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:
