anybody know specs on how to build a box for a 12" eclipse sw9122 sub. i want ported with more spl than sq. it's going to be in a 95 accord so it cant be too big. i want to run it to a jl 1000/1 amp.
do a 3.30 cf box port tuned to 36 hz. That will include subwoofer displacement and port. there will be two pvc ports 4 in. inner diameter 11.56 inches deep each. youll have a nice bump in the 40 to 45 hz region (just drop the sub in and you should be right where i plotted you to be.)
