you can buy a plastic port, but they tend to create port whistle, its much better to jsut build one yourself, most likely if you call kicker and tell them what you are trying to do they will give you the specs you would need, build a slot port box, all my kicker subs are in slot port boxes, cant go wrong in my opinion. are you trying to jsut add a port to the box you already have? if so that most likely wont work, or at least wont work properly
