cjvue Posted December 29, 2011 Report Share Posted December 29, 2011 a 4" should be sufficient imo.... port area is calculated pie*radius^2. Example: 3.14*2^2 = 12.56 My Build Log- T E A M S U N D O W N A U D I O - 2013 DbDrag WF SS1-2 - 5th Place 154.6db 2013 MECA Mod3 CA State Final Champ 153.4db Powered by: Sundown Audio Link to comment Share on other sites More sharing options...

RAM_Designs Posted December 30, 2011 Report Share Posted December 30, 2011 Yep, 4" will work fine...a 6" aero will require you to make it a custom length since the max length when they're stock is 17".

kr15 Posted December 31, 2011 Report Share Posted December 31, 2011 in my experience, trunks can get pretty loud and seem to play lower with aero to side...I ran an sa12 with 6in aero and by far best performance was sub back, aero to passenger side. Box was 3 cubes tho..lol Team Flex Issues Low tuning > God 2011 CALI AS1 STATE CHAMP Link to comment Share on other sites More sharing options...
