well i can give it max 24^2 in., it is an open cab, and its only 350 watts...so whaddaya think...also JMAC i have a question about my box design...not a design just a question about the box volume above the port and whether the sub would see the airspace as net volume or as part of the port...

Absolute bare minimum = 14 square inches ...
If it's in an open cabin with 700 or more RMS on tap, I wouldn't go with less than 25 square inches ...

why i was asking what kind of box. supppose i should've said install... my bad //content.invisioncic.com/y282845/emoticons/chix.gif.b7a2c3844cd4b49b8430443da768250e.gif

not to thread jack or anything, but is there a general rule to go by when calculating port area? Like, because im planning on 2 Death Penalty 15s for my next install and dont know how much port area im going to need for that. And instead of everyone keep asking similar questions, they would know what kind of formula to use (if there is one)

Oh while im at it..... figure out how much port area imma need. two 15s, 900+watts of power going to each....fired into the cab being sealed off from the trunk....and getting 3.5-4 cubes for each sub (if any of that information is needed)
