How to Make a Fiberglass Enclosure

For the sides of the box you built where you have it kind of curved with piece by piece did you just glue them together or would they have to be sealed with some form of silicone for it to be air tight?

Hi, is there any chance you could go in to some more detail about the cover? The article just kind of skims over that and it is something I would really like to do.

Yes, as long as you can make the enclosure walls thick enough so that it will not flex under pressure.Jeff

I glued the cuved peices down first and then I fiberglassed them together and sealed them to the base. This made the walls stronger and also air tight.Jeff

Well you got the foil down and I am a little unclear after that. Perhaps I did not read it well enough. Did you just layer strips directly on top of the foil? I would like to mount my amp like yours so that just the body is showing and this looks like the best way. I had originally planned to have a dropped shelf for it and then slide it in from underneath. Does the cover sit snugly or are you using some velcro or something? This is going to be my first big project since getting out of Mobile Dynamics earlier this year and I pulled the back seat out of my 65 Chrysler to do it. It will be kind of a resume piece so it has to look super sharp. The guys who painted my car already said they would paint the box for me at no extra charge (I traded them a website for my paint job).

Couple of questions. You call the second part a mold. Does that mean you glass the inside of it and then dump the mold, or do you glass the outside of it and dump the stuff from inside like the foil? Also how do you run the speaker wire in to the box so it looks the best. I can not see that angle in the photos. Any additional tips and/or photos would be helpful. I have converted your article in to a nice pdf document for myself and enlarged the photos for clarity. I plan on adding it to my personal reference library. You rock VM!

Hi, I am new to this site as you can see and I am loving the amount of detail that the membere here post.... But anyways, just a quick couple of questions about the encloseure that you built, 1. What is the reason for the cover that you built, can you paint on the original enclosure or do you heed to make the cover to put over the box in order to paint, from what I am thinking , it seems like the reason for it is for less sanding and preo time... But dont know for sure. 2. Did you put fiberglass on the sides of the enclosre and on the bottom???? 3. Is there any need for some wood screws for the braces or is wood glue and super glue addaquate???? 4. What is the general cost on just the fiberglass materials... Minus paint, mdf, etc. just like resins and mat and other needs for fiberglassing only, plus roughly how much resin and matt did you end up using for this project, im assuming alot by the looks of it.... 5. Is there any internet websites on where I can purchase all of this, I've read that home depot has some stuff, never looked, but from what I read it was elmers brand, is that any good???? I know of autobodydepot.com, which is a great site for paint and abrasive needs,but never came accros fibergalss stuff, maybe i wasnt looking hard enough... But thanks alot!!!! Thanks alot for your time and this forum has helped my mind out greatly!!!!!
