gt58 Posted July 25, 2012 Report Share Posted July 25, 2012 ok so my buddy picked up a skar ivx 12. those subs get low so were trying to build a box to low 30's. i stumbled across EXO's video and he suggested the RE AUDIO box calculator. so after measuring out his trunk in the audi a4 we came up that we could go no more that 33inces wide and 17 inches tall. we want some room to slide it in so the length and height we played with. this is what we came up with. keep in mind i have never designed a sub before. tell me what you guys think. oh yeah skar recommends 2-2.5 cubes for this sub.

BobbyG2 Posted July 25, 2012 Report Share Posted July 25, 2012 The RE audio calculator works, but most here recommend the Torres Box Calculator pinned in this forum. Apparently it's more accurate. *New vehicle and system coming soon.* Link to comment Share on other sites More sharing options...

OB/GYN Kenobi Posted July 25, 2012 Report Share Posted July 25, 2012 The port area on that looks way to small, but I am on my phone, so can't see the dimensions so I could be wrong. 05 Cadillac Escalade ESV Platinum Bumping the stock 9 Speaker Bose FTL...

321slapinbass Posted July 28, 2012 Report Share Posted July 28, 2012 try 16in^2 of port per cube. your box is 2.5 cubes so 2.5 x 16 = 40. so a total of 40in^2. your port should be 3in x 13in to get 39in^2 of port 2000 Dodge Durango Subs - (2) SKAR VVX 15 D2's Box - 7.2 ft^3 @ 33hz, 120 in of port Sub amp - Digital Designs M2 @ .5 ohm Mids + Highs - PRV Audio Mids + Highs amp - Hifonics 2000.4 Headunit - Alpine CDE-100 Equalizer - Clarion EQS746 Batteries - Mopar group 27 + (2) C&D 52ah Wiring - 1/0 BIG 3, (2) runs 1/0 Alternator - Singer 250A 147.79 dB @ 35hz - burp - sealed on dash 147.47 dB @ 35hz - music - sealed on dash YOUTUBE: http://www.youtube.com/user/321slapinBass/videos Link to comment Share on other sites More sharing options...
Ddub847 Posted July 28, 2012 Report Share Posted July 28, 2012 ya i think your port was a little on the small side plus did you add displacement for subwoofer and bracing Link to comment Share on other sites More sharing options...
Joe X Posted July 28, 2012 Report Share Posted July 28, 2012 Here is a suggestion, port area is more than enough: Enclosure Specifications: Fb = 32 Hz Vb = 2.4 ft^3 External Height = 14.5 in External Width = 31.5 in External Depth = 16 in Port Width = 2 5/8 in Cut Sheet List: * All Dimensions in Inches. * Wood Thickness is 3/4 for all Parts. External Enclosure Parts: Front = 28 1/8 x 13 Back = 31 1/2 x 13 Left & Right Sides: Side 1 = 14 1/2 x 13 Side 2 = 15 1/4 x 13 Top & Bottom = 31 1/2 x 16 L Port Internal Assembly Parts: Front to Back = 11 7/8 x 13 Extension = 15 1/4 x 13 Assembly guide (generic dimensions) Link to comment Share on other sites More sharing options...
