Need help with 15" L7 ported box

[blabo219 10+ year member]

I have one 15" L7 kicker and a zx1000.1 powering it..

at the moment i have a temporary ported box my friend built but i need to make my own because all of the premade boxes online are way to small for one sub.

I am putting it in a 1998 olsmobile cutlass and the trunk space i have to work with is either (pushed back all the way to the seats):H-16.5 W-35 L-20 or (pushed up to the back of the car):H-20 W-37 L-20

I am looking for a box between 3-5 cu. ft.

Also if anyone has any suggestions, what should I tune the port to? 32hz?

O yea, you got the right idea. Id go pushed against the seats and sub and port firing rearward.

Type in your H W & D, then 4 for port width and 8 for port length 2. Ya get 32 Hz. 4.328 cubes before sub. Should hit real low. If ya got space, Id double up the face of the box too, keep it from flexin.

35 hz would be better....

I agree alotta subs sound good with a lower tuning but imo 35-40 sound the best with solo barics. I listen to alotta rock so im always favored to high tuning.
