this weekend I plan on building a new box for my sp4...I was thinking about 7 cubes net at 30hz...but I cant decide if I wanna go with a simple slot port or try some aeros..what would be my best bet using aeros, 3 6" flared aeros, or 2 8" sonotube aeros, or a "10 sonotube aero

btw this will be going in my Jeep patriot sub up, port up...running on a saz3000 at 1.4 ohms (each coil reads .7)
