inverted? people usually do that when they are limited to space and they cannot do ported...or they just wanna look cool. i wouldnt recommed inverting your subsI don't know what my box design will be yet but I have a good shop with table/radial saws/jointer/router etc. I was thinking all MDF, braced, slot ported front facing and I will have the pass rear seat folded down most of the time and the ski port open. Might mount them magnet out too because it looks cool.
