bkolfo4 Posted July 1, 2013 Report Share Posted July 1, 2013 If you only have one port in the middle, then use the total box volume and the port length will be the length of the one port in the middle. . . Current system: 1997 Blazer - (4) Customer Fi NEO subs with (8) American Bass Elite 2800.1s Previous systems: 2000 Suburban - (4) BTL 15's and (4) IA 40.1's = 157.7 dB at 37 Hz. 1992 Astro Van - (6) BTL 15's and (6) IA 40.1's = 159.7 dB at 43 Hz.
