i am just tring to get some air space figures.
Alpine tech told me to just put them in a .6 cubic foot sealed box each. or 1.7 cubic foot ported box with 23" port and a 3 x 11 square port
the seal box seams right but the ported box is just crazy in size.
any suggestions?
For past box building i would try a .5 cubic foot per sub sealed chamber - 4 x .5=2. plus woofer displacement
the ported chamber .75 x 4 = 3 plus port dispacement - probably a 6 x 15 - 12" long
i will dive each woofer with a alpine MRD-M1005 each - connect with the amplifier link...
