Toxiccasper Posted July 12, 2008 Report Share Posted July 12, 2008 How many sq inches of port should I have for 2 12inch kicker cvrs? Quote Link to comment Share on other sites More sharing options...
Torres Posted July 13, 2008 Report Share Posted July 13, 2008 general rule of thumb is 12-16 inches of port per cubic foot. so depends on how big you're making the box Quote Link to comment Share on other sites More sharing options...
Toxiccasper Posted July 13, 2008 Author Report Share Posted July 13, 2008 So at 4 cubes about 52 sq feet? The design I have is 65 sq inches is that too much? Quote Link to comment Share on other sites More sharing options...

Kapetol T Posted July 14, 2008 Report Share Posted July 14, 2008 i have about 48 square inches and its really not enough, it have some massive port velocity. but i'm also too lazy to rebuild and its not very noticeable unless your head is right by the port. Not to thread-jack or anything but what happens then the port is too big and when it is too small. Quote Link to comment Share on other sites More sharing options...
