I searched around but haven't been able to find anything about this. I would like to mount my convenience spare tire under the rear of my car... The reason being is to clear some space in the spare tire well for a single shallow mount subwoofer. Has anyone done this before, and does anyone see any problem with doing it? I feel like it is light enough where if I were to just drill holes inside the current storage area, put bolts (lugs?) through and use rubber washers on the outside (to keep water out), I could simply bolt it up.
