Supspt454

Juat wondering about people's real world experience on the SA-8? Is this a good combo SPL/SQ sub? I like the large output from a small driver. Power will come from an old school Rockford Fosgate Power 300 MOSFET bridged. Any thoughts in boxes? I like the idea of placing the subs on each side of the trunk toward the rear in the side pockets. Ported, or sealed? Thanks in advance. I'm a new b by the way:) Shawn
