I just finished the instal on my 12w6v2 and love it. It's run w/ a 600/1bd Fosgate amp and rattles the boat. I know it can't compare to some of the other systems on this board, but like you said the W7 needed too much power. As it is now, I have had to add a third optima blue top and my alternator is being rewound (from 50 amps to 125 amps)as we speak. Before the third battery and alt, the volt meter on the dash would bounce w/ every bass beat. I have no experience w/ the kicker stuff, although I here its good.
