Car audio system questions?

OK, so I have a 2003 Lancer OZ and I am trying to get a decent sound system for a decent deal. I am already getting an MRP-M500 amplifier and 2 Type R 10" Sub-woofers. I have an Alpine head Unit ( I think its a CDE-123 ) anyways what else do I absolutely need to get to make my sound system work for example, Vented boxes or sealed boxes, 4 gauge wiring or 8 gauge ect. I am a pretty big noob when it comes to sound systems and I am not afraid to admit it... that's why I am here. thanks
