im building a box 4 a 12" icon under the back seat of my truck. i can get a box thats 2.0 ft after displacement 4 the sub. ive done a few boxes with slot ports but never aero ports so im not exactly sure where 2 go from here. i want 2 do external aero ports so i can tune this box 2 33hz... now my dumb question is:
i used this calculator:
http://www.psp-inc.com/psp-inc.com/cgi-bin/port_length_calculator.cgi
it says if i use 2 3" aero ports the length needs to be 15.3 inches.. is that each or a combined length?
