I am lookin at about 3 cubes total in order to save room in my trunk for storage and weight reasons as well (sports car). THat is why I was still kind of lookin at the 10's ported. Power wise, I am open as can be. I have several amps that are almost brand new. I can throw anywhere from 1k watts to 3k watts at them. So, I am probably looking at 1k watts on each sub. Of course, I am gonna do power upgrades first and foremost.
