Can somebody measure the little indent in the floor of the trunk for me? Also a picture from straight above would be great. I am looking for length width and height. When I get mine I may try to do a fiberglass sub box in it if it has enough volume.

 

I do not know the volume off the top of my head but it is not a perfect rectangle. The top is larger than the bottom. In other words the sides slope inward as you go down.

 

well if I can get the measurements from the smallest points that would work as well.
