How to fiberglass speaker boxes (3 of 3) ( Subwoofer box )

PLEASE LIKE AND SUBSCRIBE! Thumbs up if you want more.
In this video we finally finished the beginners fiberglass box, You see from this series of videos how something can be created from a few shapes and some cloth. This video goes over the body filler stage and then leads up to the final paint.
In the future we will revisit this project to do some paint techniques such as marblizing a box and finishing work with wet sanding.
Keep in mind this box was made as a quick introductory to the channel. We will be showing much more advance fiberglass but we felt the need to take you back to the beginning just like we started. Stick with us and learn the many different variations like moulds and gelcoats ect....

I tried for the first time in 30yrs of bodywork adding just a little fiberglass resin to the mud.. It's spreads so damn sweet!

[@chevcam92]

Any guy who is a friend of harbor freight, is a friend of mine. excellent video by the way

[@nickguitarguy1]

Thanks for the video. I have made a lot of mdf boxes in the past. I also worked in body shop for years so worked with many of these materials, but never made a fiberglass box. I'm about to venture into it just for personal system. Had an odd shape I wanted to make and fiberglass sounds like the ticket. You have inspired me to go ahead and give it a try. Is for a cubby speaker for my prius.

[@q-tangcreations6499]

Thank you for taking the time to show people how to do this. I am trying to keep occupied and stay busy and this ia going to be a hobby of mine. Awesome and simple diy video thanks for being plain Jane and not trying to be a scientist it helps understanding the basics people tend to become intimidated when people go all extra this was simple and straight to the point without all the added drama. Thanks!!

Awesome videos! I've been mulling over how to build an instrument pod for my old sailboat (new ones are insanely expensive) and haven't found a method that would be light, strong, and waterproof, and still get the nice curvy contours that look good. Your method looks like what the doctor ordered. I'll send you a photo if I manage to pull it off. Thanks!

[@Grayback1973]

Thanks for the video series.Very educational and you seem like a very nice guy!

[@RandomAudioGuys]

Thank you very much. I try and the first video series taught me alot about youtube and we are taking the feedback into the new videos coming soon. Really hope you like whats coming and I can say there will be more fiberglass soon.

[@Grayback1973]

In the near future I am going to install a midbass driver in the back section of my front doors.The front section is where the stock 5.25 goes.Without fiberglassing I think I'll mount a piece if ABS to the door frame and build speaker rings on that to where they come right to the back of the door panel.Then just top mount the woofer right to it and install the grill.What do you think of that idea?

[@RandomAudioGuys]

What vehicle is it. And mounting a mid bass driver to ABS would require you use at least 3/16th or thicker ABS.

[@Grayback1973]

Its a 2009 Nissan Sentra.ABS(1/2 inch) would go over back part of service panel so it'd be bolted top and bottom only.The service hole is pretty big and I've got it covered with Dynamat now.Just seems like a lot of weight for the sheet metal to support plus after cutting the hole in the ABS for the driver the ABS would weaken but the mounted MDF ring could strengthen that back up.Other thing is that there's a foam insert on the back of the door panel that would need to be removed and I'm not sure how that would weaken the panel and cause vibrations from the driver.However,the driver will be top mounted right through the door panel to the MDF ring so that would strengthen that. LOL,sorry for the rant but I'm thinking out loud to a guy that does this for a living and can give me some descent feedback.

[@RandomAudioGuys]

Okay so I looked at the door panel on that and see the foam insert on the back of the panel your talking about. Its moulded to the shape of the door while it could serve as some structure to the door I don't see alot of options so with that removed I do not feel you will harm your door panel much if your going to put a speaker in that area. The downside is that is in the area of your seat and where your arse will be sitting so Im not sure if its an idea location as alot of sound gets covered when a person is seated in the vehicle. Looking over that door panel though , without reshaping the entire thing , AKA a new build door panel I believe your in about the only area to add one without adding a fiberglass job overtop the door panel and putting both up toward where the original speaker sits in that door.

[@SteveCarmichael]

Wow, that looks real nice! Do you prefer the air powered sander over electric? Looks like dust gets on everything.

[@RandomAudioGuys]

+Steve Carmichael I was at my friends shop for that. He was showing me 2 of his new sanders and how they blast through body filler. I think it's subjective to how your shop is setup. Since I have an 11 amp squirrel cage fan filter I would prefer this method going through body filler. For wood I'd rather use the electric Bosch with built in filter.

[@theurbanartist775]

Man I would love to have that box for two 10” Skar SDR’s

[@bigpapahades]

SSI hire do you jeeo the resin/ fiberglass from separating fun the wood? Does the resin soak into the wood and create a bond?

[@GnosisMan50]

Great work ....though quite laborious.

