got some box making questions

First lets convert that to english so that we can understand it. So what you need is a box that is 3.65 cu. ft. Now we can that the cube root (NOT divide by 3, we are in a 3-dimensional space) but I measure in inches. So one more conversion.

Because there are 1728 cubic inches in a cubic foot we multiply and get
3.65 * 1728 = 6307.2, now I don't care about the 7 or the .2, 6300 is close enough

Now we take the cube root of 6300 and get 18.469, so if we round off to 18.5 inches for all the sides we will be close enough to the 103.4 L that you need.

Almost forgot those are inside dimensions if you are using 3/4- inch MDF the outside dimensions will be 20 x 20 x 20.

Sorry about the math leason, but you ask for it

 

Sorry for the English lesson, Ranger lol

 

I am NOT trying to make anyone look like a dumbass. You simply ask a question and I posted an answer. As far as AZN, its his job to correct my spelling and grammer.

Different calculators do cube root differently, cube root is the same as raising a number to (1/3) power. This will get you the answer you need.

As far as conversions, my calculator has built in conversion tables.

MDF is medium Density Fiberboard, available at any Home Depot

 

No one was trying to belittle you. You asked a question, and a very nicely detailed answer was given. If you have issues with that, perhaps another site more to your taste would suit you. We are on here to help folks out, not insult or call anyone a dumbass (well, other than caddy and azn ) We dont get paid for this, we dont get free blowjobs from the local town pump, and we sure as hell dont get any free car audio equipment!!!!

Thank you for your understanding.

 

Basically take the internal dimension (width X height X depth) and divide by 1728(one cubic foot) and you have the internal space.

A 4x8 board of MDF at Lowes is $21.99 More than enough for a normal sized box

 

yes....finding a square root of a number is the same as taking that number ^(1/2)

finding the cubed root is taking that number ^(1/3)

 

All is good my little buddy

 

As for sealing the box, i recomend 100% silicone, color does not matter, just get the cheap stuff. Run a bead on all corners, then smooth it out with your finger tip. (a little goes a long ways)

As for the carpeting..............Well............That just is something that is reeally hard to explain online!!!!!!!!!!!!!!

What I always do is wrap the box with carpet then using a nice SHARP utility knife, over lap the lyers on the back side, then cut through both layers, pull off the excess and there ya go, a nice seam.

as for the other 2, this takes some practice, a pair of carpet shears (scissors) are needed. Cut a peice of carpet a few inchesbigger all the way around then what the box is, then carefully spray glue onto the box and the carpet. heavy on the carpet!!!! apply the carpet to the side and then carefully, holding the shears at a 45 degree angle to the edges, cut away the excess. This is realy something that take s practice to do really good. That is the wya I do it. I suggest using a 3M product for the spray adhesive.

 

Actually thats right, but thats really a big box, how large are these woofers?

Yes you can bolt it to the floor.
