Mark, great video man. I hope you don't mind me adding a few things. I do lots of fiberglass projects. Sometimes massive builds with lots and lots of power and sometimes 70 and 80 lbs subs. In fiberglass enclosures. I got some coming up soon but video's yet on them. Anyway, I use 3.5 oz matting where ever I can and 1.5 in those hard to get to areas as you said. A few other things. You need to try to do all layers at one time. Don't wait for a layer to harden before you do the second and so on. Also I use 1/4" steel laminated in the layers where you use wooden dowels. This makes the box bullet proof. I just cut the steel into squares and stick them with hot glue as you do the wood dowels. Same method just bigger scale. Just thought your viewers might want to try that. Again not trying to steal your thunder. Just wanted to help.
@@2ndshiftaudio300 8 yrs later but have you ever tried to use chopped fiberglass. I have access to thousands of pounds of fiberglass but it’s the small chopped pieces, just trying to find out if I could use a lot of that instead of the mats?
Great video Mark! Thks for saying hello, listening and offering some feedback yesterday @ SEMA; I truly appreciated it.Your advice about keeping the laminated layers of fiberglass in place until they're cured is spot on! This is critical, and it's important to remember that dry isn't quite the same as cured... The latter takes longer and varies according to ambient temperature (the hotter the faster), so it does help getting a heating infrared light bulb and fixture to heat the fiberglass laminate, being careful to monitor its temperature and not pointing the light to plastic trim in the car... Keep the great videos coming up man!
I’ve done mine fitting into boot of X1. I started with 150G to get into the corners and finished off with 300G weave. Definitely recommend the ridges added using dowels or spare pieces of timber.
fan Friday I love it. I hope you can continue to do this. I can fiberglass I'm not illiterate on the matter, but I couldn't make a living doing it, so this video really helped me. most of the stuff I knew, but adding the dowels as a molded in thing is a really cool trick. thanks. keep the the fab Friday up cause I love it.
Taking your advice thanks tinting has nothing to do with car audio but I tried it screwed it up couple of times now i know how to install it good it's TRUE all you have to do is try and get better as you go experience is always good I'm working on a subwoofer box 2 12" subs hopefully it comes out either way practice makes perfect
Thanks for the videos, you were one of the references I drew on when building my first fibreglass sub box. It is doing a great job while allowing me to keep most of the trunk space which is far better than needing to shift a big box in and out when you need the space.
your quote at the end sums it up. just go try it and learn! I'm taking your advice and going to start on my first fiberglass enclosure. been getting pretty good with mdf building but I want to take it to next level. thanks so much for all the info !
Awesome video.. This answered a few questions I had.. I have a big project I'm going to do with my ford ranger.. This video probably just saved me from having to re-do my sub enclosures
I've had very good results using strips of angle-aluminum to reinforce fiberglass structures. They're inexpensive, light, easy to work with and readily available. 3/8 are the ones I've used, but any size will help strengthen your box.
I only use one layer of mat to make the initial shape. Then I switch to fiberglass cloth for adding layers inside . Cloth is way stronger than mat. Mat for the form, because it forms in really well, and it's good for the top layer for a smooth finish. But cloth (weaved fiberglass) is where the stregth is at.
You can also add ribbing using free paint sticks they are good bracing basically free when you buy paint “to pain the box” and they are flatish so easy to glass over
you can also use styrodure to add thickness. just cut it into strips of desired dimensions and put them so that the fiberglass mat spirals around them. For example you start by making a base layer of fiberglass mat and then put on a styrodure strip and laminate over it. Then you take another styrodure strip and laminate under it etc. For making custom shapes you can do those with modelling clay and when the clay surface gets semi-dry you paint it with at least 5 coats of plastidip so the moisture doesn't escape the clay and makes it crack. For better release of the fiberglass from the plastidip you can spray it with 4 coats of pva. I reccomend you do 3 layers with fiberglass cloth or maybe even carbon fiber and epoxy resin. Epoxy doesn't warp much and the smoother surface you get with cloth or carbon will spare you some sanding. You can then add layers from the inside for strength because the epoxy resin won't warp your creation.I might be doing a subwoofer enclosure soon and if i do, i'll make a video.Hope this helps or gives new ideas.Cheers ;)
What I have done is laid down two layers then added 1x2 strips of wood making a grid and 2 x 2 strips for corners and brace points then layered 2 - 3 more layers of 1.5 chop mat.
