Either they do not have enough pictures or do not clarify it correctly. In this overview I am mosting likely to provide you the In’s as well as Out’s of Making a personalized fiberglass subwoofer box. I have chosen to make a sub box for my Honda Overture. I am going to be setting up a JL Audio W3V3 with a 500 watt Towering Amplifier.

Fiberglass Below Box:.

Ok, time to start making a fiberglass sub box! The very first step to making package is drawing out some intend on what you desire and 原理原則のコンテンツseo exactly how to you wish to do it. When fiberglassing, you can’t really fix your mistakes due to the fact that when fiberglass resin is completely dry, its DRY.

We wanted to make a straightforward box that would certainly conserve space, as well as look oem to the prelude. We began by laying covering up tape down so no fiberglass material jumps on the carpeting, due to the fact that if it does, its messed up. Additionally, make certain to tape added area after that your in fact mosting likely to make use of simply to be safe.

We did concerning 2-3 layers of tape and then also included some aluminum foil as a layer, regarding not get any kind of glass on the carpeting. When you think that you have sufficient tape and also there is no feasible way that anymore fiberglass could get across the carpeting; do one more layer.

The next step after you have touched everything is to begin fiberglassing. Prior to you blend your fiberglass with your hardener, you must cut strips out of your fiberglass mat. I generally 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 just how much fiberglass resin to hardener mix to make. Make sure you prepare before you begin fiberglassing due to the fact that it dries out somewhat quick. Repaint a layer of fiberglass resin onto the tape without any floor covering. After you’ve painted a layer put fiberglass mat down as well as repaint an additional layer over fiberglass afterwards. Wait regarding 10 minutes and afterwards do one more layer before it dries out totally.

Currently, wait a minimum of a hr and also allow the fiberglass resin completely 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 draw out where you wish to remove. Make sure you go gradually and also don’t take all of it off simultaneously.

Currently you need to eliminate a MDF ring for your speaker to screw into. Some choose to make a flush ring with a router however I such as the one ring means much better. I am making use of a 10 inch jl audio w3 so I cut out a 10 inch ring and made use of the specs from package to make a ring the ideal dimension.

Then we pulled out our freshly trimmed fiberglass box as well as placed one more layer of fiberglass floor covering on it. Normally you wish to do about 5-6 layers of fiberglass. Some claim you should have the ability to base on your box without it breaking. One more great fiberglassing idea is to get rid of as lots of air bubbles as feasible. This will make the mold a whole lot stronger since there’s no air pockets. You do this by jabbing the fiberglass instead of in fact attempting to paint it.

Ok, adequate playing around; back to fiberglassing! Next we placed on a last layer of fiberglass floor covering as well as material. After this has completely dried (about 3 hrs) we started fining sand and also reducing to obtain the shape we wanted with our personalized fiberglass below box.

When your back mold and mildew looks great to you its time to establish your MDF phone how to desire your sub to be. Hold your call where you believe you would certainly like it. Cut some dowel poles to dimension and position your ring how you desire it. We utilized superglue as well as epoxy to keep the dowel rods and the MDF ring in location. Its vital that your ring is very solid and also tough because we are going to stretch fleece over it.

Make certain that when your ring is in area every angle looks good and also to you. When you extend the fiberglass as well as begin painting resin on it, there’s no turning back.

Now is the fun part. This is where your fiberglass speaker box begins ahead together. Order your fleece as well as stretch it over your mold and mildew you have actually made. Make certain to extend it as limited as possible so there are no folds or loosened components. The fleece must be touching every side of the back of the fiberglass mold.

Make use of a staple gun to safeguard 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 permanently.

Once you believe its done look it over once more from all side as well as ensure it looks how you desire it to look because when the fiberglass material is on, its that form permanently.

When every little thing looks good to go, its time to start glassing. Mix a good quantity of fiberglass (regarding 12 oz) and also repaint the fiberglass over the fleece. Repaint it on thick, as well as see to it to copulate to the edge so you mold and mildew the two items (front and also back) with each other. There’s no demand to repaint the whole ring due to the fact that we are mosting likely to cut it out anyway. Do fiberglass the fleece to the MDF ring.

Once its dry (took around an hour since we utilized a great deal of glass) you can cut off the accessibility fleece from the edge of the mold and mildew and also around the ring. Right now you must have the ability to pull the dowel rods out of package and the ring must remain where it is. Once you’ve trimmed off the bulk extra of the fleece, toss the box in your automobile and see exactly how it looks. Looks pretty good here!

Not to screw up the external form 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 sure to fiberglass in between where the two mold and mildews integrated.

When you end up the inside of the box venture out the sander and the jig saw and also cut off all the excess crap around your fiberglass box. We are going to make use of carpet on our box, so we do not require to sand the really fiberglass mold and mildew. Rather we simply sand all the edges and also edges so it fits snug right into the trunk of the Honda Start.
