Honda Prelude Fiberglass Subwoofer Box

Executive Summary by Tyler Horvath

 

I’ve seen many fiberglass subwoofer guides that show how to make a custom fiberglass sub box.

Custom Fiberglass Subwoofer Box:

Materials:

1 Gallon of Fiberglass Resin (find at Auto Zone, Advanced Auto Parts, Etc)

Cheap Paint Brushes (probably about 10; you will throw away after each use)

Rubber Gloves for fiberglassing

Fiberglass mat (about 6-8 packages depending on the size of your box)

MDF Wood 1/2?

2 Dowel Rods

2 Rolls of Masking Tape

Aluminum Foil

Cheap Mixing Cups

1-2 sq yards of fleece (hobby lobby)

Fiberglass Sub Box:

Ok, time to start making a fiberglass sub box! When fiberglassing, you can’t really fix your mistakes because when fiberglass resin is dry, its DRY.

Before you mix your fiberglass with your hardner, you should cut strips out of your fiberglass mat. The hardener will have how much fiberglass resin to hardener mix to make. Paint a layer of fiberglass resin onto the tape without any mat. After you’ve painted a layer put fiberglass mat down and paint another layer over fiberglass after that.

I am using a 10 inch jl audio w3 so I cut out a 10 inch ring and used the specs from the box to make a ring the right size. Then we pulled out our newly trimed fiberglass box and put another layer of fiberglass mat on it. Generally you want to do about 5-6 layers of fiberglass.

Next we put on a last layer of fiberglass mat and resin. Cut some dowel rods to size and position your ring how you want it. The fleece should be touching every edge of the back of the fiberglass mold.

Use a staple gun to secure the fleece to the subwoofer fiberglass mold. Staple the staples in the side of the fiberglass box so you don’t fiberglass over them and have them be stuck forever.

Mix a good amount of fiberglass (about 12 oz) and paint the fiberglass over the fleece. Do fiberglass the fleece to the mdf ring.

Not to mess up the outter shape of our fiberglass sub box, we need to add the rest of our fiberglass layers to the inside of the box. Add about 2-3 layers of fiberglass mat to the inside of the mold.

We are going to use carpet on our box, so we do not need to sand the actually fiberglass mold. If you are wanting to paint your custom fiberglass subwoofer box, you will need to get some bondo and a lot of sand paper to smooth out the fiberglass sub mold.
