Ok sorry for the ignorence. Say im running 2 12's on 1250 rms a sub there from AA in a dodge crew cab? If that helps. So from what i can see a fourth order box, the subs are inside the box and the mag sits inside a sealed box and the cone is in a box with a port? Would it make my system louder, deeper, ect in a box like that or should i just make a standard ported box to spec. I want it tuned to about 30hz.
