kl0wn Posted November 14, 2009 Report Share Posted November 14, 2009 User on here made a really good box calculator, ExpoSport. Or you can use RE's box calculator but you have to account for sub displacement, 45s, and bracing yourself Quote 06 Mini Cooper S Sundown, SoundQubed Cadence, XS Power 151s Sealed 155s Outlaw Windshield @ 37hz Link to comment Share on other sites More sharing options...

-Hobby- Posted November 14, 2009 Report Share Posted November 14, 2009 6 cubes net is a good all around box. Tune 36-38hz. Thats straight from the man at AQ. I emailed about this a week ago. He recommends 16 sq in per cube so you need a box 12 cubes berore port and sub displacement and 192 sq in of port. With the dimensions you have up there you are working with 13 cubes gross. The port is going to take up 2.3 cubic feet. Thats a 19 x 10 inch sq port 19 in long, I allowed for 3/4" port walls. Then you need to remove area for displacement. Dont have a number for that but could assume .25 to .35 for each woofer. Your already down to 10.5 to 10.75 net cubes for the box. You might get away with that but you might want to see if you can find some more space. Im building a box for my Ex cab Chevy for those same woofers with the alum coils.
