wall mounted amp enclosure

hello, first post.  i'm attempting to build a wall mounted amp enclosure that will be on the back wall of my Element.  thus far i've taken a fiberglass mold of the area i want to mount it to, and a little extra so i can cut to size.  did 1 layer of mat plus 1 layer of cloth once outside the car for reinforcement, but will probably need a few add'l layers of glass for strength.  current plan is a few more layers of glass, than hot glue a platform onto the glass, wrap the wood shelf/fiberglass mold of wall in cloth and add resin to that to make a decent structure to mount the amp on, than eventually make a glass enclosure/top to hide the amp.

a few questions for the experts as this is my first foray into glassing.  how many layers of glass should be enough to support  a vertically mounted piece of 1/2" MDF and amp?  my thinking was the glass is mainly for form, than the MDF for strength, but the glass will have to have a certain amount of strength to support the MDF and eventually the amp.  for mounting, current mounting thought is use a few existing screw holes to mount vertically, than also stabilize the base and have the weight of the base in the 'pocket'  to keep from much movement.  does all this sound doable or ridiculous?  any input welcome.

image to help visualize this.  thanks in advance.

crap, pic worked in preview mode....maybe this link will work

actually, was already able to remove it from the pocket as i didn't glass it all the way in - just enough to get the rough shape.  don't get me wrong, still a pain the arse to get out, but it's out now.  5 layers, cool, will post pics of the progress. 

for wall mounting i've got a few spots that i can remove the OEM screws and use a longer screw to mount.  should i also use industrial strength velcro tape for the rest of the mounting?  the pocket form is there to help support some, by running MDF into it, but anymore suggestions?

Depending on how tight that FG was applied that is entirely removeable :P Even deep it prolly still could have been brought out(As long as you don't go past like 6 in). Mainly depends on how tight the FG is to the top portion of the wall. If it is tight it'd be incredibly hard to sufficiently bend for the pop out. If it isn't so tight, it should slide up and out well enough... Though I could see the initial concern.

First project and not bad at all... I'm guessing considerable reading? My first project sucked. :)
