I have actually seen several fiberglass speaker guides that show how to make a customized fiberglass sub box. None of these guides have actually really discussed how specifically to do it. Either they don’t have sufficient photos or do not describe it properly. In this overview I am going to give you the In’s as well as Out’s of Making a custom-made fiberglass subwoofer box. I have actually made a decision to make a sub box for my Honda Prelude. I am going to be setting up a JL Sound W3V3 with a 500 watt Alpine Amplifier.
Customized Fiberglass Speaker Box:
1 Gallon of Fiberglass Resin (locate at Auto Zone, Advanced Auto Components, And So On).
Low-cost Paint Brushes (possibly regarding 10; you will discard after each use).
Rubber Hand protection for fiberglassing.
Fiberglass mat (about 6-8 plans relying on the dimension of your box).
MDF Timber 1/2?
2 Dowel Rods.
2 Rolls of Masking Tape.
Light weight aluminum Aluminum foil.
Inexpensive Mixing Mugs.
1-2 sq backyards of fleece (pastime entrance hall).
Fiberglass Sub Box:.
Ok, time to start making a fiberglass below box! The very first step to making the box is drawing out some plans on what you want and how to you want to do it. When fiberglassing, you can not actually fix your errors due to the fact that when fiberglass material is completely dry, its DRY.
We intended to make a simple box that would save area, as well as look oem to the start. We started by laying masking tape down so no fiberglass material hops on the carpet, since if it does, its wrecked. Additionally, make certain to tape added room then your actually going to make use of simply to be safe.
We did concerning 2-3 layers of tape and then likewise included some aluminum foil as a layer, as to not get any glass on the carpeting. When you think that you have sufficient tape and also there is no possible manner in which anymore fiberglass can get across the carpet; do another layer.
The following step after you have actually tapped everything is to start fiberglassing. Before you mix your fiberglass with your hardener, you should reduce strips out of your fiberglass mat. I generally make strips about 7-9 inches broad. When you are ready, what you need to do is mix your fiberglass with your hardener in the blending mug. The hardener will have how much fiberglass resin to hardener mix to make. Make certain you prepare before you begin fiberglassing due to the fact that it dries out somewhat fast. Repaint a layer of fiberglass resin onto the tape without any mat. After you’ve painted a layer put fiberglass mat down and paint one more layer over fiberglass afterwards. Wait about 10 minutes and afterwards do an additional layer before it dries totally.
Currently, wait at the very least an hour and let the fiberglass resin completely dry. When its completely dry, you can take the mold and mildew out and also tear off all the tape and aluminum foil. Place it back in your trunk as well as draw out where you want to remove. Ensure you go gradually and also don’t take all of it off simultaneously.
Now you need to eliminate a MDF ring for your speaker to screw into. Some choose to make a flush ring with a router but I like the one ring means much better. I am making use of a 10 inch jl sound w3 so I eliminated a 10 inch ring and utilized the specifications from package to make a ring the right size.
Then we pulled out our freshly cut fiberglass box and put another layer of fiberglass mat on it. Generally you intend to do regarding 5-6 layers of fiberglass. Some claim you ought to have the ability to depend on your box without it damaging. An additional excellent fiberglassing idea is to eliminate as many air bubbles as feasible. This will certainly make the mold and mildew a lot more powerful since there’s no air pockets. You do this by stabbing the fiberglass instead of in fact attempting to repaint it.
Ok, adequate messing around; back to fiberglassing! Next we put on a last layer of fiberglass floor covering and also material. Hereafter has actually totally dried out 原理原則のコンテンツseo (regarding 3 hrs) we started fining sand and also cutting to obtain the form we wanted with our custom-made fiberglass sub box.
As soon as your back mold looks excellent to you its time to establish your MDF phone just how to desire your below to be. Hold your ring up where you assume you would certainly like it. Cut some dowel rods to dimension and position your ring just how you desire it. We made use of superglue and also epoxy to maintain the dowel poles as well as the MDF ring in place. Its essential that your ring is really solid and strong due to the fact that we are mosting likely to extend fleece over it.
Ensure that when your ring is in area every angle looks great and also even to you. When you stretch the fiberglass and also begin painting material on it, there’s no turning back.
Currently is the fun part. This is where your fiberglass subwoofer box starts to find with each other. Get your fleece and also stretch it over your mold you have actually made. Make sure to stretch it as limited as possible so there are no folds or loose parts. The fleece should be touching every edge of the rear of the fiberglass mold and mildew.
Use a staple weapon 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 also have them be stuck permanently.
Once you assume its done look it over once again from all side and make certain it looks exactly how you desire it to look because as soon as the fiberglass material gets on, its that form forever.
When every little thing looks good to go, its time to begin glassing. Mix a good amount of fiberglass (regarding 12 oz) and also paint the fiberglass over the fleece. Paint it on thick, as well as ensure to go all the way to the side so you mold the two pieces (front and also back) with each other. There’s no need to paint the entire ring since we are going to quit anyway. Do fiberglass the fleece to the MDF ring.
Once its completely dry (took about an hour due to the fact that we used a lot of glass) you can cut off the access fleece from the side of the mold and also around the ring. At this time you should be able to draw the dowel rods out of the box as well as the ring ought to stay where it is. As soon as you have actually cut off the bulk unwanted of the fleece, toss package in your cars and truck and see just how it looks. Looks respectable below!
Not to screw up the external shape of our fiberglass below box, we require to add the rest of our fiberglass layers to the inside of the box. Add about 2-3 layers of fiberglass floor covering to the within the mold. Make certain to fiberglass in between where the two mold and mildews integrated.
As soon as you finish the within package venture out the sander and the jig saw and also removed all the excess crap around your fiberglass box. We are going to use carpet on our box, so we do not require to sand the actually fiberglass mold and mildew. Instead we just sand all the corners and also edges so it fits snug right into the trunk of the Honda Prelude.
