Platinum Member Username: Nyyfan13Http://lowdo... Join My User... Post Number: 10872 Registered: Jul-06 | I wouldn't force it. You have about 12cuft net. A single twelve would (typically) need just about 2-2.5cuft after sub and port displacement. If you are set on 12's I would do 4 twelves and call it a day or if you want to step up a level, you could do 2 15's. Just because you have the space doesn't mean you have to use it. 4 12"s in a correctly sized box > 6 12"s in a small box |
