To get the sound out from under the coal load I drilled some random holes through the fiberglass and coal. As for the drill bit size I just picked on that looked good. 
More holes may be needed but until I order a micro Tsunami sound decoder and get to hear how things sound the ones I drilled will do for now.
A few shots of the finished coal load in the tender covering up the speaker box.
When it is in place in the coal bunker the holes I drilled cannot even be seen. I am happy with it and the idea of the fiberglass coal pile shape will be used again when I add sound to my 4-8-2 vanderbilt tender.
More photos on the ten wheeler build as soon as my camera battery finishes charging.
