    Question about a fiberglass set up

    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?

    Sorry, I'm trying to think of other ways to explain it... Say you take one of those sonic tubes they use for concrete deck footings, you stood it on a table, and cut it from top right to bottom left. You would be left with 2 equal, 3 dimensional triangular cone shapes.

    If those were 8" tubes, and you placed a woofer at the bottom and placed them on the transmission hump under the dash of a truck, and aimed them at their respective headrests.

    If the gauges were at the back, like looking down a tunnel. Now cut away the outside half of each tube...lmao

    Re: Question about a fiberglass set up

    I'm not understanding what I'm seeing. How does the cone interact with the diagonally-cut tube? Is the black-marked spot supposed to be removed?

    Re: Question about a fiberglass set up

    Are you wanting to make a waveguide for each speaker? Or just for looks? What information do you intend for these speakers to play? Dedicated center channel? Midbass? Subwoofer?

    Winner, winner, chicken dinner!!! Now, if I put two of those back to back and aimed them each their respective headrests from the floor in the center under the dash, like reversed kick panels. They would be for midbass/midrange. I can not believe you figured out what I was trying to describe! Could I lay that shape up with a cardboard tube, and fiberglass that as a mold?

    Or, what about crossing the tubes in an X pattern? I think that would look really tricked out, but would it mess with the sound?
