- This is our first video of a 2 part series. In this video we go over the basic setup and shaping of an enclosure that shows how we get it to the stage people get a visual on. This was made in about 30 minutes but it will teach you the basics. Please use MDF or Birch Plywood and not the OSB , this was just a DEMO of how it is done.

I now have links to the resin product I use in the description of the video.
Forget the haters. This video changed my life, thank you sir
I hope it gave you what you needed to know to do your project your way. Thanks for the kind comment.
Yup, me too. I’ve been fiberglassing and using all types of resin based products, even resin impregnated carbon fiber. I’ve never seen fabric-cation as I’m now calling it.
Great vid...you have so much to offer...thanks for sharing
spraywaaaaaaay!!!!
Watching this whole series,good stuff thanks!
Thanks , hope you enjoy it and any steps not covered in this should be covered in our new video How to fiberglass speakers on your motorcycle, shows a few more finishing steps that we did not cover in the first video.
Dude thank you for this video !
I had no idea that fabric was used in this process. It's a good thing Shane had some left over. lol Too funny!
Now that OSB is worth its weight in gold, you can make some major profits off that setup.
Tru story. I'd never thought I'd see stuff at 50.00 a sheet.
after 2 minutes of hearing about osb ...I almost stopped the video...actually said out loud "we get it...you normally wouldn't use osb...get on with it"!
Lesson learned.
GSyn eminiDrome same here!!!!
If your camera has a mic input, I'd suggest a Rode Mic or a wireless lav mic. Good video. Cheers
Thanks for the suggestion, and yes we have moved to a Wireless BT mic from Sony. Loving it, about 130 bucks but so well worth it.
Nice! Well, let us know if you ever need tips or suggestions about your Channel. We're *TH-cam Ambassadors* for Latin America, but we're in Arizona and will gladly help you if needed. (Our help is free, of course). Best of luck!
+FC Autos and we surely love the advice. Want the channel to feel like it's for the people. And any suggestions are welcome. Thanks a bunch.
Just sent you a DM.
What if i tell you...
There are other brands than RØDE? 😱😱😱
How do you know what the box is tuned to with a seemingly arbitrary port setup? The materials, port size, length, shape, etc all contribute greatly to the sound the enclosure makes.
Exactly 😂 this is not how to make a subwoofer box guys don't do this please
So what is the fabric you use for wrapping called?
So you can basically use most any material that can stretch? I've seen others use a kids blanket.
hello there. what type of cloth are you using? any other alternatives?
about the resin. how did you use it?
We get it its a quick demonstration!!!!
I know, I overdid, first video and my pride was the reason I kept saying that. Thanks for watching and believe it or not we do have new videos coming. Been awhile but we are coming back.
Random Audio Guy you did a great job it was a nice video honestly i just wanted to give u a hard time lol
So would you typically use that OSB or would you recommend a different material?
MDF tends to be the best choice for working with fiberglass and subwoofers, I just used it as a means to make the video.
Lol
Is cheapest for the project
Lol 😂
I'm thinking of making them with 3 sub woofers inside the trunk and some 6x9's in doors an tweeter s on front next to windshield then be sick to put in my ford with neon light to run with stereo
Aren’t you supposed to use 3/4” MDF for subwoofer boxes? I see some people use plywood. What’s the difference?
what kind of fabric do you use? fleece fabric?
I was high when I watched this. About every 2 minutes I kept trying to turn the volume up. No luck.
Fair enough. First video we uploaded. Learned alot about the audio levels since then, try out some of our new videos.
Hahaha Me 2...
You didnt by chance go to R.I.T.O.P. in Boston ? I learned to to this exactly like this there. A long time ago that is.
How do you calculate air space and port length for these types of enclosures? Also, what about the corner of the port that drops down (back corner at port turn)? Is this accounted for as well?
The best way to determine air volume of a fiberglass box is Sand or for most people a more readily available product is packing peanuts. You fill up the volume once you have it shaped and then pour that into a 12x12x12 cardboard box until you fill it up with the total amount and lets say you ended with 2.2 boxes of packing peanuts then you have a very close idea to your total volume of airspace. If at this point you need to make adjustments to the port you do it then before you start putting on resin.
I hope that makes sense enough for you, Its hard to put into words something that is so easy to do but hard to word it out. Maybe ill cover this in a future video, plan on alot more fiberglassing coming and now that we are through remote start season new videos should roll in a bit faster so Ill try to remember this and cover it for you.
