Custom Perfect Fit Fiberglass Subwoofer Enclosure Box Build

[@ericoxford7069]

Thanks for the video! I'm 36 and have wanted to learn how to do this since I was about 15 . I love a clean looking car stereo system .

[@joshb1434]

As a 15yr old id have had bright colours and neons but as a grown man i prefer a factory oem look i i was impressed with this myself. I learned a lot so my next will be even better

[@pcbassy9404]

It's a long time since I have seen one of this blue wavey speakers 🙂. Nice build!

[@pillcosbyandtheroofies5140]

Great job I like the fact you used notes at the end. The best way to get better. Awesome job!

[@cottonnelson7860]

Nice build. I'm trying to learn as much as I can to custom build 6.5 speaker pods. Thanks for the video. Awesome job as well. 👍🏼👍🏼

[@douglasborowski5819]

This looks factory once you were done!! Great job!!

[@joshb1434]

Thanks, give it a try. Their easy and inexpensive to make

[@pedrorubio950]

My older cousin had two of these subs installed in his accord with a 1000 watt amp ,I believe it was a kenwood & that shit would thump like crazy ! for a sealed enclosure I was amazed .

[@01hondascott]

my buddy had 2 of the silver or grey color ones and he had them on a 1400 watt amp and they also pounded the shit out of his car, at first he had them on a 600 watt amp( first time stereo owner) and thought the subs were crap, he looked at a whole new set up and someone suggested trying a bigger amp first, i swear man just with the new amp it actually sounded like he got all new gear, just a complete difference

[@definingimage]

Nice video. I use spandex, resin and then reinforce with glass mat on the backside. Much easier to work with than wool though

[@andrewjones198]

Yeah their box looks weak. My sub would crack it in 5 min

[@blauerza]

maybe a bit too large woofer vor this space but! i like it thats great thanks for sharing!!!! :):):):)

[@joshb1434]

Enclosure is certainly on the small side but its worked well with impressive quality. Space saving was of greater importance here.

[@antoniotony798]

Good job for a diy keep up the good work, because I'm no professional but I can get the job done. I might have to redo but all and all I did it myself and saved myself some money and it was a learning process💪🏾💪🏾

[@joshuadeacon2283]

Should have also put fiber hair or mat on the outside fleece when you put down your resin to reinforce it more

[@logitech850]

I was thinking about that, will resin over just cloth be strong enough?

[@CoroaEntertainment]

10:17 If that was my box, I would have rounded off the top outer edge of the wood ring, so when the fleece fabric was stretched, it would of had a nicer/smoother transition (no sharp looking edge around the sub). Rounding the top edge also makes it easier to pull the top final layer of fabric smooth (less ripples/bunching up). Anyway, your finished enclosure looks good.

[@gregcy89]

The most beautiful hidden sub box! Its almost invisible there man wow 😱🤩

[@Black973000GTVR4]

Also, mold release should be applied to the tape. End product looks good.

[@titaniumman_22]

Looks killer josh, nice work!

[@joshb1434]

Thanks :)

[@wordtruth6116]

Fantastic video. You inspired me.

[@joestack78]

If that's your first build, pretty good work. You should have glued the ring supports, though. After the resin dried over the wrap, you could have removed them. The glass and wrap is plenty strong enough to hold the speaker. Unless you accounted for it, those supports take up sound volume.

[@joshb1434]

Thanks, its not my first but it was my quickest built. glues doesn't last serious vibration and the supports help hold up when items are flying round the boot space haha

[@adrianhinds9200]

Great video, use a different colour text for the subtitles next time

good work, i'll need one for a 2019 toyota highlander

[@peterthanh226]

how many litters?😬

[@DanB3286]

Only two thing I’d do differently is double or triple up on the fiberglass. Then on the inside use a sound deadener on inside of the box

[@stephenshiels5179]

Good job. Im going to do something similar in my 23 Ranger

[@thorstenwesthowe4858]

Geile Arbeit, mega geworden. Respekt

[@hanskinslo326]

Cool fit and finish.

[@joshb1434]

Thanks, was going for a factory oem kinda look

[@mildtowildrc7343]

Man I have built so many and love it👍Great video and just came across it this morning.Takes the creative mind to custom build and make it your own designs👍❤️

[@symun02]

Nice build. It would be helpful to know how much fibreglass kit to order

[@mikenine110]

Looks nice, how’s it holding up because I didn’t see any fiberglass applied to the outside skin just resin

[@joshb1434]

Still holding up great, the speaker took apretty big hit from a jack rolling around the boot and had to be replaced but the enclosure is fine, i used the remainder or the glass matt i had cut on the inside of the fabric front particularly around the edges and i also wouldnt have the sand the front side smooth

[@johnwooten7775]

Didn't need the info, but I loved the video and your technique. Your next one, try actual MDF board as it will give you denser material for your sub ring.... but not matter, that was damn good work.

