I have 2 Illusion Audio Im-12 Shallow Mount Subwoofers which i want to install in my Suzuki notchback.
Here's how one of them looks in the car:
I intend to mount the second one in the boot. But my concern is any lack of documentation with the subwoofer, thus not allowing me to have an idea about the exact specs & dimensions of the enclosure it needs.
the present enclosure measures about 1.5 cu. ft. and i really don't know if i should mount the second sub on the same enclosure with an mdf partition to provide each sub with their air space. (hence alloting them .75 cuft. each: is that enough?)
the boot measures about 350 Litres, if you need that kind of data.
I dont need the subs to go loud. I just want the bass to be tight and musical, without sounding muddy or muffled, or having that boomy nature.
my system is tuned for SQ. i like it that way.
These are my requirements. Can someone help me design an enclosure accommodating the 2 subwoofers? a modification to the present one seen in the picture will be preferred.
Cheers in advance!

You probably have these T/S parameters. :: i l l u s i o n a u d i o ::
If you are concerned about the exact measurements for your particular driver, unless you are doing ported and the factory specs are way off you should be okay for modeling.
Depends if you like the sound of your sub as is, then '1' should be okay. However, when I run 2 of your subs for isobaric through the calculator I get
.95 cuft w/ a Qtc of .7.
Again, not sure of the perfromace gain going isobaric, but box size reduction is apparent at the expense of complexity and depth of box.
