will building a sealed enclosure behind the subs and jsut leaving them this way sense its all sealed from the cabin give any more output?

i think im just going to get a pair of FI IB 12s, sense these subs arent really made for IB setups, and they are decently loud, sound good and clear, and get really low i think a pair of the FI's would be better then putting these in a boz
