Fiberglass Is the Best

I’ve seen numerous fiberglass subwoofer overviews that demonstrate how to make a custom fiberglass below box. None of these overviews have actually explained exactly how precisely to do it. Either they do not have sufficient pictures or do not discuss it correctly. In this guide I am mosting likely to offer you the In’s and also Out’s of Making a custom-made fiberglass speaker box. I have chosen to make a below box for my Honda Overture. I am mosting likely to be mounting a JL Sound W3V3 with a 500 watt Towering Amplifier.

Customized Fiberglass Subwoofer Box:


1 Gallon of Fiberglass Material (find at Auto Zone, Advanced Car Parts, And So On).

Affordable Paint Brushes (possibly concerning 10; you will certainly discard after each use).

Rubber Gloves for fiberglassing.

Fiberglass floor covering (about 6-8 plans depending upon the dimension of your box).

MDF Timber 1/2?

2 Dowel Rods.

2 Rolls of Masking Tape.

Aluminum Aluminum foil.

Economical Blending Mugs.

1-2 sq backyards of fleece (pastime entrance hall).

Fiberglass Below Box:.

Ok, time to start making a fiberglass sub box! The first step to making the box is extracting some intend on what you desire and just how to you want to do it. When fiberglassing, you can’t actually fix your blunders due to the fact that when fiberglass resin is completely dry, its DRY.

We wished to make an easy box that would certainly conserve area, and also look oem to the prelude. We began by laying masking tape down so no fiberglass material gets on the rug, since if it does, its ruined. Also, make certain to tape additional space then your actually mosting likely to use just to be safe.

We did about 2-3 layers of tape and afterwards additionally added some light weight aluminum foil as a layer, as to not get any kind of glass on the carpet. When you assume that you have enough tape and also there is no possible way that any longer fiberglass could get across the carpet; do one more layer.

The next step after you have actually tapped everything is to begin fiberglassing. Prior to you blend your fiberglass with your hardener, you ought to cut strips out of your fiberglass mat. I usually make strips regarding 7-9 inches large. When you are ready, what you require to do is blend your fiberglass with your hardener in the blending cup. The hardener will certainly have how much fiberglass resin to hardener mix to make. Ensure you prepare prior to you begin fiberglassing because it dries somewhat fast. Repaint a layer of fiberglass resin onto the tape with no mat. After you’ve repainted a layer placed fiberglass mat down and repaint another layer over fiberglass after that. Wait about 10 minutes and afterwards do another layer before it dries out entirely.

Now, wait a minimum of an hour as well as allow the fiberglass resin entirely dry. When its dry, you can take the mold and mildew out and also detach all the tape as well as aluminum foil. Put it back in your trunk and also draw out where you want to cut off. Make certain you go slowly and also do not take all of it off at the same time.

Now you require to eliminate a MDF ring for your subwoofer to screw into. Some prefer to make a flush ring with a router yet I like the one ring method better. I am using a 10 inch jl audio w3 so I eliminated a 10 inch ring as well as made use of the specs from package to make a ring the best size.

After that we took out our freshly cut fiberglass box as well as placed another layer of fiberglass mat on 原理原則のコンテンツseo it. Typically you wish to do regarding 5-6 layers of fiberglass. Some say you ought to have the ability to depend on your box without it breaking. An additional good fiberglassing suggestion is to eliminate as many air bubbles as feasible. This will make the mold a great deal stronger because there’s no air pockets. You do this by stabbing the fiberglass rather than really trying to paint it.

Ok, adequate messing around; back to fiberglassing! Next we put on a last layer of fiberglass mat and resin. After this has completely dried out (regarding 3 hrs) we started fining sand as well as cutting to get the form we wanted with our customized fiberglass below box.

As soon as your back mold looks good to you its time to establish your MDF call exactly how to want your below to be. Hold your phone where you think you would like it. Cut some dowel rods to size and also place your ring exactly how you desire it. We made use of superglue and epoxy to maintain the dowel rods and the MDF ring in place. Its essential that your ring is really solid and durable since we are going to extend fleece over it.

See to it that when your ring remains in place every angle looks excellent as well as also to you. When you extend the fiberglass and start repainting resin on it, there’s no reversing.

Currently is the enjoyable component. This is where your fiberglass speaker box begins to come with each other. Order your fleece and also stretch it over your mold and mildew you have actually made. Make sure to stretch it as tight as possible so there are no folds up or loose components. The fleece ought to be touching every side of the back of the fiberglass mold and mildew.

Use a staple gun to protect the fleece to the subwoofer fiberglass mold. Staple the staples in the side of the fiberglass box so you do not fiberglass over them and have them be stuck permanently.

Once you think its done look it over again from all side as well as see to it looks exactly how you desire it to look because once the fiberglass resin gets on, its that form for life.

When every little thing looks excellent to go, its time to start glassing. Mix a great amount of fiberglass (about 12 oz) and also repaint the fiberglass over the fleece. Repaint it on thick, and also ensure to go all the way to the side so you mold and mildew the two pieces (front and back) with each other. There’s no requirement to repaint the entire ring since we are mosting likely to cut it out anyway. Do fiberglass the fleece to the MDF ring.

When its dry (took about a hr because we made use of a lot of glass) you can cut off the accessibility fleece from the side of the mold and mildew and around the ring. Right now you must have the ability to pull the dowel rods out of package and the ring should remain where it is. When you have actually cut off the bulk extra of the fleece, toss package in your cars and truck as well as see how it looks. Looks respectable here!

Not to mess up the external form of our fiberglass sub box, we require to add the rest of our fiberglass layers to the inside of package. Add about 2-3 layers of fiberglass mat to the inside of the mold and mildew. See to it to fiberglass in between where the two molds came together.

When you finish the within the box get out the sander and the jig saw and also removed all the excess crap around your fiberglass box. We are mosting likely to utilize rug on our box, so we do not need to sand the really fiberglass mold. Instead we just sand all the corners and also edges so it fits snug into the trunk of the Honda Start.
