NEED Help with Box design 2 12" FI BL's

[ficharger]

Hey guys thanks if your looking at this page and willing to help, I had a box designed previously for my last car on here but have recently changed vehicles and need a new design, all help is appreciated!

Vehicle : 03 Chevy Tahoe

Location in the vehicle: Behind second row seating

Space available (Length x Width x Height): 47" x 18" x 33" (18" is from the complete open available space in the front all the way to the back hatch, and i've read that if i do that then there wont be any space for air movement out of the port.... so the width might have to be smaller than 18"?)

Subwoofer make and model: FI Bl's

Subwoofer Size: 12"

Number of Subwoofers:2

Type of Port (Kerfed, Slot, Aero, etc.): Slot

What type of music do you like?: Rap, Hip hop, Decaf, generally anything similar to that...

Is your goal SPL or Everyday Music?: More everyday music, I go to a few competitions a year, but subs do have the "daily" option and not the "spl" option from FI

Tuning Freq (Hz): looking for 32hz

Questions: I would love for the design to have the Subs up with the port firing back, I want them to share the same chamber and have the port running down the middle between the two.

Thank you!!!!