PS, yes the port curve on the top is accounted for in this box. And if you go for a tune of 32 hz, you might end up with 33 or even 31 but you will be very close either way.
Makes sense. Thanks!
What wrap do i use can u show link for it im trying to make a box
I wish I could do a link but the way I buy my fabric is to go to a local big box retailer like Walmart and I go into the fabric section and start stretching frabic until I find something that suits my needs.
thumbsUP!
I just need to know how to find volume before i make a custom corner trunk box for a 15 i know i can use packing peanuts so what I count out how many I need for the box to be perfect and then place it where I want the box to be and get a good idea on how big I need it or what
You build your volume and then you fill it with packing peanuts. Once its full you pour that into a 12x12x12 cardboard box and that measures out your cf.
@@RandomAudioGuys right but i like to know how to build it for a specific sub
Question (possibly dumb)...is the fabric necessary? Can you apply the fiberglass over a carpet speaker box? Or would the carpet need to be removed and then a fabric over a bare box? Thanks.
Im not sure exactly why a person would want to do that unless your building off a box that is already built, Then yes you could put resin on the carpet and let it harden them build off that.
Yeah I have a custom box for my 2018 Challenger and thought about giving it a try with fiberglass instead of building a new box. I’ll give it a whirl. Thanks man.
I’m going to build a sound bar for the jeep using your methods I have a few questions if you have time to answer. One is if I wanna put subs and mid range with tweeters do I have to block the subs completely as if they were incased then build the others together. If I do should I have ports for just the sub enclosure or all three parts. Sorry kinda new to the speaker side of building. I found two 6.6 600wt 300rms subs to use and think they may sound pretty cool that way. And second question would be would this have to be wired to an amp then the jeep or could use bridge that rite into the original sound bar plug. Any ideas or suggestions would be awesome. And I can share what I come up with
That will be a really large soundbar if you try to intertgrate the subwoofers into it with the mids and highs , But yes if you did do that you would want to seperate the subwoofers from the mids as it would beat them to death quickly.
I would do a sound bar and put the subwoofer somewhere else, Just my opinion.
You would want to run this off its own amplifier, as the factory radio will not make enough power to push a good sound bar, Doesnt really do a good job of pushing the stock sound bar in my honest opinion.
Id do some good Pro audios, if DD or something like that doesnt fit your budget then maybe look into PRV they offer great mids and highs affordably.
@@RandomAudioGuys awesome I’m only running two small 6.6 subs 600wt 300rms I do wanna do big loud subs but as it’s a jeep that I’ll have to build into the jeep and water proofing and lots of research lol. I was thinking about integrating a center console sub too but that’s down the road this is a quick in need of hearing loud sound with the top off and flying down the highway lol. But still same idea separate the subs. Wire them to the amp them the deck. Only question left is and please explain like I’m 4 why are there two sets of terminals on the subs? I’ve never wired them inside a box before just a box into a car once
How do you know what the volume will be before you glass it?
Simple shapes like this can be measured similair to a normal wood box, More complicated shapes I will typically use Aero ports and things where I can adjust them once I have the airspace.
I'd never use osb for subfloors. some do but I will not. it's ok for wall sheathing but only ok.
Hi Random,Got a question and sort of in a pickle.I'm glassing a spare tire well and on the front and sides where the wood meets the sheet metal there are small gaps.Will the resin and chop mat fill that in just fine or is there another way to deal with small gaps?
Assuming you mask the area off that you are working in. And if I am picturing what you are saying right then as you brush resin onto the chop mat you take you tools and slowly work it into the area and it fills these voids. Again Im hoping I am picturing this correctly.
Random Audio Guy Thank you...I'll do my best to maybe fill the back side of the gap with the painters tape so that the resin has a pocket.
Random Audio Guy I can send you an exact picture of what I mean if you shoot me your email.You could send me an email at 1pocket73@sbcglobal.net and I could return the picture.Much appreciated the way you are always willing to help.
Your able to reach me on Instragram @randomaudioguy
Where do u guys buy those rings at
I tried finding this Purple blanket on the website you provided but the only ones I'm seeing are white is there any way you can tell me how to get it... and if its s2 glass or if its plain weave e glass..etc...those are the polyester fabrics I found on there but are white
Bigblu Blue the purple is just a random stretchy fabric I use to get shape. Then I apply resin to harden that shape and build fiberglass on it.
