In order to achieve the best quality audio output from your car music system, it is really important to understand that the quality of car subwoofers enclosures is every bit as important as the woofer itself. It is important to have the right design for the enclosure to go with the particular woofer that you may choose for your vehicle.

Sometimes it can be difficult to decide which enclosures and which woofers are right for your vehicle. For one, the size limitations of the vehicle and the different sound characteristics of different types of enclosures are two factors that can help you to make up your mind regarding the right choices for your vehicle.

Preferably, the enclosures should be made of MDF, which is, Medium Density Fiberboard, or any other material of equivalent or superior qualities and performance. Secondly, the enclosures must have bracing throughout to ensure that no sound energy is wasted due to flexing. The walls of the enclosures should be lined up with a dampener material such as fiberglass, poly fill, or a tar based spray. This will help to reduce the high frequency resonance.
Woofer enclosures come in different varieties. Some of the basic types of enclosures are as follows:

Angled Enclosures
These enclosures are designed to fit in places where the standard square enclosures cannot fit in.

Bandpass Enclosures
This consists of one sealed and one ported chamber. The sound waves go through the ported chamber, resulting in a loud bass response. This enclosure has excellent power handling and also a good low-frequency response.

Vented Enclosures
This consists of a port that enables the back sound waves to be emitted along with the front sound waves in order to produce a high combined sound output. These vented or ported enclosures are available in various sizes and designs.

Sealed Enclosures
his type of enclosure is designed to prevent the entry or exit of air from the box. It enables the subwoofer to perform with high sound accuracy and tighter bass. Usually, they are available in single, dual, and triple slots.

Vehicle Specific Enclosures
For many different vehicle models, there are also vehicle specific enclosures available readily in the market. You may consult with a good enclosure vendor to review what kind of car subwoofers enclosures might be most suited to your car and your audio system.

If you have smaller space available behind the vehicle seat or in the trunk, you can use shallow mount enclosures to match with shallow mount subwoofers. There are also hatch box sealed enclosures that are designed to save space.