you can also make something like an X shaped template, put it where you know you'll have a large flat spot, then mask all over the area. this way when your fiberglass is hardened and you take it all out, you can keep your template and the bends are permanent in the fiberglass. :-)
i have made a subwoofer box in the spere tire well, and i used foam to make a small indetation in the bottom to add stifness, the foam also soaks up the resin, makingingit eaven stiffer.
One important detail to keep in mind, if you are laying up one layer then letting it cure before adding more you run a major risk of delamination, separation of the layers. Resin alone has very poor mechanical bonding qualities.
Hey mark I bought 2dual15 boxes from attrend they are nice BUT I KNOW they not gonna hold up so I'm reinforcing them don't have time to build before slamology so I'm gonna glass the inside of the box and I put 50fastners in each box and extra wood trim your though ts
Just made a contoured enclosure for my bronco. Wood bottom with a cut out and a fiberglass tub going through it. I cant imagine anyone would want to screw the fiberglass part of their enclosure to the wood part. The ester resin bonds it plenty well, right?
Very helpful videos, I'm in the process of building a ported dual 15" fiberglass subwoofer in place of the rear seats of my 1987 IROC-Z, I have the mdf built up for the base and bracketing for the subwoofers themselves. I'll be pumping out approx 10,000 watts from the subwoofers, how many layers of 1.5 oz fiberglass mat and fiberglass cloth should I use to make sure it doesn't blow out when I turn my sound system up? Thanks
Good night. I love your channel, congratulations on this great program. I have some questions. I have a 2016 GMC Yukon and I really do not have space in the rear, it is very short and I saw in a video an adaptation with fiberglass, they put a subwoofer drawer in each window, this is functional, will not the glass break? I ask you and I hope you can answer me since I am about to do something similar I already have the material to do it.
I'm a Fiberglass Man, make sure you have Acetone to clean hands and brushes, and, He's right, wood is the best to use, it may delaminate from other things, but it'll stick to wood. By the way, 4 layers of 1.5 oz mat, is perfect. I'm ony box now, and it's stiff as ...... We'll, it's stiff!! Good luck, and, make sure to not over "kick" your resin, and dry up extra wet spots!! Let's get it!!
Great video, I have1 question, after using fiberglass matt, can you use Bondo glass to strengthen the Box? (By laying some on the inside or outside of the fiberglass box)
You are a car audio God my friend, thank you for all of your wisdom!!! Is there some kind of mating that you can add between layers for extra strength ?? I think I was told about something like this a long time ago when I had a fiberglass box built in my truck. Thanks.
Using core materials will increase the strength of a composite structure by a ton, but before you look into that I would look at stronger fiber i.e. a quality S glass
Very Informative, thank you!! I have a component related question, I have a F250 so the current door speaker are 5x7/6x8. I'm going to be swapping them to Components, however I've heard different opinions on using the 6.5's as apposed to the 6x8's. I know the larger the area the more bass, but won't the 6.5's give a more sharper sound?? thanks, Mark!!
Great channel. First time trying this. I just bought a 2019 ram rebel quad cab. I'm gonna build a box under one side of the rear seats with a sundown 10". The sides and top of the box will be in MDF. I'm wanting to do the bottom with fiberglass because of all the waves in the floor. Its roughly a 15"x25" bottom. How much material and resins would you think I would need to buy for that size of a panel? Thanks.
