4 8" W7's

Does anyone know of a sub that would power 4 8" W7's and 1 12" W7 but wouldn't be too much power?

too much power is ok cuz you can adjust the gains accordingly. If you are contemplating the route of different size sub you will need to have different amps. if space isnt a consideration then I would contemplate 3 8's and a 13.5.
