Clarion Xw Series 15'' Specs, Enclosure Size?

[F N LO]

hey guys, i have a customer that has 2 15 XW series clarion subs, he wants a bx to go in the back of his pickup, he has a blow through, so i am build the front with a lipe so that it will be air tight with the fron of the bed, in turn forceing the air into the cab...

i would like specs or info, i have searched and google these subs with no luck,

if anyone has any recomendations on ports(tube, slot) and how much area should be good for two of these things, thanx for your hepl guys,

Travis,

also he is running a new clarion dpx1500 @1ohm, so the subs are seeing about 750 rms each...
