    Got 2 Fosgate Power HX2 12's need to build box

    I have a pair of Rockford Power HX2 12's and I want to build a ported box for them. Anyone with any experience with this sub, as far what tunning frequency, box size and such would be great. I want it to be as much SQL as I can get from these subs. I think I am going to go with a slot port. Any info and suggestions would be great. Thanks.

    I have a Mmats d100hc, so I'm guessing around 800-1000 watts each

    As far as space I am pretty good, plenty of room, I just need to know cubic feet I can make it work

    what kind of car/truck are they going in? That could change the firing positions of the subs/port and thus change possibilities of the enclosure itself.

    Oh, well you can have these in a huge ported enclosure and still have room for a few dead bodies back there.

    IIRC the manufacturer recomends 2.25 at 38hz for each of those.

    38Hz seems a little high
