[QUOTE="Edzzed, post: 8040704, member: 651289"] You still building boxes. I need one. I considered a generic one but my subs list the specs and none of the generic ones have tuning listed. The 2 subs I have are image dynamics. It even lists the sub displacement at .07 cu ft. Can you build a box to go in the back of an 98 gmc extended cab. It would be nice to have down firing. I'll have to measure some dimensions if you can build it. I would have posted the link but being my first post it was DENIED. lol Ed ENCLOSURE SPECIFICATIONS TYPE OF LISTENER LARGE NORMAL SMALL SEALED VOLUMES GROSS 1.5 cuft.
