Need some help with port size!

[Flexxxin]

Hey guys this is my first post on smd forums! I'm building a ported box for two treo ssp 15's and need some help with determining port size. It's a wedge box for a regular cab 06 f150, 7.3 cubic feet after sub displacement, looking to tune at 33hz. Thanks

Torres calculator tells u what ur port area should be based on box size. 16 inches^2 per cubic foot is a good range.

check out the torres calculator you can tune it in there with your dimensions
