Congratulations on your new Soundstream sub-woofer purchase. We
greatly appreciate your business. This may look like a run-of-the-mill
cardboard box, but it’s actually a protective barrier over one of the
finest engineered and assembled sub-woofers available.

Soundstream does not provide enclosure dimensions as there are
infinite variables when designing a box, i.e. vehicle, amplifier, music
preferences, etc… For designs tailored to your specific needs, please
Enclosure Dimensions
All enclosures should be made of .75” (3/4”) material only. When
possible, make the baffle 1.5” (1 ½) thick and add .75” (3/4”) to the
depth of the enclosure to compensate. All volumes INCLUDE vent/
port and subwoofer displacements. DO NOT change the volume
unless you plan on adding a substantial amount of bracing. For
added performance, applying a coat of fiberglass resin to the interior
walls will greatly improve sealing the enclosure. Adding a thin layer
of poly-fill will improve response by smoothing out reflections
within the enclosure. Please see last page for woofer wiring diagrams.
