Gold Member Username: CenusHicksville, Ohio Post Number: 2736 Registered: Jan-05 | its gonna be common chamber, i'd like to use 2 6inch ports cause it would fit perfectly, have 2 subs firing back the 3rd firing up in the middle and a 6inch port on each side of the sub, then i'd just make the ports an L shape. |
