box design help

[CleanSierra]

well i like aeros . (i cant get a slotted port right) and i know its a differant truck but im my ext cab s10 i had, i had the subs facing forward for awhile and then up for awhile. facing forward sounded better to me

With a cut sheet, a slotted port certainly is easy, and probably the route I would choose.

i would do i slot if i could get the dimensions right. im just not good with port area and all that. i built 4 boxes for my sa12 before i said fuck it and did a aero

[CleanSierra]

For slot port, box would be:

W-39" H-20" D-20"

Port H-18.5" W-4.5" L-21"

.34 for sub displacement(none for bracing at the moment)

Net airspace would be just at 6(5.96) tune at 35Hz(34.96) 13.97 sq inches of port per foot.

[CleanSierra]

If aeros box dims:

H-20" W-37" D-20"

5 4" aeros at full length if 17 inches

10.50 sq inches of port pert foot

5.98 cubes of air net

34.67Hz tune

shit so i will have to do 15's

[ToNasty]

those dimensions are for a single 18 correct? because if i can keep it at one 18 i have room to the side for my amps and b attery

[CleanSierra]

The dimensions I gave are based on what you gave. You said 5-6 cubes, I really don't know what subs you're building or if what size they are at this point. I'm thinking you don't have the subs yet. I was only going off of dimensions you gave. What will go in there is up to you. It looks like its the proper space for 2 15s. 1 18" would fit in the space also, yes.

Once you decide what you really want to do, then ask the questions you're asking now. Are you actually ready to build? Like are you just contemplating getting custom subs or are they actually being built?

[CleanSierra]

The max dims you listed won't be enough for 2 18s. Even at 54" in width that only gives you 10.40 before port and sub displacements

[ToNasty]

yes your correct. i am ready to build and i like the dimensions you gave me for 1 18. that will work a lot better then to actually fill my whole back seat and have to squeeze an amp and battery in. the dim you gave me for the 1 18 will allow me to fit everythingi need

I say try to get 2 in there
