depending on tuning, I'd shoot for 42+

if its a daily driver id just go with 30 sq in, its plenty. if you want to do SPL, make it big //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif bigger port doesnt always mean louder though.

I came up with a plan for 3 cubes, tuned to 32 hz, with a 40 sq. in. of port. I think that'll do.

In 2 cubes I have 30. Shoot for 35-45 and you will be happy.
