#1 it's a BAND pass box ...
#2 What are the new subs RATED at

That would determine what amp to run...
#3 Direction it depends on what frequency the box is set for and what type of music you listen too... Try it one way ,then turn it around to see what sounds best to you
# 1 yea w/ the plexy glass and recessed sub and the ports and stuff
# 2 subs are rated at 1200 watts
# 3 well i listen to a lot of rock like three days grace
