OK thanks the speakers are http://www.edesignaudio.com/edv2/pro...products_id=33
I currently have them sitting in the stock 6x9 mount but they will actually hit the deck at different frequencies so I had to cut power to them and keep the volume low
I'm not sure I understand what you want to do with the speakers and the above/below thing.
I should have clarified a little better I will be using louon(sp) board to seal the empty space that will be on both sides of the speakers. I will cut a hole to match the mounting location and then eather place the board on top of the deck or below with bolts holding it in place and liquid sound deadening between the surfaces. The speakers will be dropped in from the top and bolted to the deck/wood or wood/deck.
