Vehicle conditions, amplifier, music preferences, & other variables make it
difficult to give you exact dimensions for an enclosure deisgn. For enclosure
designs tailored to your specific needs, please contact us at tech-support@
soundstream.com, or 1-800-724-1377. 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 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. Below are recommended enclsoure designs and their expected
performance:
