C'mon guys I need some input from those that know. I want it to sound good daily but have that "WOW" factor when I need to show it off. I'm going to have roughly 400-500Wrms per sub.

 

youll want ported if you want the wow honestly.

 

well in that car your seats fold down and in the dimensions u listed u will be able to fit 3 10's wide facing forward u can put subs at the top and ports below the subs or the opposite and it will work well I can tell u for a fact tho..dont exceed 14" or u will have a biatch of a time fitting that box into the area below the rear deck ... also most 6x9's dont even sound that good in the factory location because the airspace is soo damn small and if u use one with a large magnet structure it wont even physically fit in there.

 

33hz is mighty deep for 10's, but shorten or lengthen the port(s) an inch at a time to your tastes. Also, the port does not always need to be inside the cabinet. It can also stick out like a snorkle. Maybe you can point that port through an opening into the car.

 

i vote for Bandpass

 

flux capacitor is wayyyy better
