also ... im going to use a sundown audio saz2000d for this sub. sub its dual 1 oHM how do i wire it ??

You got the wrong coil option to wire to one ohm so wire it to 2 ohms(coils in series).

Gross volume of your enclosure is 5.48ft^3 you need more port area though.

im using 3/4 mdf...5.48 seems like a lot... let me double check my measurments

ok , so i should have said that my box isnt square, its actually a pentagon. it took me a min to get the area

anyways, i got 733in^sq= 5.09ft^3

my port area can be H4.5x W12.5 X 22LONG ??? tuned to 33hz

Yes ?... no?

i just email fi an requested to change my sub from dual 1 to dual 2... hopefully its not to late
