Design Questions for 15" Fi BL in 4 Cubic Ft @ 32 Hz Enclosure

Recommended Posts

Hey guys. i just purchased a 15" Fi.BL sub and before it gets to my house i was hoping to get a box design built. I am fully cabable of building anything i just need some help and advice designing it or possibly have someone design it for me. So heres what i got..


Vehicle : 2004 Chevy S10 ZR2 ext cab
Location in the vehicle: in the cab behind the two seats (sub up, port up)
Space available (Length x Width x Height): 45 x 18 x 28
Subwoofer make and model: Fi.BL D2
Subwoofer Size: 15"
Number of Subwoofers:1
Type of Port (Kerfed, Slot, Aero, etc.): slot
What type of music do you like?: mostly rap. i listen to a lot of decaf.
Is your goal SPL or Everyday Music?: my goal is to be loud but for everyday music. i would also like to hit the lows.
Tuning Freq (Hz): around 32 Hz
Volume : 3.5 - 4.0 cubes
Questions: should i go on the bigger side or the smaller side for the box? I keep on getting mixed info and doint know exactly what to do. Also does it matter if i go aero ported or slot ported? would it make a difference? also i am gonna be powering this with a Hifonics Brutus 1200.1 at 1 ohm. i am gonna end up getting a second battery and 1/0 gauge wire also. If anyone has any suggestions or is able to design me a box that would great! thanks guys. if you need any other info let me know.

Just did an enclosure for one in just about 4.5 cubes and turned out real good. . That was for a trunk though
