Anyone got any? I am at work and when I do a search all I get is a blank page. I was thinking maybe tuned to 33 or 34 and maybe around 4 cu ft. It will be going into a 2001 grand cherokee limited.

This is all that I see 4 @ 34 which doesnt help, and the links towards the bottom are blocked at work. anything else?

4 would be on the big side..

i went with 3.5 @ 32hz

I had a 3.5 for my 15 managed a 142 tuned to 37. I sold it to AQHDC3 while he gets his 4 18s together, might ask him when he'll be done with it.
(I specified 4cuft @ 35, but after construction and measuring the internal volume and checking the actual measurments against the tuning formula and other calculators it came out to be about 3.57 @ 37)

You can also try www.subwoofertools.net that's all I used for my design.
