my box builder told me i will be getting about 3 cubic feet per sub( im doin 4), but when i entered tha dimensions on this

http://www.rockfordfosgate.com/rftech/box_wizard.asp

it only shows 9 cubic feet...and that aint even with port.

my dimensions for tha box are 38w x 20h x 26d - and he usin 1"MDF.

i can call him back and go up to 24 inches in height....but i dont want to if that Rockford calculator is incorrect.

hmm.. box seems kind of small

 

[WOT]

Thats 9 cubic feet EXACTLY. I wouldnt trust that builder!!

Use this calc

Ps 9 cubes is to small for 4 15's ported. I got 16ish after displacements and I wanted more!!!

how on earth did he gt 12 lol

get a good design from some one here and build it your self

would be cheaper $5-15 pay pal for design plus material

and you will gain all that valuable experience

( get design and take it to a builder ) just make sure he follows it

I had him up it to 24 inches height.

BTW im runnin 12's so i only need 2 cubic feet each sub.

And I planned to build it but now its to late, i posted a thread requesting a design and cutsheet on caraudioclassifieds a week ago and no1 came through. im tryna get it done by this upcomin weekend cuz theres a car show.

Not a very visually appealing design. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

how did your 1st sketch up look??

 

[Ayy 10+ year member]

port length is 21.5 inches ( im guessing) and tuning is 35hz

and yeah this is tha first box i ever designed so thats why it dont look that great.

I'm just saying, I don't know if I'd want a box design from someone who can't make their design look professional, or like they know what they're doing. I'm not saying it isn't a good design, just giving my opinion on what kind of first impression it gives. Not to mention, not all of the dimensions are there and it looks like it's missing some separation lines in order to make the layout of the MDF make sense.
