SELECTING AN ENCLOSURE
There are several different enclosure designs for different applications.
The SPL subwoofers work very well in all of the following enclosure

Infinite Baffle
Infinite baffle is the simplest type of subwoofer installation. In this type
of installation, the woofer(s) is mounted to a baffle which is then
mounted to either the rear deck or back seat of the vehicle. The best
results are achieved when the trunk area is virtually airtight and
isolated from the passenger compartment.

Sealed Enclosure
Sealed enclosures are relatively simple to build and install, as all that is
required is an airtight box. The larger the sealed enclosure, the more
the performance resembles that of an infinite baffle installation.