Random Audio Guy thank you for the reply ....so that resin will harden that purple material for shape..I asked because I've seen same purple blanket in other videos and then you apply the fiberglass mat for the harder feel and then the fiber blanket over it all for smoother surface
Yes depending on the object your working on. Typically we get to work on the outside surface. I use other techniques where I use the inside and build it strong from that direction. Makes it a lot easier to finish that way but its not always a choice. Depends on the shape and object your doing.
Random Audio Guy sorry to bug you.. do you have the link to the resin , filler etc you used...I seem to not find it ...thanks again for all your help
In one of the videos on this box I have the fiberglass resin link in the description box.
Where can I find that fabric
Epoxy and baking soda works great too
is the curved & straight edges on the "port corner" intentional or just because it's a quick demo?
Intentional, front side = the exit of air, softens the blow much like a Flare on a aero port.
PS, very good observation to catch that.
what kind of fabric is it ?
Do you have a shop? If so, where is it located?
Stop worrying about the osb brother. You’re teaching people something if they can’t understand that the need to find a different hobby because the work will be over their head. Thanks for the video.
Just to clarify regular OSB is not for subfloors. It’s for sheathing and roof decking.
Subfloor osb is actually wax impregnated which makes it water proof and it is a much more dense product that holds screws well. . I actually like it better than birch or MDF
Interesting enough I did some box testing using Avantech and it did have some good results in the strength area.
Random Audio Guy in your testing were there acoustic issues?
Does Home Depot sell descent resin and chop mat? I was looking at US Composites online but if I could save the shipping costs I'd rather pick it up from a local HD.
The resins sold at big box retailers are typically bottom of the barrell type stuff. Cheap and in my opinion garbage. Sure we have all used it before but I get it online at a store that requires you buy 125.00 to get free shipping.
What fabric is that?
lol. this is pretty darn awesome. Learning alot. Thanks... FYI- I look pretty darn sexy in my blue dress.... NOT!!! lol
Background song in beginning?
wat is the cloth over the speaker call so many kinds
That was just a normal fleece in this video. I use different types of fabrics but Fleece tends to give the best shaping stretch. If you do not have a lot of shape in your project you can used unbacked speaker box carpet and get a lot of strength.
where can u buy it from
wat I'm asking can u use any kind off fabric when fiberglassing. things
You can buy it on Amazon. As for what cloth there is really not 1 any certain cloth required, If it stretches and can give you the shape your looking for thats the one you want to use. I cannot think of any cloth that has a bad reaction to fiberglass resin, I do know Terry Cloth doesnt do well. It stretches but is very brittle once it sets up so try to stay away from that.
Take a trip to your local walmart or what you have like them that carries fabric and hit the close out sections, I usually get my fabrics for a dollar or two per yard.
with the rings... if I were to have a 12' sub.. what would the outside of the ring be compared to the inside? would it be 12' on the outside or would the inside of the ring be 12'?
The hole cutout for most 12 inch subwoofers is 11 1/8th inch. So your Ring would be in the neighborhood of 12 to 12 and half on the outside. Just depends on which subwoofers your using. I like my Rings to be at least 1 inch but on the newer projects were working on you will see where we build 2 rings and attach them together so the subwoofer is countersunk into the box.
Hope that helps and stay tuned we got more coming, Just had a cold winter so I was stuck with remote starts, got a few videos filmed though, Just got to get them edited and up on the channel.
Yeah, I'll definitely be watching. So the actual circumference of the outside of the ring will be 12 and a half, and the inside measured at 12' for the sub to sit flush?
Depends on the subwoofer, Most subwoofers actually are about 12 1/2, So if I wanted to do a flush I would have 1 ring normal 11 1/8th hole to 14, then the top ring would be lets say 12 1/2 to 14, so they flush up together , glue them and sub sits inside one but has a landing to lay on for the second one.
Cool, but why'd ya use Osb?..🤔
😅
The fabric used is called
Fleece
Where u work out of. U have a shop
Kentucky and yes.
Is this normal velvet clothe?
Polyester fabric. Stretches in 1 direction and a little in the other. Great for this type of project.
Don't worry. You said it was for demonstration. If people have an issue with it, fuck them. You're doing people a favor showing them a demonstration!
Hello de you have measurrments?
24 Wide 12 deep 12 tall
+Random Audio Guy ok. thank.
