Any one have any Idea what these things like for an spl App. The subs will be seeing about 3000 watts each and they are going in a 1997 explorer any ideas would be a great help. So far I have been using memphis mojo's subs up ports back 3 4 inch ports about 4 cuf. and my loudest score is about a 151.5 at the head with the mojos.Thanks Bud
