like against the wall of the trunk

i think you'd be best off making the mold first....like just the side and bottom. make it larger than you know you'll need. then make your ring for the sub. when you wrap it with the fleace, then you pour in the nuts and measure. then add or subtract volume by bringing the fleace in or out. you may have to wrap a few times or shorten of heighten you ring. at this point it's trial and error.
