I did manage to get some work done even though it was very hot

Started with breaking out the trusty old router and churn out a 3 layered MDF baffle:







The baffle was then centered in the box itself (you can see I had to chamfer the inner MDF ring somewhat to fit within the frame):



Cloth was then stretched over the baffle and frame and resin applied:





Followed by two layers of mat on the outside which will be followed by several layers from the inside for rigidity:



When the polyester had hardened - which went quicker than expected today even though i cut back on the catalyst - everything was sanded down a bit and test fitted in the trunk:







IMO it fits quite nicely and follows the contours of the adjacent trunk panels. I will be adjusting the back part of and trace the contour a bit more in detail with some rage gold to ensure a flawless fit.

I think this sub box is coming together quite nicely :blush:
