port tuning

[speedball1978]

ok i already built 2 boxes one for each 12, i got 4 in flared ports coming in, the box dims are (outside dims) 32.5 x 13 x 13 the inside is 31 x 11.5 x 11.5, before i get my ports in tomorrow and the new cap i would like some suggestions on what freq i should tune the boxes to... the subs are kicker cvx 12 inch, currently am using 2 separate proboxes, which is insanely loud for a no wall (thanks to the head unit). but the boxes are small which is why i built the new ones a little bigger i plan on getting it some resin on the inside to stiffen it up. The reason i have 2 boxes built is because of the way the trunk was made damn chevy, lol, jk.. it only allows me a certain size to fit in, i plan on doing a wall within the next 4 to 6 months due to the design of the trunk and the gap i have behind the back seat there's a foam pad that covers it up which is like 6 inches thick in a triangle i'll have to post pics on this one in the next few days so you could see what i'm talking about..i already understand the lower the frequency i tune it the lower notes i'm going to hit, but its all spl, i haven't competed yet but i'm thinking about my first comp this weekend. Any suggestion or opinions would be great. The trunk is already dynomatted around 80 percent

35hz. And don't bother with the resin for a box like that.
