Help me with tuning

[SilveradoGoesBang]

Hey guys this box is going to be in a extended cab truck with subs foward port up and centered on the back. Its for 4 vvx 15s d2 and would like about 10cubes for them and the box to be tuned to 32hz. Ive been playing with torres and i cant get the tuning to 32 and keep the port area per foot from getting to low. if somone could take a look and help it would be awesome!

Bedtime bump help me lol

if you do port up it will still be an L-port and will end up facing subs you may be better off facing it forwards

also your subs ar 16"OD and will not fit straight across, you can stagger them to fit light so, or like the olympics rings

[john253a]

or you could do port up with 3x 6" aero's 19" long

1" box with either 3/4 or 1 baffle

Okay how much port area per foot should I be looking for?

you know you can go in half and quarter inch increments for the port height and width, right? you dont have to have whole numbers.

edit: you better put some bracing in that box too, or expect it to rip itself apart after a while.

K and im gonna use wooden dowels as bracing just dont have a exact number to put in the box for displacement.

Shit, I go farther than that. If you want to see a number in a box design, you need to make shit precise. For those that are math incompitent.

1/16 .0625

2/16 .125

3/16 .1875

4/16 .25

5/16 .3125

6/16 .375

7/16 .4375

8/16 .5

9/16 .5625

10/16 .625

11/16 .6875

12/16 .75

13/16 .8125

14/16 .875

15/16 .9375

These are each of those little dashes inbetween every inch on tape measure for those that didn't know.

There is no exact number

But a rule of thumb is

Aero 9-13"sq per ft

Squar 12-16"sq per ft

Slot 12-16"sq per ft (9:1 scale or less)
