I was just wondering...
 

What kinda setup would be best for me cause I listen to a lot of trance and some metal. I was thinking 2 10" subs would be best, but what about the box, sealed or ported?

Sealed or ported? I think that depends on the subs. Some behave better ported - some sealed. Look at the specs. And bottom line - personal taste. Ported set-up is usually louder.
