i have never heard a sealed box,what about sealed size but with areo port/ports

if you could fit 34 x 14 x 17.5 then you could do a external (outside the box) 6" aero port 15.5" long. this will put you around 3.5 cubes net tuned to 33hz

edit: 3/4" wood

Do the areo port box, seal the trunk off, and do the external aero port, porting through rear deck.

i did think about the areo port through the rear deck because i have a big hole there where my oem 10" sub was.

I wish i had fold down seats, This is may daily driver.

if you don't care for your trunk much just run a 4th order. This requires lots of planning however

i have a caddy cts ,trunk is on the small size

Right now i have 1 12" incriminator audio LI series. May want to up grade in the future to two of those subs.

This is the max size i can go 34"wide 14"height 16" deep

this are the recommended specs for a ported box.

1.75-2.5 cuft port Area 29-40inches tuned to 28-35 Hz

My crrent box is tuned to about 32Hz

Can a Box be made for 2 12's with that size limit

I think everyone miss read your dimensions/ with those given only give you 3.4 cu. Then when you take out displacement , port area. It doesnt look like two 12''s are gonna work for you.
