LOL. This is definitely the right road to go down but definitely not a guaranteed 150. 150 is "easy" for those that have already achieved it. For those of us that haven't, it's not the easiest. I am running twice the power you are (DDz2), and have 2 DD 9515g's in a 8 cubic foot box tuned to 40hz and I'm doing 149's. Granted, it's a music box and that's why it's 8 cubes and that's why I am not at 150, but it's just not as easy as everyone makes it out to be. The only thing I can actually brag about is the deals on got on this expensive equipment and the fact that I don't drop below 145 throughout the sub-bass spectrum. (well I've never metered from 20hz-29hz)