[@joshb1434]

Thanks this was built on the cheap, the next one ill build with no expense spared with far greater attention to detail. Mdf is much better to work with. Keep and eye out for my next project. Lots of mdf.

[@jimmckay3841]

Any trouble keeping it in place ? I see it fits snug does it pop out for wieght of woofer and driving over time ?

[@joshb1434]

Never budged, even white driving "enthusiastically"

[@86Kona]

Well done and inspiring video. I just wondered how you fastened the box to the car so tight that it don't move even a car crash accident?

[@86Kona]

Sorry for my bad english. I have to use google translator.

[@joshb1434]

I used lots of velcro, the car that this subwoofer was in has recently been written off in a car crash and the subwoofer didn't budge at all so its more than sufficient

[@86Kona]

@@joshb1434 Good to know. Hopefully no one was hurt in car accident.

[@jamesparker6475]

Finished product looks good. Seems a bit small. A router would have been nice to make the rings but overall it was a good example for most of the at home pros.

[@joshb1434]

Thanks, come summer ill be making more, with fresh iseads and some new tools. Got a project in the process now which everyone should enjoy

[@rtfly193]

VERY nice work.

[@joevanblarcume8469]

Awesome video.. I have a 96 ford ranger I'm gonna have fun with.. Great job. Looks nice

[@joshb1434]

Thanks, there pretty fun to build. You should post your results.

[@adityasaini3235]

Awesome bro . I want to know which type of glu you use to make hard the fiber ?

[@joshb1434]

The same glue i used for the fiberglass, its an epoxy resin

[@Black973000GTVR4]

using a router to cut your rings will be faster and more precise without the need to sand. Also, use mdf and not particle board.

[@alessandropoggi9488]

Really good job and professional finished look

[@joshb1434]

thanks

[@aspri11a]

That looks superb! i was going to build a box from ply but i'll now be trying fibreglass for the first time! Does a fiberglass enclosure sound any different?

[@joshb1434]

No difference from what ive heard myself. Just be generous with the layers and it'll be solid. Fiberglass is easy to work with but use gloves its itchy and sticky

[@mildtowildrc7343]

Love the video but wanted to pass a trick on from an old man!Draw a circle with a framing square🤔After you find center just mark a straight line and put a screw down on the radius of each side.When you put the framing square down it will give you your mark at the 90 degrees and just put the pencil in the middle of it and rotate square keeping against screws!Perfect circle

[@Ev3rM0r3]

I can't wait till home 3d scanners are a thing, the money to be made 3d printing these things is going to be amazing when done. That 3 week build down to a couple of hours will be nice.

[@Marchah]

Exactly this..... i asked for a few quotes for a 3d printed box but it's way too expensive at the moment.

[@majoroverkill1376]

The way I measure air space inside an enclosure like this is to first take a cardboard box and measure out your SQ FT needed for your subs. Draw a line all away around the box where the space you need is. I use wood pellets because there is less air space loss then peanuts and way cheaper to buy. Rice is the best. Fill the box with the pellets and when your mold is done fill it and mark the level and cut to your air space. Set your ring and finish the box, sealed or ported. I hate when they don't show or are guessing the air space needed. Give a sub near perfect air space and it will perform!

[@John_the_baptized]

Doug S fack, I like this idea. I’m half Asian, so rice is easy to access and will be used later. Just put into a clean garbage bag for the measurement. Boom. I think when I get the time to do this, I will

[@jorgepizarro3327]

I actually use homemade playdough and fill up a 1 cubic foot box with that and then I mold into place. With that I get my exact measurements of how big my enclosure is going to be ... Wham-bam thank-you ma'am 😂

[@jessehoward5208]

Really nice job!

[@joshb1434]

Thanks

[@John_the_baptized]

Solid work. Question though, is it wise to reinforce areas that are long and flat due to flex? I plan on making one for a 12W6 and worry about flex

[@John_the_baptized]

What would you recommend for reinforcement?

[@joshb1434]

Add as much fiber glass as you think you need for little to no flex then add another layer to be sure. More glass is less flex and less flex is good

[@danimaljenkins]

Good work! I'm trying to find something similar for my 2017 Honda hrv. No luck yet, and I'm nowhere near as handy.

