Rockford HX2's better in a sealed or ported box?
I am into buying a new sub box that will have my subs facing towards the front of the car. My subs are 2 12 inch Rockford HX2's. I told the guy that would maybe be building the box if I decide to buy a new one is I would want the box ported. He said that Rockford's dont really need ported boxes. My sealed box right now is good but I want my subs to hit harder so people outside my car can hear them. I know that ported boxes hit harder for rap music. So is it better for HX2's to be in a sealed box or ported box?
