Fiberglass Front Doors: Making An Entrance

I have actually seen many fiberglass subwoofer overviews that show how to make a custom-made fiberglass below box. None of these guides have actually clarified just how exactly to do it. Either they don’t have sufficient pictures or do not clarify it appropriately. In this guide I am going to offer you the In’s and also Out’s of Making a custom fiberglass subwoofer box. I have actually determined to make a sub box for my Honda Prelude. I am mosting likely to be installing a JL Audio W3V3 with a 500 watt Alpine Amplifier.

Personalized Fiberglass Speaker Box:


1 Gallon of Fiberglass Resin (locate at Vehicle Area, Advanced Auto Components, Etc).

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

Rubber Hand protection for fiberglassing.

Fiberglass floor covering (about 6-8 packages relying on the size of your box).

MDF Wood 1/2?

2 Dowel Rods.

2 Rolls of Masking Tape.

Light weight aluminum Foil.

Inexpensive Mixing Mugs.

1-2 sq lawns of fleece (leisure activity entrance hall).

Fiberglass Sub Box:.

Ok, time to start making a fiberglass below box! The primary step to making the box is drawing out some intend on what you want as well as exactly how to you want to do it. When fiberglassing, you can’t actually fix your errors due to the fact that when fiberglass material is dry, its DRY.

We intended to make a simple box that would certainly conserve room, as well as look oem to the start. We began by laying covering up tape down so no fiberglass material jumps on the rug, due to the fact that if it does, its messed up. Also, ensure to tape extra area then your actually mosting likely to use just to be safe.

We did concerning 2-3 layers of tape and then additionally included some aluminum foil as a layer, regarding not obtain any glass on the carpet. When you believe that you have sufficient tape and there is no possible manner in which anymore fiberglass might get through to the carpeting; do an additional layer.

The next action after you have actually touched everything is to start fiberglassing. Before you mix your fiberglass with your hardener, you need to reduce strips out of your fiberglass floor covering. I typically make strips about 7-9 inches wide. When you prepare, what you need to do is blend your fiberglass with your hardener in the mixing mug. The hardener will certainly have how much fiberglass material to hardener mix to make. Ensure you prepare before you start fiberglassing since it dries somewhat quick. Repaint a layer of fiberglass resin onto the tape without any mat. After you’ve painted a layer placed fiberglass mat down as well as paint an additional layer over fiberglass afterwards. Wait concerning 10 minutes and afterwards do another layer prior to it dries totally.

Now, wait a minimum of an hour and allow the fiberglass material completely dry. When its completely dry, you can take the mold out and detach all the tape and aluminum foil. Place it back in your trunk and also extract where you want to remove. Make sure you go slowly as well as do not take all of it off at the same time.

Currently you need to cut out a MDF ring for your speaker to screw into. Some like to make a flush ring with a router yet I like the one ring method better. I am utilizing a 10 inch jl sound w3 so I eliminated a 10 inch ring as well as utilized the specs from package to make a ring the best dimension.

Then we pulled out our recently cut fiberglass box as well as put another layer of fiberglass mat on it. Generally you intend to do about 5-6 layers of fiberglass. Some claim you ought to have the ability to stand on your box without it breaking. An additional good fiberglassing idea is to get rid of as lots of air bubbles as possible. This will make the mold a whole lot more powerful because there’s no air pockets. You do this by stabbing the fiberglass as opposed to in fact trying to repaint it.

Ok, sufficient messing around; back to fiberglassing! Next we put on a last layer of fiberglass floor covering and material. Hereafter has totally dried (concerning 3 hours) we began sanding and reducing to get the shape we wanted with our custom-made fiberglass below box.

When your back mold looks excellent to you its time to set your MDF ring up exactly how to want your sub to be. Hold your call where you believe you would like it. Cut some dowel poles to size and place your ring how you desire it. We used superglue and epoxy to keep the dowel rods and the MDF ring in location. Its crucial that your ring is extremely strong and also durable since we are mosting likely to stretch fleece over it.

Make certain that when your ring is in location every angle looks good and also to you. When you extend the fiberglass and also start painting material on it, there’s no turning back.

Now is the enjoyable part. This is where your fiberglass speaker box begins 原理原則のコンテンツseo to come with each other. Order your fleece and also stretch it over your mold you have made. Be sure to extend it as limited as feasible so there are no folds or loose components. The fleece should be touching every side of the back of the fiberglass mold and mildew.

Utilize a staple gun to safeguard the fleece to the subwoofer fiberglass mold and mildew. Staple the staples in the side of the fiberglass box so you don’t fiberglass over them as well as have them be stuck permanently.

When you believe its done appearance it over again from all side and also make certain it looks just how you want it to look because as soon as the fiberglass material is on, its that form forever.

When everything looks great to go, its time to start glassing. Mix an excellent amount of fiberglass (concerning 12 oz) and paint the fiberglass over the fleece. Repaint it on thick, and make sure to go all the way to the edge so you mold the two items (front as well as back) with each other. There’s no need to paint the whole ring because we are going to quit anyhow. Do fiberglass the fleece to the MDF ring.

When its dry (took around an hour because we utilized a great deal of glass) you can remove the accessibility fleece from the edge of the mold and mildew as well as 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. As soon as you’ve trimmed off the bulk extra of the fleece, throw package in your car as well as see exactly how it looks. Looks respectable right here!

Not to screw up the external form of our fiberglass sub box, we need to add the rest of our fiberglass layers to the within the box. Include regarding 2-3 layers of fiberglass floor covering to the within the mold. Make certain to fiberglass in between where both mold and mildews collaborated.

When you end up the inside of package venture out the sander as well as the jig saw and removed all the excess crap around your fiberglass box. We are going to use carpeting on our box, so we do not require to sand the actually fiberglass mold. Instead we just sand all the corners and edges so it fits snug right into the trunk of the Honda Overture.