[@joshb1434]

follow my method and take your time to learn and you will end up with great results

[@unitedcolors2920]

Good job bro 👌👌👍👍

[@exxtrmmst]

Was the black cloth you used after securing the rings in place, wool?

[@joshb1434]

Yes its wool, it will stretch and create smooth curves and absorb epoxy resin really well.

[@j.l.201]

You should post your results on youtube. Theres some great help from knowledgeable people amongst the rest in the comments

[@yongyuthmeemuang]

[@daygoguy1904]

Do you add fiberglass and resin on the inside of the box after you lay the cloth down tight?

[@paulhatch8451]

I want one for my back left cubby in my trunk. Thinking a 10 inch or 8 inch. Just enough to hear it but help reduce high bass on my jbls I'm swapping out in place of Harman kardon blown speakers. Factory is like 320 watts. Just wanted to add 80-130 watts

[@AntoineFinch]

I wish I could do this!

[@todderbst9878]

Pretty impressive work. Your end product looks fantastic. I have the same question as an earlier response- how did you secure the "box" to the vehicle? Thanks!

[@joshb1434]

Just Velcro, the fit is perfect so only needs enough to hold it in place. you can then trash the car round any corner with no worries :)

[@steameblair]

very nice build ,am thinking about building 1for my vw gti mk5

[@joshb1434]

you should have a go, just bare in mind the cold will cause fiberglass to cure very slow, use a heat gun :)

[@evanmoses9437]

How did you factor in or calculate the appropriate volume of airspace required for that particular sub? Great build.

[@joshb1434]

Thanks, I have an eye for size, made an educated guess and aimed for 0.7 to 1.1 cubic foot, most 10 inch subs below 1000w will be fine in a small enclosure. larger would be better but my idea on these subs its to have a good balance of sound and space. The sound is impressive, I may post a video trying to show the quality but listening to speakers through other speakers after being recorded on a phone doesn't translate too well

[@juanjosegonzalezdorta5113]

Felicidades por el trabajo lo único que yo le aria es hacerle un agujero⭕ para que salgan los bajos👍

[@Fall2Caine]

I have so many concerns about this, from the way the fiberglass matting was used to the way it was cured, to the use of corkboard inplace of mdf. The overall product came out amazing looks wise, but i would be extremely cocerned about putting a quality sub in a enclosure built in this manner

[@bankal1442]

hey, what would you have done differently ? about the fiberglass mating especially ? thanks

[@robintodd3901]

I would have made it a hell of a lot thicker and milkshaked the inside of the enclosure to make it dense and solid.

[@Fall2Caine]

@BANKAL if i remember correctly this guy did this with not alot of glass he also chopped the matting when if using sheets of glass like he did here tearing the glass to let the strands bind together is the best way to get proper adhesion, should never use any form of "wood" that isnt proper MDF or Plywood board for an enclosure corkkard being probably the worst option you could use, and the enclousure doesnt have much shape to it helping with ridigidity so ebedding some fiberglass rope strands or wooden Dowling within the fiberglass portion of the box to help reduce the level of deflection and amount of pressure put on the glass to not cave or break under pressure. Ive split the wood on a box that had 2 12s because the mdf was cheaper quality and not as thick as it was supposed to have been, and msf is alot less prone to that issue than fiberglass enclosures are

[@marcosstr]

I have a ford fiesta and I don`t work with fiber glass and I needed the trunk space. So I Built a small, under seat, small sealed box with a 6" sub, it`s amazing how more effective is to have the sub inside the cabin, although I miss the punch of my 12". I really liked the idea of molding but my car don't have this kind of side panel in the trunk, just carpet. So I'd have to do the molding inside the car, maybe I'd give it a try some day. Btw, how many layers did u use? Great job!

[@joshb1434]

I used 3-4 layers on this, i did this out of the car because i had that interior trim piece spare, usually i do them in the car. There quite easy you just need to make a start and keep going till you master each step :)

[@killabee623]

That,s dope yo.

[@joshb1434]

Thanks

[@gabed2782]

How do you keep the enclosure from falling out when the bass hits?

[@rayj4722]

I’d like links to those sick beats, it was educational but I was really into the tunes. What exactly did you use for the mold?

[@joshb1434]

The mold i used was a piece of the cars interior where the sub was going to be fitted, i had that extra piece of the interior laying around so i used that for the sake of the video, ill track down what tunes i used and ill comment where with them. I know there from NoCopyrightSounds
