Welcome to the forum, first give us some more information to help us help you. What car will it go in, what space do you have available, what other equipment will be used and do you have any upgrades to your electrical.

I would stick to what FI recommends for their sub and no matter which size you pick within their specs should do you justice.

depends on how you like your bass and what music you listen to, I would tune between 30-33Hz

looked some stuff on tunning and i came up with this box im not sure if its right i used online calculators here it is out side dia. 16.5 h 31 w 21 d the port is 15 h 2.5 w 16d 4.1 cu.ft with out the port and driver it should be around 33 that what im looking to get

[jcarter1885 995]

that box is 4.19ft^3 @ 29.05 Hz

here is a better box for ya:

16.5"H x 31"W x 21"D (Outside)

15"H x 3.5"W x 20.5"L (Port) = 52.50 in^2 (Port Area Range:46-61in^2)

3.82 ft^3 @ 32.98Hz after port and sub displacement since you want it at 33 Hz
