ok i have a box for my 2 pioneer impp subs... (the ones that have the blue dust cap and say 400 watt on the center in a black oval) i also have a volfenhag sub thats puttin 250 rms to each sub. i have my gains set and when u turn my volume up u cant even hear them! all u can hear is my 6x9's and the little bit of bass they put out. i was wondering if the box might be to big. its dual chamber 3/4 inch mdf and i think its about 1.0 cubes in each chamber. ne help would be appreceated
