Don't take it personally Rhett, but I'm not really prepared to give =
you
fiberglassing advice if you aren't willing to gain a bit of knowledge =
about
stereos in general before you start.

I am not really looking for stereo advice, more for the suggestions on
glassing. I have glassed flat things before. I'm just looking for any =
easier
molding ideas or connections for supplies.
Thanks for the suggestions though,
Rhett
