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.

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.

Flawless ;)

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.

Well, I didn't piddle around with it. After I downloaded it, I read the tutorial over at roe that shows an easy way to work the program, and I design my boxes the same way as I did when I first started. There isn't really an endless amount of skill to obtain when designing boxes with shetchup. You start doing it right and that's just about it.

I wasn't even making fun of the design. I was merely pointing out the fact that it looks somewhat unprofessional/unknowledgeable.

Looking back, I jumped the gun. I didn't know that was his own design. I though he actually paid money for it or something. I hate when I open a thread and my screen jumps to the 8th post or something...makes me think it's the first and I miss half the thread.

My bad. :crap:
