how many sheets of mdf would i need for a 4.25 to 4.5 cu ft box for two 12's and 2 cu ft per chamber and a 30hz tune going to build a box tomorrow so please let me know asap

[pro-rabbit 64]

Likely around 1-2 depending on sizes of the pieces needed.

[grumby13 3]

the longest piece(s) i believe will be 32 or 31 inchs

I was able to get 5.3 cubes for my 2 12s but if I screwed up I would need another sheet. Get 2 so you don't have to waste gas if you need another one. The wood won't go bad if you keep it in a dry area

[grumby13 3]

so the longest is 38x16 and i need 3 of that length so i can use 1 whole one and a few others

[grumby13 3]

would there be anything wrong for have each chamber have there own port or should i have both subs use one port and where can i get terminal cups. and what is a good way to seal the cups

[grumby13 3]

i will post all the specs for each piece

Box Bottom plate: 38 x 16
Box Top Plate: 38 x 16
Box left Plate : 15.25 x 14.5 x 15.25 x 14.5
Box Right plate: 14.5 x 14.5 x 14.5 x 14.5
Box Front Plate: 33.25 x 14.5
Box Back Plate: 38 x 14.5
Port L1: 12.5 x 14.5 x 12.5 x 14.5
Port L2: 1 x 14.5

3/4 x 48 x 96

I would just get 2 to be on the safe side.

Keep them same chamber it'll give the subs more space.

You don't need terminal cups. Drill a hole and have the wire go through and seal it with caulk.

You might want to use a more reliable calculator then RE Box calculator.

Should give you a general idea of what you need. If you only need a little more than one full sheet you can pick up 2'x4' mdf sheets at home depot for like 10 bucks.

damn 4 cubes in a camry? i want to see this. im sure it will fit no problem but my 3 cubes with my ported box is big and wide. it was a pain carrying it downstairs to my car. luckily it was easy to put in the trunk. like stated before you dont need to go all fancy. you can drill a hole for the wires and then silicon it up. i got my box design from another source.

[grumby13 3]

just built the box i will add some pictures to this so you guys can see. it came out to 3.853cu ft. i have to see how to add picture to this page/forum. i went with a hole in the back i think i will add a rubber grommet that will not let or let a very little air through