[@deegan727]

Yay body filler, I love the whole process! Sarcasm is hard to type, let me clarify. I’d rather roll around in a bed of that fiberglass mat than fill, sand, fill, sand, fill, sand. However it is a necessary process that you have to have patience with, it will determine how good the end result will be.

[@barnes29510]

It does take passion working with it.... After 30yrs doing bodywork; not long ago, saw a trick to make laying out the mud a whole lot easier... Add a little resin (fiberglass) to the filler. It thins it out. On a flat surface, you can thin it to where it will self level.

[@deegan727]

@@barnes29510 I do the same, but with plastic honey for large areas I want thin application on. That method is invaluable when it’s needed.

[@Jason____]

Great videos thanks for taking the time to make these. I just finished a 4 speaker setup about 2 months ago for my RZR and it was my first go-round with fiberglass so I'm about to remake it. It's got 4 6.5" Infinity marine speakers, a 600 watt marine JBL amp, a marine head unit and 2 LED lights for dome lights. I just used a regular fleece blanket and it took a TON of resin to really get it coated. I'm looking to go to a material that doesn't take so much resin and will be a bit easier to work with. Do you have any recommendations?

[@RandomAudioGuys]

Yeah I've used fleece in the past and it will drink your resin and offers not much flex to doing really strong curves and no added strength. I find the close out section in Walmart to be my best friend. The material you see me using in the video if you go back to Part 1 and look was just a close out. I just go through fabrics and stretch them until I find something thin but with great stretch. When I go into the advanced fiberglass projects Ill bring this up again and try to touch the subject for you. This was thrown together and going back to how I use to do it to how I do it now was awkward but it helps if its your first time.

[@Jason____]

+That Stereo Guys Workshop I'm subscribed so I'll definitely keep an eye out for new content and check out what I can find in terms of materials. Thanks again

[@gitlittoo2161]

I got Stanley from walmart. The black one. I beat them things. And they still do the job. I have alot on HF shit. That out does brands they cost 3 times as much. Cost dont mean the end job will be better.. Facts

[@RandomAudioGuys]

Agreed, the work is in the hands of the man not the tools hes using.

[@jmphelps3955]

Man I just subscribed to your channel on the fact u rep Harbor Freight. You have to know what to get there. But no where is in the same stadium as they are in price, amdnthey have stepped up with nicer brands and the same cheaper brands. I got 75% Harbor Freight tools🤘

[@rouseyanglerholics]

so did you end up fibreglassing right into the port or just body filler? when done with MDF would you have to use the same method that you have used here? Also what product of resin and body filler have you \ used

[@RandomAudioGuys]

I used resin to attach it and then just body filled it up to make it look nice over the OSB, you are correct that with MDF the method would have changed slightly, I use a router bit to put a inset on the edge of MDF so my fabric has a final resting place where the cloth and MDF meet. The body filler I use is typically just a lightweight body filler around 20 bucks. The Resin is Solarrez. It is UV activated so the sun sets it up in minutes.

[@rouseyanglerholics]

Thanks alot, Im in AUS so I would say the products are probably different here but i will what I can find. Also Im curious as to how you would do a fibreglasss sub on a door skin on a 2013 Ford Ranger Supercab rear door? theres currently a pocket there and dont know how you would do it? I dont know if I could send you some photos another way?

[@Grayback1973]

I'm going to be doing my first fiberglass enclosure in the spare tire well.Only the bottom will be glassed as sides will be framed in MDF.Will not need a pretty finish,only needs to be strong and sealed.Any tips for me on this?Thanks!

[@RandomAudioGuys]

Yes, apply 2 inch painters or masking tape to the entire area first. I know its your car but always treat it like its a brand new Lexus that belongs to the pickiest of customers. Then mask it in the other direction and apply some type of PVA so you can release your mold once your done. Other then that its a pretty straight forward process.

[@Grayback1973]

Random Audio Guy I hear you about treating the car with care.I manufactured stock amplifier bypass kits for Equinox and Terrains.I'm convinced people would rather hack/cut into their stock wiring than buy a $30 kit like I make that completely eliminates the need to do that.My mind just doesn't think that way. Thanks for the feedback! Any tips on getting rid of air bubbles and how to spot them while spreading the resin on the mat?

[@johnbrevard5966]

Harbor freight and husky etc is good... But when your in a job and need to get in that spot, and need the strength and design of a snap on wrench, You 100% appreciate that money spent....

[@myuzekal552]

Ever think of making fiberglass body parts? Fenders, trunk lids, etc? (Not for function...just for show) that'd be really cool!

[@RandomAudioGuys]

Maybe in a future video. Sounds like it could be a fun project. Thanks for an idea!

Thats what we are here for, not just to build what we want, even this project was requested and I took it back to how I done thing's when I first started so It would be in line with how people would approach it , not so much how I approach them now. Its all about learning from eachother.

