Joe X Posted March 1, 2012 Report Share Posted March 1, 2012 I would try for less deadly alternatives if feasible first, also what car are you placing this in? Quote Link to comment Share on other sites More sharing options...

Joe X Posted March 1, 2012 Report Share Posted March 1, 2012 (edited) I guess you are not factoring in displacements, check this suggestion, is not final or anything, just for you check, also this subs are recommended for up to 33Hz tuning, you barely have the space for them, port/subs front firing: Enclosure Specifications: Fb = 33.8 Hz Vb = 12.628 ft^3 External Height = 28 in External Width = 54 in External Depth = 22.25 in Port Width = 8 1/8 in Cut List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 45 1/8 x 26 1/2 Front Internal = 43 5/8 x 26 1/2 Back = 54 x 26 1/2 Left & Right Sides: Side 1 = 20 3/4 x 26 1/2 Side 2 = 21 1/2 x 26 1/2 Top & Bottom = 54 x 22 1/4 L Port Internal Assembly Parts: Front to Back = 12 5/8 x 26 1/2 Extension = 2 x 26 1/2 Edited March 3, 2012 by Joe X Quote Link to comment Share on other sites More sharing options...
beat2deth Posted March 1, 2012 Report Share Posted March 1, 2012 I would try for less deadly alternatives if feasible first, also what car are you placing this in? its no more deadly than a wall. as long as its got a solid foundation and is secure, there shouldnt be any issue.

A wall could be pretty deadly, I have not heard yet about crash tests on vehicles with walls yet though. Quote Link to comment Share on other sites More sharing options...
