[QUOTE="yamomluvsme, post: 8700486, member: 676077"] ports work nearly identical to subwoofers. the larger generally the better for output but they do have limitations. i like to do 14 to 24 per cube depending on tuning and power. for example if you have 4k and a 18 with a tuning of 35 id go with at least 100in regardless of box size. if you have 4k tuned to 40 85 can be used because you directly limit the displacement at higher tunings. too much port area is like having to low of a QTS. they start to peak hard near tuning and fall off fast after tuning. in most cases 12-16 works great but if you build a SPL car do big and work your way down [/QUOTE]