Hey your videos are awesome hopefully I can do this by myself. I got a 99 Eclipse Spyder convertible in the backseat area I want to do two subs and an amp. My question is if it's going to be a custom enclosure what do I put down to put the molding on top of, is it foil? So I can make one big long molding right but what goes underneath of it that's my question.. thanks in advance for your help.
@CarAudioFabrication: If you could only have a sealed wood (MDF or Birch) or a fiberglass enclosure for a purely SQ system, would you pick one over the other and why or why not?
hey what's going on man I have a question for fiberglass boxes. I want to build a fiberglass box in the rear floor of my 2005 Chrysler town and country. I'm looking to make the front baffles to be flush with the floor that way I can still haul things in my van. I'm going to make sure I have protection grills for my sub. I'm curious what is the best way to start the mdf perimeter ring or baffle board and to make sure there is the best adhesion from fiberglass to mdf. I just am having a hard time coming up with a way to make the ring flush with the floor and how I will make sure the fiberglass connects to the mdf ring secure and the woofer baffles then can be glued and screwed to the ring. thank you
Hi Mark,I just did my first fiberglass box in the spare tire well.Only the bottom and half of 2 sides are glassed to the sheet metal and there is a lot of curvature.I did 3 layers of 1.5 oz chop strand mat.The area is only 13 inches deep as well.Should this be strong enough or can I strengthen it with some type of epoxy?
hey mark what are your thoughts on heavy weight matting like 26 or 28 oz mat. also the box design you i got from you is still sounding great thanks again
Just tape something to the area you're glassing into an X or you can do lines and then lay your glass over that. No need to embed anything in the enclosure, and if you blend the shape it makes it easy to glass over.
hey mark!! GREAT VIDS!! what do you know about capasitors on factory amps (IE Acura TL) long story but ive lost my center and sub from my factory amp. Let me know THX!! AGAIN GREAT INFO HERE!
Love your vídeos man, subscriber here o/ And i have a project i need the courage to do I have a big trunk and two nice 12"s that need about 40 liters each and long curved ducts to sound nice, plus the amps, crossovers and two extra batteries... The only way i see it all possible in the trunk is with fiberglass to make use of every last cubic inch... Is that the way to go really? Or is there some other option im missing?
Have you built any boxes for a super duty 2015? I want to run 2 kicker l7 solobarics 8". There's only 4.5 inches under the seat, I was thinking fiberglassing the area and towards the front make it taller to fit the subs. Do you have any advice?
Hi Mark my name is Mark Jackson of Bigg Boyz Concepts is been 5 year in the making got a small shop looking to put some of the tools you use in the shop is there a link to were I can order them thanks and I love the videos you put up thank you
What about fiberglassing in cold weather? I live in Wisconsin and am in college so I have a month off of school in the winter, can I glass during my break or is that a no no? Thanks and love your videos, always innovating!
+elice05 oh, cool. i plan on using SMD sunflash so wouldn't really have to worry about that but is that the only aspect that the cold affects? other than me freezing my ass off? lol
First, great video! When I've made fiberglass boxes in the past I usually start with a a wood backing and fleece stretched over a form (e.g., speaker mounting rings spaced out on dowels). How do you calculate the structural value of fleece resined on both sides as compared to 1.5 oz chopped matt? Thx!
Fleece adds essentially zero strength, you are just using it to capture your shape and then should be applying fiberglass mat on top of that. I try to avoid fleece when I can because it just sucks up a lot of resin for no real strength add. Better to use grill fabric to get shape then add glass to shape it.
I have a question. Back in 2007 I had a shop build me a box for 2 15" L7s kickers and it was 9 cu.ft. excluding the port and subs displacement that was going into my 04 grand marquis but the box would sound terrible when the trunk was open so I went back and asked them why that was and they said that the way they built the box was so that when the trunk was closed there would be a very small space left in the trunk and that would counter act with the pressure that the subs would not deliver so it was kinda of like an infinite baffle inside a box. Never have I seen such thing. But my question is 1. If my box is less cu.ft. than my subs require can I just make a bigger port to make up for the missing cu.ft.? Basically the opposite of what they did?
