will pay a few bucks if it means that much to you

i built this box to go in my 96 impala. going in it is a dc audio lvl 4 15. i need help adding two tube ports.

this box, according to my calculations, is 4.465 cubic feet after sub displacement. i want to add two tube ports on either side of the sub to help with visual appearance since i love symmetry.

what tube port diameter and length do i need for a 33hz "sq" tuning?

i'd be happy to help. are these outside or inside dimensions?

a pair of 4" ports @ 12.5" should get you there. That may not be enough port area and going larger will get into some very impractical lengths.

It all depends on my setup. I'm using 4 4" aero ports on my build. 2 4" pipes should be fine for you cut to the specs on the site
