CallMeTy Posted May 31, 2009 Report Share Posted May 31, 2009 this is for two FI BL 15s ok. im trying to get a rough estimate. fi's website says is should be between 2.8 - 4 cu^ft. and tuned between 28-37hz. lets just make it a simple 3cu^ft and tuned to 30hz(if this part matter, i dont know) what size box (roughly) am i looking at for two 15's? hope this makes sense Quote 1999 Altima 5spd HU: Alpine CDA-9887 Frnts: CDT audio 6.5 Components Rears: Alpine Type R 6.5 Components Speaker Amp: DAT HR4125 Subs: 2 AQ HDC3 15's coming soon Sub Amps:(2)US MD2D Wiring: Stinger Link to comment Share on other sites More sharing options...

sully Posted May 31, 2009 Report Share Posted May 31, 2009 prob going to end up being around 40wx16hx22d depending on the port size to get around 6cuft after displacement using .75 mdf. add more if you put excessive bracing inside the box. sub up port back to make it work.

CallMeTy Posted May 31, 2009 Author Report Share Posted May 31, 2009 sub up port back to make it work. this means the subs would be facing up towards the trunk lid and the ports would be in the back of the box facing the seats correct?
