I have a 99 Yukon. Currently running 2 Diamond Audio D3 12 dvc in a slotted box with 800wrms Alpine mono amp. I just recently purchased a DA D9 15 dvc 4ohm single sub.

I need some help in dimensions for a good box for this sub. I have read that it will only take a sealed box but I am interested in going with a slotted. Basically I want to go spl rather than sq. If anyone has some dimensions or what not that would be great. I seen the free box section and found one for a slotted box and seems great but will it really matter if it is vented or sealed?

Any information would be appreciated. I have tried re calculator. Realmofex for info also.

I have included the specs below. I hate to bother anyone but I would like to build my own box and see if it comes out good. I have built a box for a 12 in the past and it was decent.

Specs:

SPL - 88

Qms - 3.7

Qes - 0.53

Qts - 0.49

Fs (Hz) - 26

Vas (L) - 75

Cms - 0.100

Mms - 405

Sd (m2) - 0.0785

BL (T.M) - 29

Re (ohm) - 6.2

Xmax (mm) - 26

Znom (series) ohm - 8

Vb - 1.4~3.0

F3 - 40~32

Pe - 1800~800

Qtc - 1.0~0.71

Dimensions:

Bolt Cir. Dia - 14.80"

Outside Dia. - 15.59"

Depth - 9.49"

Thru Hole Dia. - 14.14"

Displacement ft3 - 0.18

Thanks in advance,

Jay
