ive been considering getting 4 15" re se subs, i would push them with around 1000w rms each, but my dilema is the space in my car, the biggest box i could get in the hatch would be 10 cubic feet before port or sub displacement, my question is would it be better to just leave it sealed or port it and loose alot of volume??? and would that be louder then my current setup of two orion hcca 12"s
