I recently pulled out my subwoofer to provide access for a paintless dent repair technician to fix a dent I got a while back but never got to. I know a lot of people prefer more bass than the premium sub delivers but for me it is pretty good sounding and not in desparate need of mo-bass. What I did notice about the factory enclosure was just how light it is. Since I have it out, I decided to slap some Noico 80 mil sound deadening material. I don't expect miracles here but hopefully there is a subtle improvement of deadening such a flimsy enclosure. Will report back after re-installation.
