150 is very possible. just takes alot of trial and error. i'd like to say i have done it with under $600(old HU, SX18, $150 dx700, welding cable, and some other misc.), but the truth of it is my wood and building materials have far exceeded that number. countless rebuilds and jumbo man hours. good luck to ya...all of the equipment you listed is very capable of 150+ db.
if were to choose off your list, it would be a pair of tempests
PS - tommy, my amp is only rated at 380w //content.invisioncic.com/y282845/emoticons/wacky.gif.cf4a48f9e6dfe9504ffd2c946fd2f340.gif
