Beginning subwoofer box construction. we are making the enclosure to fit in the same place as the foam insert next to the spare tire. we'll get the recommended 0.6 gross cu. ft. with using 3/4" MDF. we'll be using US Composites B-440 resin and 3/4oz chopped mat to reinforce each seam and joint. we may glass the bottom to save 3/4" in height.
there are 13 sides. i pre-cut out strips of MDF that were the height we needed. then i used my table saw to cut the necessary angles, working my around the enclosure (so each saw angle was used twice).
with the Hertz ML2500 trim ring in place
the sides needed to be glued in sections, then we'll glue the sections together. i numbered each piece so i could remember orientation and order.
