when you buy it. it should come with a manuel that tells you everything about the sub and the box that you need to know

Right, the manual must carry all the specifications of the box you needed to house it. Double check yours. It should be there somwhere.

well, that information is NOT a requirement but many of the better sub companies do provide it.
