Enclosure Dimensions 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 contact us at tech-support@soundstream.com, or 1-800-724-1377. Enclosure Construction 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.
