zfrerichs Posted March 8, 2009 Report Share Posted March 8, 2009 fi says 12-16 sq inchs of port for every cube in the box but you can get away with a little smaller Quote Roseville, CA Link to comment Share on other sites More sharing options...
bkolfo4 Posted March 9, 2009 Report Share Posted March 9, 2009 100-125 sqin of port. I run a 40.1 @ 0.5 ohms on each of my 15's with no problem, but I would say 2-3k each is more than enough.
