Greg, I think I did this one right....but it sure is pretty awesome to have input into anything I am doing on here. To say the least your input is right on and always appreciated, your first bit of advice to me a year ago when I first bought my Blazer was to "drive it for a while before you do anything to it, just enjoy it".....best advice yet!!!

I am going on a year now and just got it figured out, sure am glad that I did not get into something over my head or just do things to it that look cool that I personally do not need.
When I started these I did a ton of research online about fiberglassing, once I figured it was something I could tackle it was on like Donkey Kong.
First I used the old stock panels and traced the shape onto a piece of 1/2" MDF. So the new panels that I built do have a solid back to them, each sub is very contained as far as any air displacement.
I then cut out the "donuts"... you know....the rings that the speakers screw into out of 1/2" MDF as well. Next I built a "tripod" to hold the donut at the height and angle that I wanted them to be on the side panel, I used pieces of wood cut to different angles for this. So it was basically a skeleton of what I wanted.
I then stretched some fabric over the whole thing and glued it down, this gave me the basic shape that the panel would look like when I was done with it. Next I mixed up several batches of the resin/hardener mix and basically painted the whole thing with that stuff. Once that dried it was harder than hell and gave me a base to start the actual fiberglassing. I put about 3 layers total of the fiberglass mesh down, I would sand/grind in between coats.
Once I figured it was a solid enough surface I started applying Bondo to it to get it to a finished look that would look good in my baby. I was worried about the air blowing out of the subs also, so to seal it a little better I reached inside the areas for the subs and sprayed some expanding foam where the fiberglass meets the MDF. I put a couple of wood rails behind it so that I can anchor it thru the speaker holes in the front and rear so there are no screws or bolts visible from the outside.
I had them on for about 4 months before we moved to Kentucky and they sound pretty awesome, all I have been doing for the last couple of weeks is dressing them up and getting them to the quality look that I wanted. so in the end I am pretty pleased with them.
As you all can see I am not to good on doing any type of write up so if anyone wants I can shoot you some better pictures of them or try to explain it a little better, I wont be putting them back on the blazer for a few months as I have a guy lined up to paint it for me so I am in the process of stripping it down and getting it ready for that. I will get some better pictures once I get them put back on.
