    Re: Four 12" subwoofers...

    did you look through the plans already posted?
    i don't know if there's any for 4 subs but 2 double sub boxes can be reconfigured to be one quad box



    Car : 1988 Pontiac LeMans Aero-Coupe
    aka 'The Death Rocket'
    HU : DEH-16
    Fronts : Infinity tweets
    Rears : XS-R6941
    Subs : (2) XS-L100P5W
    Sub Amp : Memphis 16-PR 150.2
    Enclosure : Sub Zone sealed (2 cu. ft.)
    Hitting 130 dB* with this setup.....Priceless

    *130 dB rating is not guaranteed. Reading was done with a Scosche Boom Stick and therefore can not be relied upon.
    Everything stated by me is my OPINION....if you don't like it I don't care......

    Re: Four 12" subwoofers...

    Alright. I think the outer dimensions of the box should 36"x36"x18". Make separate chambers for each subwoofer. Assuming that you will be using 3/4" MDF, the internal dimensions of each chamber should be 16.875"x16.875"x16.5". This will make each chamber 2.72 cu.ft.

    Personally, I think you should use tube ports. PVC pipe works great. If you were to use 3.5" PVC for the ports, you'd need to make each port:
    8" to be tuned at 30Hz
    7.4" to be tuned at 31Hz
    6.75" to be tuned at 32Hz
    6.2" to be tuned at 33Hz
    5.7" to be tuned at 34Hz
    5.2" to be tuned at 35Hz
    Well you get the idea...
    If you want it to be tuned higher then that let me know. I'll get you the figures.
    Hope this helps...

    Is there a particular reason why you want to use a slot port? There's barely any difference IMO.

    If you don't have many tools then I think the tube ports would be easier.
