Any subs that work in small ported enclosures?

Prefer two 12's. I would like to go ported. I only have about 3.75 ft^3 internal (before displacement of ports and drivers) to play with. Is there anything that will work in say 1.25 ft^3 per driver ported to around 32Hz? Or am I SOL?

I have rl-P 12's. But I cannot design a box that will work since they really need 1.5 ft^3 each at 34Hz. After displacement, I am out of room.

This will be in the trunk of a grand prix with about 1600W to play with. Also I must be able to wire the subs to 1 ohm (so need DVC 4ohm).

This is for SQL as well.

Thanks all.

 
They'll be fine. Use aeroports and reverse mount them to eliminate driver displacement if you can.
If not, you'll still be fine.
Can't reverse mount as I won't be able to get the box in the trunk.

So if I went areoports, what size ports? 4"? 6"?

 
One 6" aero about 21" long should do the trick. That will actually be 3 cubes net tuned to 32hz.
So let me make sure I got this correct. rl-P 12's need a min of 20 in^2 per sub of port area. So 40 total.

a 6" areo-port is 28.28 in^2 of area. But the fact that it is flared means I can get by with less port area right?

If I went with 21" long. Do I need to port on the same surface as the subs and make a 90* turn? or could I go on a side wall and be able to go the whole length without the need for turns?
