LoL id love to spend endless amounts of money but still gotta live an pay bills LOL ive never been one that runs top of the line audio always been the guy that does alot of cheaper stuff. So what if i ran 2 of the 15s in a ported box that would be just as loud as 4 15s sealed wouldnt it? Id do 4 of the 15s but dont think i have the space to run 4 ported.