Your correct, and honestly I don't remember resin being that expensive so I really don't know what the #&$^ is going on here within 2022 because I bought 2 clothe bags and 1 small can of resin and seemed way to much money considering the other products haven't increased in price
in my day, I used to get hessian rope and let it soak in resin. Then laid out a nice waffle pattern with the doped rope. Once the rope has set, and more layers of matt.
+pszresonation well he did have a lot to say with answering everyones questions. not standing up for the guy but it was a pretty long vid of just talking and can u forget what I have to say at times.
hi I wanna build a competition scoop box for my single 15" mmats juggernaut can u plz help me with the spec I modify the voice coil an put 4 competition spiders im using a 7 k stetsum mono block but it still not performing
Hi, I like to watch ur videos & been able to make all sorts of things depending on Wai see on here. Now I'm a visual learner if I see in the process of being done I can mimic wat i see but as a design aspect not very good, meaning if I tell u what I have & u give me the measurements of it or a drawing with the measurements I able to, now I'm on here looking for a tuned 35 to 40hz sub box for 0ne 10" pioneer subwoofer to put in my 03 suburban I'm going all pioneer system here & also I use my suv cargo & need a subbox easy to take out by myself can u help me please reply tnks in advance
Hey man, I got a question for you actually... I got a SWA-10S4 10" SCV Bassline Alpine subwoofer 4 ohms and I bought it as a package from car toys that came with a Bassworx sw10b 10" sealed 0.54cf enclosure. It literately sounded like shit nor did it bump at all. I grew on ported boxes with old school alpine brands;so I'm raised and familiar with that shit, bumping on old rap like Ice Cube and Tech N9ne (NO NOT THAT NEW SHIT.). I want that type loud and bumping down the street type of sound; so I picked up a 10" Atrend Bbox E10SV single vented box that is Gross Cu. Ft. 1.25 \ Net Cu. Ft. .90 \ (Tuning 39Hz) \Speaker hole cutout 9.12" on Amazon.com. Do you think I should use polyfil in this? I just want my shit to bump without that bullshit or damaging my subwoofer. Oh, Most importantly. My amplifier is a MRV-M250. PLEASE help my dude. I've spent so many countless hours trying to get my shit right and to make it hella lit.
Took me twenty years to "just try" building a fiberglass box. Learned a ton, gained some experience and now I have a fiberglass box.
Hell yeah!
This is the comment everyone needs. 🙏
That's my motivation for looking into it. Gonna "just try" my hand at it. Worst case scenario I can't ever figure it out. Best case I get a box.
I made a curved box about 15 years ago, that thing has been rock solid since, amazing how much strength there is in the process.

You can also add ribbing using free paint sticks they are good bracing basically free when you buy paint “to pain the box” and they are flatish so easy to glass over
Cardboard tube going across the box, then cover the tube in fiberglass & spread it on each end, BAM!

i'm a little behind, but i really dig the new logo! this video is a great guide, and i'll definitely be using it.
i have made a subwoofer box in the spere tire well, and i used foam to make a small indetation in the bottom to add stifness, the foam also soaks up the resin, makingingit eaven stiffer.
irockyuorule smart!
One important detail to keep in mind, if you are laying up one layer then letting it cure before adding more you run a major risk of delamination, separation of the layers. Resin alone has very poor mechanical bonding qualities.

Hey Mark, great video. Is it possible for You to use beside Imperial units also metrical? Thanks a lot.
Just tape something to the area you're glassing into an X or you can do lines and then lay your glass over that. No need to embed anything in the enclosure, and if you blend the shape it makes it easy to glass over.
what is the best way to figure out the air space of a fiberglass box that's molded into a trunk corner?

