What do you guys think about them? Pro's, con's? I'm thinking when I bag my truck I could do a blow through and just put the tank and compressors in the back of the bed and sheetmetal over all of it, so I can still have the rear seats to use, a guy is offering me 2 12"s in a box for $200, so....actually if anyone wants them, I can buy them and hook you up...
