Enclosure Design Help

I thought I posted this, but then again maybe I hit preview..

I need help designing a box for my car.

Currently I have a small sealed box, and when fooling around, have peaked at 141 @ 35hz. 25 or 45 hz were not as loud.

The new box will be built in the back seat.

I have four JBL P1022s

and one Fusion NV2500 running at one ohm.

I am looking for somebody to design a box, and provide cut sheets.

I am thinking the best way for me install this, is as four separate boxes, since I doubt I can build it in the car properly by myself.

I am thinking of having it tuned around 29hz.

What would be best? T-line, or Just ported? I know the specs for my subs aren't the greatest for a T-Line... but I would like to try it... I want it to be as loud as possible, but still be good for music.

I know Im not gonna reach the stars with what I have, I know its not the greatest, but I'd like to do as much as possible with what I have.

This is going in a 1990 Taurus Sedan.

So, who can help, and how much?

email is probably best since my internet is sketchy,

zeptoplix@hotmail.com

Thanks,

Ben

5 cubes tuned to 29hz, How big is your trunk? You need to provide measurments. I would do rear firing subs and port.
