For example, one 10-inch subwoofer typically requires an enclosure with 1 to 1.5 cubic feet of internal volume for optimum performance, while a 12-inch subwoofer requires 2 to 3 cubic feet. The space available will dictate the size and shape of the enclosure, which in turn will narrow your choice of drivers. If you own a hatchback, for example, calculate the cubic footage of the hatch area, keeping in mind that youll still need access to your spare tire. The first step when designing an enclosure is determining how much space is available in your vehicle. Other virtues of the vented design include better reproduction of low bass, a reasonably flat response curve, and low distortion – provided the box is properly constructed. Vented boxes are more efficient than their sealed counterparts, since they channel sound waves from the front and rear of the cone into the listening environment.

Vented enclosures – also known as ported or bass-reflex systems – are more complex than sealed boxes, but the extra construction work required to install a vent has its rewards. Superb damping, good power-handling capability, and simplicity of construction make the sealed-box enclosure an ideal candidate for a variety of installations. This improves bass response, since opposing waves can cancel each other out when they arent isolated. When a woofer is installed in one, the sound waves that emanate from the front of the speaker cone are separated from the rear-firing waves. Straightforward in design, the sealed box is nothing more than an airtight enclosure whose purpose is to enhance speaker performance. But before you grab a saw and carpenters square, you have to decide which box will best suit your needs. Two enclosure types that are practical for most automobile applications are the "sealed box" and the "vented box." Although different in design and operation, both types utilize the same basic construction techniques.

The box-building option is regularly exercised by enthusiasts in pursuit of smooth, deep bass – a tough nut to crack in the automobile environment. While each aspect of system design brings a unique set of challenges to the installation party, building custom speaker enclosures is perhaps the most creative aspect of the installers job.
And the more exotic the install, the tougher the task. Cramming electronics and speakers into places they simply werent meant to be presents a challenge to even the most savvy of installers. Lets face it: Installing car stereo equipment is no picnic. Originally appeared in the May/June 1989 issue of Car Stereo Review magazine.
