need help building a subwoofer box for my subs

[Siikdude]

hi there.. so i have 4 x skar zvxv2 d2 subs and i have a jeep wrangler 10' the max diamentions in m jeep is a width 42in x length 26 1/2in would like less like 23 length or less if possible to have some space in my jeep, and the height i can do max 17in or i can do a Wedge Enclosures that measures 18 1/2in length max by 42 width max by back height max 25in and front height max 17in. i have some some models of what i was thinking. but i believe it has to much volume in it ill post it btw i like to listen to trap, rap, dubstep, house music, hiphop, edm

drivers recommendation is as followed by skar audio
Recommended Enclosure Specifications
Recommended Port Area 38.0 in² ,
Recommended Ported Volume 3.00 ft³
,Sealed Volume Not Recommended
Recommended Tuning Frequency 34 Hz

Subwoofer Measurements
Total Height 11.39"
Mounting Depth 9.89"
Magnet Diameter 7.85"
Cut-out Diameter 11.25"
Outside Diameter 12.62"

T/S Parameters
Bl- 21.8 n/a, Fs 44.0 Hz, Re Dual 2 Ω, Sd 510.0 cm2, Cms 0.04 mm/N ,Mms 341.0 gr, Qes 0.50, Qms 6.10, Qts 0.45. Vas 25.6 L. Nref 0.15%. Xmax 29 mm (one-way), Sensitvity 83.7 dB

box max dementions
24 length x 42 width x 25 height back panel with front panel 17 height, or 17 height max
volume displacement of my 4 subs should be 33.84 liters im not 100% sure on this.

this was my initial idea, and the middle has plexiglass.

pictures are in link below

This thread... lol

Here is an example of an enclosure for 4 of those subs. This would fit an Escalade SUV and its braced just enough to get away with single ply .75" with a double baffle.

This would definitely save time and money. Nice design.

Op... even if you use an aeroport, single ply construction and sacrifice a goat, Those measurements just won't give enough airspace. 4 12's take space... those are not sealed box subs and the displacement of the port in addition to everything else will be considerable. That pic I posted has almost 3ft3 of displacements I had to factor in just to get the net airspace.

the max diamentions in m jeep is a width 42in x length 26 1/2in would like less like 23 length or less if possible to have some space in my jeep, and the height i can do max 17in

Here's this ^^^^ single ply, double baffle...

That design I posted is for a full size SUV.

Here's what it measures out to...

Lol thank you all for the help I'm going to start making a 3d model of it.. If that top model works then I'll just use those bracing that fit my enclosure if not I'm going to go with one similar to the one he mentioned.. Here's the Pic of the ones on talkin

I just figured out the bracing like the one in the picture and the Cu ft it will take up in my box. The only think I'm missing is the port displacement I have no idea how to calculate.. My port size will be 28W by 5.75H.. Should be close enough to 160 Sq in. And my port length says it should be 20.80 inches.. Would make 20.75 inch instead.

Port will take up 1.93 cubic feet.

Does everything on here looks good?.
Should look like the bracing in the sample above

Is that an excel spreadsheet you made?

Umm yeah the braces should look like the one for the Escalade.. Edited!!! Sorry that's all wrong... I can make the box 12. - 12.15 Vb correct? Edited.. So i made a 3d model of it. Had to move some things around.. Here's the specs of the box.. If someone could check the Cu ft of the bracings and the port.. Minus the wood for the port.. I'll provide all the measurements here in a bit aswell.. Tight now what's left after displacements is 12.55 I can lower that two 12.15 or 12.. Which ever is better or what u guys thing would be better. Just let me know

 

[Siikdude]

Okay guys iv got it. I believe I'm all set .. Here's a picture of the internal volume enclosure. Along with the specs and all the bracing inside and port.. The port is at the back upper panel. It's inbewteen my seats headrest so it's not choked off..and the bracing will be window and the sides perhaps windows aswell. If u guys see anything wrong or incorrect on the spreadsheet. Plz let me know I'll appreciate it. And thanks for everyone's help!

Looks good, gonna be fun to build no doubt. Are you using some sort of CAD software or a specific box design software?

What’s the tuning frequency

 

[Siikdude]

What’s the tuning frequency

I have it set to 34hz

I'm using sketchup.. And im inputting the measurements of everything by hand.. And setting everything up.. Right now I'm placing the wood pieces over the internal volume model I had... Then imma place all the individual pieces on a 4x8 layout and see how many sheets I need

Pretty cool stuff. Are you using the free version?

Pretty cool stuff. Are you using the free version?

Yeah I am.. Ill probably end up hacking it. So I wont have to pay

 

[Siikdude]

Yes u can use the web version of it.. Its free

 

[Siikdude]

Can i get build build the enclosure With standard Birch 3/4 plywood? Rather than Baltic Birch plywood?.. I have bracing aswell it will be window bacxing and 45s in each corner of the box except the 2 small enclosures in the sides.

 

[Doxquzme Premium Member]

Yes, any good quality Birch or other furniture grade ply is fine. it has to be furniture/finish grade and preferably 13 ply.

Yeah 13 ply is 3/4 right?
