I asked god, and he said that your trying to charge too much. That box is still a prefab box, and as we all know, prefab's are pieces of shit most the time. Im sure that box does great with your sub, but why would anyone who already owns a 12w7 wanna spend 400 just to enclose it when they could have a custom ported box built and shipped to them for far less. Many people on the forums will build you a better box, design wise, and build wise, for far less money. Unload your prefab JL box for like 150 dude. By that i mean, 150 or best offer. Oh yeah, god told me to say all that too. So dont argue with god.....or he'll send you to hell.
