Ok the box im looking to build is for 4 12" kicker cvr's i figured out that if i use 3/4 inch mdf and build the box 15"high x 30"wide x 33"deep i will get 7 cubes.
now im looking to put the subs on the top of the box as this is going in a cavalier and im stuck on what to make the port size/depth any help would be greatly appreciated also stuck on what frequency to make it this box isnt going to be for competions im just looking to build it for my daily driver thanks...so i will be listening to all different types of music..

How about starting a little higher then 35 try around 38 or 37, then if it doesn't work to well work your way down..

i would say tune it low likw 32-35hx, so you know your subs wont over exert(spelling) themselves i you try and listen do something reallly deep.... when you calc. you port size/length dont forget to use the ft^3 you have after you take away the sub displacment AND the port displacment... here is a good online calc for ports..
