Ok. I have one 12" L7 in 3.4 Cu tuned to around 30hz. I want to buy a another L7 and run both at 1ohm to my 1500D. So, I want around 3-3.5cu ft after displacement per chamber tuned to around 31hz. Should I have a seperate chamber for each L7 with seperate ports? Or one Large chamber with one slot port? Or maybe I can try some aeros.

Anyways, these are my max dimesions. 34" wide, 14" high and 56" depth. (yea i know, 14" high) I built the box I have now, it's been amazing, but I want more bass.

Should I use aero's? Or slotted ports?

What is the website you all use to calculate the dimesions again?

Thanks. Does anyone design box btw?

you have plenty of space:

11.5ft^3 @ 31Hz w/103in^2 of port!

i don't know how much port you want, but this might work:

but a large single chamber box like that would need lots of bracing!

Oh sorry.

I meant 6-7cubes total. So 3-3.5 per chamber.

yeah, i know

Oh, thats my trunk space. It's more than that. The back (where seats) 1/3 is 14" high, the rest from the back to the front (taillights) is like 20" high. It's just this overhang thing that protects the rear speakers from the trunk I guess.


ok...umm this is what I came up with.
