Hey, this is Rob from Art of Noise Audio. I build custom fiberglass enclosures for Magnums and other cars. I've seen a lot of interest from people who want to take on the project themselves, so I decided to write a how-to. I usually build my enclosures from molds that I've made of the rear pockets, but I made this one from scratch to show how you could do it. This project is not for the beginner, and if you aren't good with working with your hands, it might be best to get a local shop to do the work. I also offer enclosures for sale and you can email me at [email protected] for more information.
Ok, so here goes. The first thing you need is patience. Anyone can make a work of art, but you can't rush anything. Every step builds off the step before, so take your time and do each step to your best ability.
I used:
2" Blue Painters Tape (not the green, trust me)
Tin Foil
Plastic Drop Cloth
Scissors
Razor Knife
Tape Measurer
Sharpie
Respirator
Dust Mask
Vinyl Gloves
Power Drill
Hot Glue Gun
Air Compressor
Cut-off Wheel
Knurled Bit
D/A sander w/ 40 grit pad
Router w/ circle jig or Jig Saw
40 grit 9"x11" sand paper
2"x4" x11" wood block
2" Disposable Paint Brushes
Bondo Spreaders
Containers
Materials:
1.5 oz. Fiberglass Mat, approx. 38"x 2 yards
Fiberglass Resin, approx. 1 gallon
Body Filler, 1/2 gallon Z-Grip
Tee Shirt Fabric or Fleece
3/4" wood, MDF or a hard plywood
Wooden Dowels
The first thing to do is tape off the Pocket. I use tin foil for the big surfaces, and tape to cover all the seams.
When I taped the pocket, I didn't tape the the front and rear bottom corners and the top corner. Instead I used a piece of tin foil to bridge across them. If I taped tight into the corner, the enclosure would not be able to slide in and out easily when it is finished.
And then cover the floor with a drop plastic.
Now it is time to cut the fiberglass pieces. I cut them to overlap each other and to be bigger than I want the final enclosure to be. It's easier to trim more off than to add more on.
