[QUOTE="CheЯRyMan, post: 8327075, member: 662580"] I built a similar box about 3 weeks ago heres a link to thread [URL="http:////forums/miscellaneous-car-audio-reviews/610452-cherryman-custom-enclosures-dual-sundown-sa8v2-crossport-box.html"]http://www.caraudio.com/forums/miscellaneous-car-audio-reviews/610452-cherryman-custom-enclosures-dual-sundown-sa8v2-crossport-box.html[/URL] If you want to use a aero in a straight line you will need a box at least 48 inches long. If you decide to put bends in your aero your efficiency will decline and any advantage gained by using a aero will start to decline. A aero this long will need a considerable amount of internal bracing to hold t up. At these lengths aero's loose their appeal and limit design options over a traditional port. 1.28ft^3 per chamber gross 41" port = .42ft^3. 4x3 Fb=32. F3=28 .78 ft^3. Net volume after all displacements Outside dimensions 43x11hx14.5 deep. [/QUOTE]
