Help With Box for 15"

[shockaa 0]

hey i wanna enter iasca rookie competition but the sub im using is a 15" atomic apspl15, in the category im only allowed 1 4" aero port, what size box should i use and what length port, the car is a mazda protege5, right hand drive cause im from trinidad, the amount of power is 1500 watts, the box will have to make high spl while playing music since in this category you are only allowed to test with music

is this box for daily listening or just for burbs?

its cant be for burps cause in rookie you are required to play audio when testing spl,

ahh I'm not some spl pro but in my opinion you'd do good by going for a huge box and the tune to be in the low 40's. It would peak at the mid to upper 40's and that would be louder since it is probably closer to the resonant frequency of your vehicle. Give me some dimensions to look at and I could mock you up a box using a program. Does that car have a trunk, or is this a hatch setup?
