Dude...I'm searching!
Hey guys I know these sort of threads are frowned upon and I have been searching around here trying to figure this out on my own but I need some help. I have a 08 GMC 2500hd crew cab, I just bought a box that has been custom made to fit under the seat and I am trying to match up some 12's for the box.

External Dimensions ( not including humps for magnets or legs) are 50.5 x 15.75 x 6.5 x 3.25
Humps are 1.75 x 8.25 x 9.5
There is a port that is 2 x 6.25 x 13.5 that is dead center
5/8 = .625 box material
6.5" MAX mount depth
Amp for both is a Alpine PDX1000 so about 500rms each.
Budget - I would like to stay around $400 for both or under BUT I would be willing to spend more if I have to.
I am not to sure how to find out what the box is tuned to or if I should calculate in the port with box volume or not?
I appreciate the help in advance.
