ok i need some advice on building a box for my subs. they are 15's min = 1.25 cu. ft. max = 3.25 cu. ft. they are 650 rms each what would be the best volume size to have within the max and min? thanks. i have a problem as i havent got room in the boot to have two ported subs as they require 4cu.ft. each! so im going for the sealed. thats why i want to know the best vol for the subs.
would 1.673cu. ft. be any good just for low end or what would be the best for low end, as that is the main role they will play. i can only fit the two of them in if i have both boxs at 1.673cu. ft. but if it is better to just have 1 sub and bigger box size?
