Lvl4 In A Pure Brup Box?

[Team Sundown's Charles]

I was told that DC's aren't spl speaker but I'm thinking of using one or two in a spl setup in my car. I want to say in my class so I was thinking of using a sinlge 15" Lvl4 with Lvl5 coil. I can give it 2000 rms. or I could do 2 12" Lvl4 with Lvl5 coil but that means they will be getting 1000 rms. I need to be between 147 and 150 in my class to stay in the points hunt. The box would be a pure brup box. I was hoping some could make someone could help me out. This is my first year competeing. Would it be better to give 1 sub 2000 or 2 subs 1000 each? I know my car resonant frequency of my car is 56hz. I'm building a box now for my 15" L7 that is 2 cu ft tune to 54hz but it will be 2 weeks before i can get it metered. Do anyone have any subjections on a spl box for a Lvl 4 15?

I would double up on the subs for cone area, I think 2 subs with half the power would be louder than 1 sub with double the power, or at least in my testings thats how it has always turned out
