Currently have the stock kenwood's and very unhappy. I've been doing a lot of reading about the systems people have built. I'm looking closely at the wet sounds 3-some or double up as well as a the Exile XM7. I'm wondering what kind of power I'd need to put to these towers. I've already got 3 pairs of Polk db651s ready to go. I'm also looking for some recommendations for a sub. Will of course be doing a dual battery system and probably a ws420 EQ. Thanks for the input.
