I was asked to kerf this enclosure to match the contour of the rear seat. Kerfing in a sloped wedge is very tricky it adds a compound angle to the the sloped walled that is also curved. The box is made for a sa-8 with a mounting depth of 4.75" Most of these builds have a bulge in the top to account for the mounting depth I was able to flute the roof so it it gradually gets deeper. This means the enclosures roof is only 1/16th" at the edge of the pocket the wedged flute minimizes flexing. To cover the exposed seams and kerf at the top I planed down 3/4" mdf to 1/16th and added the skin to keep the lines clean. The double walls were needed to displace more volume, hold up the recessed top and give an extra L shaped glue joint for more surface area for a better seal.
