Riley Evan Houser Posted May 28, 2012 Report Share Posted May 28, 2012 Alright guys, got another question for all of you, I need some help with this one. If you've read my other posts you'll know that I have 2 Sundown SA15s, but I need help with my new box build. I have roughly 40"s from side to side in my trunk to spare, 19" high, and however deep that is needed. On Sundown's website it say 3-4 cubic feet tuned to 35 hz. What would you guys recommend? But I was wondering about making a box with the 2 subs and one long port under the two? Would I need to add a middle wall between the two or can I just leave it open so they both go out of the same long port under the two? Just let me know what you guys think I should do and how many hzs to tune them at? Let me hear your opinions! Quote Link to comment Share on other sites More sharing options...

carlosg_313 Posted May 28, 2012 Report Share Posted May 28, 2012 should be a decent size box. ill make a design for 7-8 cubes before displacement, and maybe shoot around 6 cuft after displacement tuned to 34-35hz. what amp do you have?

carlosg_313 Posted May 28, 2012 Report Share Posted May 28, 2012 (edited) no bracing? good luck... wouldnt be a problem without bracing. since they are around 70lbs total. ..BUT then again, i will not be builing the box, so you are right. lol. edit - 2x2 can be an option from top to bottom, and wouldnt change much on the internal size and tuning. will be post final sketch in a minute.