[@darrelldoeing2578]

i have a kinda off topic question i recently bought a side by side and the roof radio setups r expensive as hell $3300 4 speakers and a radio so on to my question will this process work on aluminum will the fiberglass stick to it or do i need a special type btw great video bud thanks

[@RandomAudioGuys]

+Darrell Doeing if by stick to it you mean can you work on aluminum then yes but if you mean if it will stick by putting resin to a flat piece of aluminum and Fiberglass then no. You would have to attach it by bolts. If you were to come around the aluminum with cloth so it went ever the edges and had a way to grip like I do the wood in this video than yes it would.

[@kingscorpio5765]

sup man I recently seen your video's on steps to make a fiber glass enclosure,VERY NICE. I want to learn more about doing this as a hobby . watching a lot of youtube video's help but i'm sure you would reccomend classes for the science of it all. any reccomendations? i'm in nyc by the way thanks

So the only thing holding the round mdf subwoofer rings in is the fiberglass on their faces, and they're the only thing holding the subwoofers in place right?

[@RandomAudioGuys]

Yes once you pull the 2x4 out it becomes that strong.

[@zgreen6604]

Random Audio Guy thanks man. I'm making an entirely spherical subwoofer enclosure as my first attempt at this and was trying to work out how I'll get the subwoofer in there sturdy. This seems better than my original plan probably lol. I'll post a video when it's all done to show how/if it works. I'm getting ready to cut the hole for the subwoofer in the ball as we speak

[@Leysner77]

Do you use polyester body filler?

[@kevinc6073]

What if I want to carpet it instead of painting it? Do I still do the bondo step or can i just set on the carpet after the fiberglass step?

[@RandomAudioGuys]

Thats a good question. The answer is yes and no, fiberglass in its raw stage will still show through carpet. You wont have to worry about as much detail with a carpet finish but some basic structure is still needed so it dont look like carpet over a yarn ball.

[@kevinc6073]

Random Audio Guy Awesome, so a little bit of bondo and sand then carpet correct?

[@RandomAudioGuys]

kevski 305 yes that's all there is too it. Make sure you use unbacked carpet.

$390 (8 wrenches) you broke my heart! My uncle is a 40+ year mechanic and will not buy any tool useless it's Snap on or Mac. I bet he has spent $100,000 in tools. An ex girlfriend bought me a Brench Top tool set (Walmart)and I'm still using them! Not saying they are the best but that was 20yrs ago.

[@motostuna956]

nice have you tested it out yet im curious how it sounds

[@RandomAudioGuys]

Yes actually, Ill be doing a future video with this box. The subs movement was good extension pushing it to the Xmax limits but with a really low bass delivery. Imagine a 15 inch subwoofer banging lows but not pushed to its limits, thats how this turned out. As you know Sound pressure does not show well in videos but it can move the mirror of a van. Not the bass killer that it could be if it were setup for that but just overall a really good sound.

[@Dhutto]

The back side of the box where it is just wood, did you just put bondo over it and sand it then paint?

[@RandomAudioGuys]

Yes, Just a skim coat and then you can treat it like a normal paint project.

[@Dhutto]

Random Audio Guy thank you for getting back with me. I’m thinking of making a roof audio top for my can am commander. Thanks for the help

[@mexdrago3009]

Did you put the body filler while the resin was still drying?

[@RandomAudioGuys]

No it is UV resin, it drys in about 3 minutes of sunlight.

[@randomme890]

What kind of filler are you using for this?

[@RandomAudioGuys]

Just a typical lightweight body filler. Some people use bondo because it can be purchased at most any local retailer.

[@TP-yk2cn]

hey great work what size air tank do i need for air sanders? would 20 do it and paint too

[@RandomAudioGuys]

I personally use an 80. and remember it's also about your cfm not just your tank. I started with a 30 gallon that done 6.7 cfm at 45 and 4.8 cfm at 45psi. My current setup is 80 gallon with 18.4 cfm at 90 psi. and not rates at 45. It may be best to start out with a harbor freight 30 gallon unless you plan on making a living than go to a bigger unit with a better motor and tank.

[@TP-yk2cn]

+Random Audio Guy thanks man much love again great work i am a beginner and I plan on doin fiberglass work along with paint cars just learning tho more hands on type of thing

[@RandomAudioGuys]

+kingchevy614 spraying with that small of a tank wouldn't be a good idea. reason is when your spraying when it kicks on it will spurt a splotch of paint when it first starts up the compressor. you'll minimize this the larger the compressor and tank. I'd your gun your spraying with is for example 6.5 cfm then in the real world you want double that. so it's able to fill the tank and supply you with the 6.5 cfm you need at the same time. just a learning process is all.
