newbie looking for kicker L7 box design advice

[buickv6]

I have done some searching but can't find box designs for my old school kicker solobaric L7's S12L74 I have no problem with the construction once I have a design as I'm looking for direction here as this will be my first design box build. I have 3-12" kicker solobarics and am looking for a ported somewhat of a compact box design, something no longer than 42" long that will be going in an suv and playing mostly hip hop with some rock as well. I will be powering this with a crossfire 2000w amp at 2 ohms. Here is what I found for specs which don't specify port measurements to me.

Details:

titanium deposit cone

non-resonant aluminum basket

Santoprene rubber surround

dual 4-ohm voice coils for wiring flexibility (with a compatible amp)

frequency response 20-100 Hz

power range 75-750 watts RMS (375 watts per coil)

peak power handling 1,500 watts

sensitivity 86.6 dB SPL

top-mount depth 6-13/16"

sealed box volume 0.88-2.0 cubic feet

ported box volume 1.75-3.25 cubic feet

Recommended Q-Logic Box Type: none

depends on what kind of sound you want. Whats your musical preferences?

I would be playing some bass tracks for sure that I want to feel with some reasonable spl, but at the same time I don't want that annoying bass if that makes sense. Does kicker maybe recommend spec for tuning hz as I really don't know the difference between 32hz and 35hz but from reading I've done that hz is about what I want for soft rock and hip hop

Just shoot for 34 at 2.75 to 3 cubic feet. Moderate amounts of port area. Download xplicit audio app on your phone and there's a box calculator on it.

If I am looking for a box with 2.75 cubic ft, is the the "net" volume I am using in the xplicit app? and does this account for the sub displacement as well?

Are you using 1 or 3 subs, I'm confused. The 2.75 to 3cf recommended after sub and port displacement and is for 1 sub.

6 subs

It has wood, port and baffle thickness, sub and bracing displacement and ive been told its the closest to sketchup and autocad numbers.

thanks, and yes I will be using 3 subs and shooting for up to 9 cubic feet total

try to keep your port per foot around 12-16 for slot and 8-13 for aero. The more you overpower the more port area you'd want. typically L7s dont need much port area due to low displacement.