Lmfao he used to make his own dresses😂💀
Best one which is the easy like on my video
We get this is temp we get that it's not suggested to use osb.
12:24 this is cotton cloth or other?
Cotton works great.
@@RandomAudioGuys and what you use company all products for paint this Can you give me website?
Dalrods and hot glue gun works better for putting in place
Sorta, You are right in the sense they work, we use them alot. The problem is with a box like this getting 2 rings positioned correctly and aligned is alot harder to do. If I am building an all fiberglassbox in a real situation then you probaly would have seen dowel rods.
Chris Neal l
Build with mdf its a stronger Wood this wood Will not hold a bas
I believe I mentioned it multiple times in the video that the wood used was for an example how to do it and to not use OSB, to use mdf or birch.
Hey next time can you lower the volume a little more? I can almost hear whats going on.
exposer dozer Hey man I get that shit alot. It was the Mic I used at the time you'll see our new videos have much better audio. that was my second edit. I know it's rough but we will have more Fiberglass coming and you'll see a whole world of difference. forgive a brother, first video but it'd enough to learn from so it does what it was intended to do.
promise I got you come the next Fiberglass video.
Man I really want to watch this video I have my volume in my car turned up all the way I just can't hear you
I understand. I may go back and rereleased this video with louder audio. Was new to the program I used.
it looks l ike a great video but i cant hear you even with the volume turned up :
First video I done. Since then I have gotten a better mic to record worth. Will be doing future videos on the same subject, just the time of the year where we are doing remote starts everyday and I have not gotten a video up. Hoping to have one up in the next week.
That would be wonderful thanks 😄
What's remote starts though?
They make your car start with the press of a button. So they warm up for you before you head out in the morning. Very popular item this time of the year.
Ohhh gotcha. I could really use that tbh.
The fabric used is called I was not listening, not Thailand. I read English
Hi
Polyester fabric.
Y dd u use that kind of wood dude
These are my favorite comments on the internet. It's like noone proof reads anything.
CAN'T HEAR THE AUDIO.
SPEAK UP CANT HEAR YOU!!
Could barely hear what was said...
Awesome man! Check out my sub box build for my cutlass
lmao
its a square not a ”triangle”
Figure out your sound... TV is set 96 out of 100 and can barely hear you.
Hey great video but this is not fiberglass!
Watch part 2 of the video.
Audio is horrible. Wish I could hear it
Dude fix the audio
What's the point of making a video no-one can hear!!!
To piss people off like you. Or you can see we purchased a new mic for our videos. That was our second video we made and we realized we had mic issues so I invested in a 150.00 Mic to help with the issue. You could have just said hey man your audio sucks on this video , fix it in the next. Or you can check the newer videos and realize it was fixed, either way you want to approach it is fine. Just expect the reply to fit accordingly.
Using OSB Board??? Lmao
Makes no sense because if your making that comment you would know I said I am only using it for a quick demonstration but to never use it for an audio product.
volume sucks
Yeah sorry about that first video we posted, Switched to a Sony Bluetooth mic and its helped alot. Some times Ill also grab video with my phone which doesnt help. Still a learning curve but hopfully you see the videos get better.
I cant hear a thing. Please post better sounding vids. I stopped b/c of this.
Rough as f#¥k!!!!!!
Your audio in this video is terrible. I can barely hear what you're saying.
The sound on this video is terrible. Was someone asleep next to you or what?
6 min in and noyhing. still talking bout how im gonna get this basics. this could have been a 6 min video if he got to the dam point.
Thanks for the view. Sorry your attention span is too short to take in what it takes to do fiberglass. Ps, first TH-cam video I ever made.
Whoa, great video! . What do you think a shop should charge to build a custom box like you so expertly showed here? How much does it cost for the parts and product needed to build the box, and how long would u say is the total time it took you to build it. Its hard to tell as its on TH-cam and all the video editing. I was thinking about doing this myself, im capable, but lack the garage and tools, im not very handy but am a fast learner. U r a pro, can a novice do it yourself, or is it too difficult? What do you think?
Thanks! Jeff
6 hours of work time. 75 to 125 material cost.
Each market decides what they can get out of it but a shop should be building multiples at a time to keep cost down.
And easily a diy project as I find those people tend to dedicate more time to it.
Is this a joke?
To much talk😡😡😡
I think you have thrown out enough excuses of why you're doing what you're doing
I clicked on this video just to give the thumbs down for the thumbnail...... Get a better thumbnail bra
