I dont know how to do the whole slot plot thing,but I want to build a box for lets say 4 12" kicker cvr,Now kicker tells u what size the port needs to be for a single sub,If I have all 4 kickers in a non chambered Do I build the same size port,if not can anyone give a website or something where I can learn how do the slot port magic.Thanks for any help.

Software will help, but you could do what you said and just multiply by four. I always try to have no less 12-14 inches or port area per sub. For a round port this would be a 4 inch pvc pipe which works with very little port noise on my Brahma 12 which has way more excursion that a Kicker CVR. I would say about 60 inches of port area would work very well for 4 Kicker Cvr's, 15 inches by 4.
