Enclosure ( I reccomend having a local shop build you one, but IF you want to save on $$ then a prefabbed sealed can do...)

*You are looking at about 1000 $ here shipped before install. Installation for this would run you around 250 to 350 $. Local rate here (at a good shop) would set you back 300CAD $.
all in all, about 1400 $ for a mid level system that will sound fantastic.
