I have built my box for my 4 12" L5's,The total box is 10.27608- sub displace ment which I think is .078 cuft per sub so 9.96408,And I would like to have 4 4" ports,but I dont know how to do the whole tuning thing ,Is there a website calculator I can use for this?If not can anyone help me with port length plans?Oh yea also I will add piece of 5/8 mdf to the front for extra supprt.The rest of the box is built with 3/4, And I am not sure what to tune too,this will be a daily setup and I would like to tune it pretty low, anywheres from 32-35 I guess.Open for tuning suggestions.Thanks for any help or input!

I know that but I got off early today and was bored so I just built it ,Think I might have to just have someone on here to do a whole box plan for me

yea bro, you will definately need a box plan. Don't rush into things, but to make smart decisions and plan ahead. You want your enclosure to be close to perfect.
