I want to port 2 Alpine 10" Type S subs. I am powering them with 300W Rockford Fosgate amp. I am thinking I want to put the subs in two different compartments and each one has their own port. I like boomy so I think I would want a fairly large box. Could someone recommend something to me? Alpine just shows what they recoomend for a sealed application. Maybe sealed it the way to go with these subs
