I am thinking about attempting to mount a set of 8" mids under the center dash location of my truck. When I see it in my head, I picture something like a large cup holder cut in half down the center, but I am totally lost on how I might lay this up to be fiberglassed. When I attempt to draw a top view, it looks like cleavage, with the boobs being the cones and dust cap(no pun intended)! Can anyone picture what I'm trying to describe, and how would you begin to lay it up for glassing?
