
Another good place is under the front seat. As long as you build it to fit snugly and have enough internal volume, this is another great place to locate it unobtrusively.
In the Trunk
Most people are going to have a trunk subwoofer. That's because many subwoofer enclosures are actually bigger than they need to be. Open your trunk and look at the area immediately behind the rear seat. If you build your subwoofer enclosure long and tall, but just deep enough that the magnet has clearance, you can fit an enclosure behind the seat and still be able to use most of your trunk space for storage.
Getting the Best Bass
The subwoofer enclosures have a significant impact upon the overall quality of the sound that you hear. If you are looking for the highest level of subwoofer performance, you should plan to do a bit of research before you install your audio system. This will help you to determine exactly which subwoofer enclosure types are best for your particular vehicle and sound system.
Different Types of Subwoofer Enclosures
The two main factors that help to determine what kind of subwoofer enclosure you should have are the materials and the size and shape of the enclosure. Generally, the best enclosures for getting a high quality bass sound are those that feature non-fabric materials. Use enclosures made from plastic for the best results. The best enclosures for bass sound are also those that fit snugly around the subwoofer itself. If there's too much room, the vibrations of the subwoofer can influence the sound of the bass, as the speaker rattles against the enclosure.
- Slanted Subwoofer Enclosure. If you have limited space in the trunk or another part of the car where you're planning on placing the subwoofer, look for a subwoofer enclosure that is slanted. These enclosures make the subwoofer fit into unusual places that it may not have been able to fit into previously
- Wooden Subwoofer Enclosure. A wooden subwoofer enclosure tends to be less expensive than plastic or fabric coated ones. You should be careful, however, that the wood is properly treated and that it cannot let in any moisture or other potentially harmful items. The wood enclosure should also closely cover the subwoofer itself, so that it doesn't begin to rattle around as it produces sound while the audio system is on
The exact type of subwoofer enclosure that will work best for you is also dependent upon the size of the subwoofer that you have, where you wish to locate it in your car, and what type of vehicle you drive. Of course, some subwoofer enclosures are more expensive than others.
