I’ve seen lots of fiberglass speaker guides that demonstrate how to make a custom-made fiberglass below box. None of these overviews have actually truly described just how exactly to do it. Either they do not have sufficient images or do not clarify it appropriately. In this overview I am going to provide you the In’s and Out’s of Making a customized fiberglass subwoofer box. I have decided to make a below box for my Honda Prelude. I am going to be setting up a JL Audio W3V3 with a 500 watt Alpine Amplifier.
Custom-made Fiberglass Speaker Box:
1 Gallon of Fiberglass Material (locate at Automobile Zone, Advanced Vehicle Parts, And So On).
Affordable Paint Brushes (probably regarding 10; you will certainly discard after each usage).
Rubber Gloves for fiberglassing.
Fiberglass floor covering (about 6-8 packages relying on the size of your box).
MDF Timber 1/2?
2 Dowel Rods.
2 Rolls of Masking Tape.
Light weight aluminum Aluminum foil.
Economical Mixing Mugs.
1-2 sq yards of fleece (hobby lobby).
Fiberglass Below Box:.
Ok, time to begin making a fiberglass below box! The primary step to making package is drawing out some intend on what you want as well as just how to you intend to do it. When fiberglassing, you can not actually fix your mistakes since when fiberglass resin is dry, its DRY.
We intended to make an easy box that would certainly save space, and look oem to the start. We began by laying concealing tape down so no fiberglass material jumps on the carpeting, since if it does, its spoiled. Additionally, make sure to tape additional space then your actually mosting likely to make use of just to be safe.
We did about 2-3 layers of tape and afterwards additionally included some light weight aluminum foil as a layer, regarding not get any kind of glass on the carpet. When you think that you have adequate tape and also there is no feasible manner in which anymore fiberglass might get through to the carpet; do one more layer.
The next action after you have tapped everything is to begin fiberglassing. Prior to you blend your fiberglass with your hardener, you should reduce strips out of your fiberglass floor covering. I usually make strips about 7-9 inches broad. When you prepare, what you need to do is blend your fiberglass with your hardener in the mixing cup. The hardener will certainly have just how much fiberglass material to hardener mix to make. Make sure you prepare before you start fiberglassing because it dries out rather fast. Repaint a layer of fiberglass resin onto the tape without any mat. After you have actually repainted a layer put fiberglass mat down as well as paint an additional layer over fiberglass afterwards. Wait regarding 10 mins and afterwards do one more layer before it dries entirely.
Now, wait at least a hr and also allow the fiberglass resin entirely dry. When its dry, you can take the mold and mildew out and also tear off all the tape as well as aluminum foil. Put it back in your trunk and extract where you want to remove. Make certain you go gradually and don’t take all of it off at the same time.
Now you need to eliminate a MDF ring for your subwoofer 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 cut out a 10 inch ring and also used the specs from the box to make a ring the right size.
Then we pulled out our freshly trimmed fiberglass box and put one more layer of fiberglass floor covering on it. Typically you want to do about 5-6 layers of fiberglass. Some say you ought to have the ability to stand on your box without it damaging. Another excellent fiberglassing suggestion is to remove as many air bubbles as possible. This will make the mold a whole lot stronger since there’s no air pockets. You do this by jabbing the fiberglass as opposed to in fact trying to repaint it.
Ok, enough messing around; back to fiberglassing! Next we put on a last layer of fiberglass floor covering as well as material. Hereafter has completely dried out (concerning 3 hrs) we started fining sand and reducing to obtain the form we desired with our custom fiberglass sub box.
When your back mold and mildew looks great to you its time to set your MDF ring up exactly how to desire your below to be. Hold your ring up where you assume you would certainly like it. Cut some dowel poles to size and place your ring just how you desire it. We utilized superglue and also epoxy to maintain the dowel poles as well as the MDF ring in location. Its vital that your ring is really solid and sturdy due to the fact that we are mosting likely to stretch fleece over it.
Ensure that when your ring is in place every angle looks good and also to you. When you extend the fiberglass and start painting material on it, there’s no turning back.
Currently is the fun component. This is where your fiberglass subwoofer box starts ahead with each other. Grab your fleece as well as stretch it over your mold you have actually made. Make sure to stretch it as tight as possible so there are no folds or loosened components. The fleece should be touching every edge of the back of the fiberglass mold.
Utilize a staple gun to safeguard the fleece to the speaker fiberglass mold and mildew. Staple the staples in the side of the fiberglass box so you don’t fiberglass over them and have them be stuck permanently.
As soon as you believe its done appearance it over once again from all side and see to it looks how you 原理原則のコンテンツseo want it to look because as soon as the fiberglass material is on, its that form forever.
When every little thing looks great to go, its time to begin glassing. Mix a good amount of fiberglass (about 12 oz) and paint the fiberglass over the fleece. Paint it on thick, and see to it to copulate to the side so you mold the two pieces (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.
Once its dry (took about a hr due to the fact that we made use of a great deal of glass) you can cut off the accessibility fleece from the edge of the mold and also around the ring. Currently you must have the ability to pull the dowel rods out of package as well as the ring should remain where it is. As soon as you have actually trimmed off the bulk unwanted of the fleece, throw the box in your cars and truck and also see how it looks. Looks respectable below!
Not to screw up the external form of our fiberglass below box, we require to include the remainder of our fiberglass layers to the inside of package. Add about 2-3 layers of fiberglass floor covering to the within the mold and mildew. See to it to fiberglass in between where the two molds collaborated.
Once 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 mosting likely to make use of carpeting on our box, so we do not need to sand the actually fiberglass mold. Rather we just sand all the corners as well as sides so it fits snug right into the trunk of the Honda Overture.
