I'm thinking about sound deadening and sealing the back doors of my '05 Escape and installing small subwoofers like these: Elemental Designs e3.6 subwoofers. Cutout diameter is 5.7" and mounting depth is 3.518", the latter being the dimension that has me most concerned. Would I be able to fit these? Would I be able to fit 1/2" or 3/4" thick adapters/rings in there without having to cut apart the factory door panel? I would go the traditional route with subwoofer box in trunk area but I dont want to give up any cargo space. I am going to be running Morel Tempo 6C coaxials in sealed/deadened front doors off an amp. I really want to make this work
