hey i'm looking to buy a ported box for my 12 inch idMAX. where should i get it? i checked out powered4sound and a snail shell for a 12 inch is 250 bucks. is that like way overpriced?? i thought i could spend maybe 100-150 to get a good box.. i sure as hell don't wanna buy a crappy *** box that i couldve probably built beter than myself although i have no experience.. if someone tells me powered4sounds boxes blow the others out the water then maybe i'll go with them.. but are their any other reputable places that build boxes??? and how are their reviews??
