I’ve seen numerous fiberglass speaker guides that show how to make a custom-made fiberglass below box. None of these guides have actually clarified exactly how specifically to do it. Either they don’t have sufficient pictures or do not clarify it appropriately. In this guide I am mosting likely to give you the In’s and also Out’s of Making a custom fiberglass subwoofer box. I have made a decision to make a sub box for my Honda Overture. I am mosting likely to be mounting a JL Audio W3V3 with a 500 watt Alpine Amplifier.

Fiberglass Below Box:.

Ok, time to begin making a fiberglass sub box! The primary step to making the box is extracting some intend on what you desire and how to you wish to do it. When fiberglassing, you can not truly repair your errors because when fiberglass material is dry, its DRY.

We intended to make an easy box that would conserve space, and look oem to the start. We started by laying covering up tape down so no fiberglass material jumps on the carpet, because if it does, its wrecked. Also, make certain to tape additional area then your actually mosting likely to utilize just to be risk-free.

We did about 2-3 layers of tape and afterwards also included some aluminum foil as a layer, as to not get any glass on the rug. When you think that you have enough tape as well as there is no feasible manner in which anymore fiberglass could get across 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 must cut strips out of your fiberglass floor covering. I normally make strips about 7-9 inches wide. When you prepare, what you need to do is mix your fiberglass with your hardener in the mixing mug. The hardener will have how much fiberglass material to hardener mix to make. Ensure you prepare prior to you begin fiberglassing since it dries rather quick. Paint a layer of fiberglass material onto the tape with no mat. After you’ve repainted a layer placed fiberglass mat down as well as repaint an additional layer over fiberglass afterwards. Wait concerning 10 minutes and then do an additional layer before it dries out totally.

Now, wait at the very least an hour as well as allow the fiberglass resin totally dry. When its dry, you can take the mold and mildew out as well as tear off all the tape and aluminum foil. Put it back in your trunk as well as extract where you wish to cut off. See to it you go slowly and also do not take all of it off at once.

Now you need to eliminate a MDF ring for your speaker to screw right 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 audio w3 so I removed a 10 inch ring and also used the specifications from package to make a ring the ideal dimension.

After that we took out our newly trimmed fiberglass box and placed another layer of fiberglass mat on it. Normally you intend to do regarding 5-6 layers of fiberglass. Some claim you ought to be able to base on your box without it breaking. Another excellent fiberglassing idea is to remove as several air bubbles as feasible. This will make the mold a great deal stronger since there’s no air pockets. You do this by jabbing the fiberglass as opposed to in fact attempting to paint it.

Ok, adequate messing around; back to fiberglassing! Next we put on a last layer of fiberglass mat as well as resin. After this has totally dried (about 3 hours) we started sanding and also reducing to get the form we desired with our custom fiberglass sub box.

When your back mold and mildew looks excellent to you its time to establish your MDF ring up exactly how to want 原理原則のコンテンツseo your sub to be. Hold your ring up where you assume you would like it. Cut some dowel rods to dimension and place your ring just how you desire it. We made use of superglue and epoxy to maintain the dowel rods and also the MDF ring in place. Its essential that your ring is very solid as well as strong due to the fact that we are mosting likely to extend fleece over it.

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

Now is the enjoyable component. This is where your fiberglass subwoofer box starts ahead together. Order your fleece and stretch it over your mold and mildew you have made. Make certain to stretch it as tight as feasible so there are no folds or loosened parts. The fleece should be touching every edge of the rear of the fiberglass mold.

Make use of a staple weapon to safeguard the fleece to the speaker fiberglass mold. Staple the staples in the side of the fiberglass box so you don’t fiberglass over them and also have them be stuck permanently.

As soon as you believe its done appearance it over again from all side and see to it looks exactly how you want it to look because as soon as the fiberglass resin is on, its that shape permanently.

When everything looks great to go, its time to begin glassing. Mix an excellent amount of fiberglass (about 12 oz) and repaint the fiberglass over the fleece. Paint it on thick, as well as make sure to go all the way to the edge so you mold and mildew both pieces (front and back) with each other. There’s no requirement to repaint the entire ring due to the fact that we are mosting likely to quit anyhow. Do fiberglass the fleece to the MDF ring.

When its dry (took around a hr because we utilized a lot of glass) you can cut off the accessibility fleece from the side of the mold and mildew and around the ring. Currently you need to have the ability to draw the dowel rods out of package as well as the ring should stay where it is. Once you’ve trimmed off the mass excess of the fleece, throw the box in your car and also see how it looks. Looks respectable right here!

Not to screw up the external form of our fiberglass sub box, we require to add the remainder of our fiberglass layers to the inside of the box. Add about 2-3 layers of fiberglass mat to the within the mold and mildew. See to it to fiberglass in between where both molds collaborated.

As soon as you finish the inside of the box go out the sander and the jig saw and also cut off 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 really fiberglass mold. Instead we simply sand all the edges as well as edges so it fits snug right into the trunk of the Honda Overture.
