Where can I find a box design for 2 S12l7 subs (limited space) approx W29xH13xL19 inches can go further on L if needed.Would like to keep it as small as possible to save hatch space.

read the stickies, it really is a lot simpler than most people think

I'm guessin you're going to make it sealed to save on space?

From what I've read sealed is no good for these so I guess ported

sealed is fine. ported is where they really shine.

What are approx outside dimensions of your box

WAY to small for 1 driver ported... maybe to small for both seal (never tried).

The absolute best is 3.25 cu/ft @ 33hz ( with to many boxes to mention in testing )

my buddy has one 12 in 2.5 cubes at 45 hz and it sounds good for daily

w35xh16xL19 any longer on L and I would have to taper could go about 24 on a steep taper after 19

Not too far off from (po2)?

you could go ported with that... single chamber for both with one port to save space

that will work you can do ~ 4cu/ft gross @ 34 Hz and it will do very well.

U wouldn't have a print for that would you?

Would this be optimal for the 15s as well?

6 cubes at 34 for the 15's

4 cu/ft @ 34hz for the 12's & 6 cu/ft @ 34Hz for the 15's would be the low end based on the driver parameters. Maybe another 1 cu/ft for each would be the "ideal" but that all depends on the car.

Looks like W35 X H16 X L23 is the biggest I can go about 6 cubes before port prefer one long port on the top or front over an end port