What about fiberglassing in cold weather? I live in Wisconsin and am in college so I have a month off of school in the winter, can I glass during my break or is that a no no? Thanks and love your videos, always innovating!
cold weather is actually better to me when glassing b/c it takes longer to dry, so u can fix an imperfection
+elice05 oh, cool. i plan on using SMD sunflash so wouldn't really have to worry about that but is that the only aspect that the cold affects? other than me freezing my ass off? lol
hahaha! yup
How would you figure cu ft for a full side mold fiber glass mold with just a mdf bottom
Man I want to fiberglass my new door speakers. Is there an easy premixed I can use.
First, great video! When I've made fiberglass boxes in the past I usually start with a a wood backing and fleece stretched over a form (e.g., speaker mounting rings spaced out on dowels). How do you calculate the structural value of fleece resined on both sides as compared to 1.5 oz chopped matt? Thx!
Fleece adds essentially zero strength, you are just using it to capture your shape and then should be applying fiberglass mat on top of that. I try to avoid fleece when I can because it just sucks up a lot of resin for no real strength add. Better to use grill fabric to get shape then add glass to shape it.
Do you now how to built a box for a dodge ram 03 doble c.from fiber glass
It appears that you mostly use polyester resin. Have you ever worked with epoxy? Are there any advantages to one over the other?- BigAl205
I cracked my 13w7 box cutting the hole how to avoid that?
I have a question. Back in 2007 I had a shop build me a box for 2 15" L7s kickers and it was 9 cu.ft. excluding the port and subs displacement that was going into my 04 grand marquis but the box would sound terrible when the trunk was open so I went back and asked them why that was and they said that the way they built the box was so that when the trunk was closed there would be a very small space left in the trunk and that would counter act with the pressure that the subs would not deliver so it was kinda of like an infinite baffle inside a box. Never have I seen such thing. But my question is 1. If my box is less cu.ft. than my subs require can I just make a bigger port to make up for the missing cu.ft.? Basically the opposite of what they did?
I see I missed out something the box was extremely loud when trunk was closed🙂
how do u connect a 4 channel amp to aftermarket speakers and radio
Your correct, and honestly I don't remember resin being that expensive so I really don't know what the #&$^ is going on here within 2022 because I bought 2 clothe bags and 1 small can of resin and seemed way to much money considering the other products haven't increased in price
If it dries out and needed more layer, can I just add layer on it or do I have to do something else more to make sure the new layer will stick?
Depends on the resin. If the resin waxes between layers you have to sand
about to make a box. wondering if there is a sound quality difference between MDF or Fiberglass sub box for non ported 12"s.
Nope
in my day, I used to get hessian rope and let it soak in resin. Then laid out a nice waffle pattern with the doped rope. Once the rope has set, and more layers of matt.
How do i get a box done by you for 1500 ram truck crew cab st
5:58.... so true!
You could actually use foam or plastic for this to reduce weight.
Great vid but who are you looking at? Give us some eye contact bro!

Hey man, I got a question for you actually... I got a SWA-10S4 10" SCV Bassline Alpine subwoofer 4 ohms and I bought it as a package from car toys that came with a Bassworx sw10b 10" sealed 0.54cf enclosure. It literately sounded like shit nor did it bump at all. I grew on ported boxes with old school alpine brands;so I'm raised and familiar with that shit, bumping on old rap like Ice Cube and Tech N9ne (NO NOT THAT NEW SHIT.). I want that type loud and bumping down the street type of sound; so I picked up a 10" Atrend Bbox E10SV single vented box that is Gross Cu. Ft. 1.25 \ Net Cu. Ft. .90 \ (Tuning 39Hz) \Speaker hole cutout 9.12" on Amazon.com. Do you think I should use polyfil in this? I just want my shit to bump without that bullshit or damaging my subwoofer. Oh, Most importantly. My amplifier is a MRV-M250. PLEASE help my dude. I've spent so many countless hours trying to get my shit right and to make it hella lit.
Hyptonic Promotions .. sounds like you need more amp power or more subwoofers.
