Building a custom fiberglass subwoofer enclosure & trunk setup in 10 minutes (Time Lapse)!

I decided to make a 10 minute version of my subwoofer enclosure build for those that want to see a start to finish project with out all the talking and filler. The items/equipment used in this video will be linked below and if you want to learn how to build one for yourself check my other videos below.

One of the most thorough sub enclosure build I’ve seen.. Wow! Awesome job. Looks great.

[@Foxcraze]

I appreciate that, I have a 4 video series on the channel that’s goes into even more depth on how to build one yourself from start to finish.

[@sfantuchiroasca914]

you call that thorough?? a boz that light can pass through? no bracing?

[@ekimandersom4478]

Maybe you should watch other video’s then

[@Foxcraze]

@sfantuch what are you complaining about? The enclosure has over 5 layers of glass which is more than sufficient for what it’s required to support. The only surface that isn’t a complex shape and flat is the bottom which is wood so it didn’t require structural bracing. Not to mention it’s been solid with no cracks or issues for several years of use so far. Do you have a video or something you have done to show us what right looks like?

[@jackflashautorepair4323]

I was about to get started on this project for my car and wanted to see how others did it. This couldn’t have been more perfect for that. Same subwoofer location I am wanting, same materials I was looking to use, even the same subwoofer I’m hoping to use. When you whipped out the wood floor it really blew my mind because that’s exactly what I was planning to do as well, so in the future when I have air ride I will already have a nice trunk setup I’ll just need to add the tank and compressor and run the lines. Awesome job!

[@Foxcraze]

I’m glad you found it helpful!! If you want to go back and look at the entire series there is a lot of good tips and tricks in there that will prob help you out! If you have Instagram, sent me photos when you’re finished cause I would love to see it!

[@Unchained1987]

@@Foxcrazequestion when you put the ring on for the subwoofer what was that material for the front before your fiberglassed was that a sheet?

[@Foxcraze]

That was stretch fleece from the craft section of Walmart. I have full length build videos of this entire trunk from start to finish in my video library that gives a lot more detail.

[@cornelionutmicu3640]

Hey @Foxcraze what did you use to.sexure the case to secure it to the trunk?

[@Foxcraze]

@cornelionutmicu3640 so no lie it was so tight in the molding that after adding the wood panels to the floor it locked it in and it hasn’t move an inch.

[@jamesleary1405]

That was a great relaxing video bro. I'm 42 now but all through the mid too late and early 90's and 2000's This is how i made extra money on the side working for myself through mostly just word of mouth. I had a honda accord and took out my back seats and built probably my most crazy setup ever in place of the back seats using basically the same method. That car was crazy loud back in those day's before thing's really blow up in the bass and system world with some of the crazy stuff they got out there these day's. I made good money doing stuff smaller though like you did. My car at that time was the biggest project like this i ever did and it turned out amazing and clean sounding from highs and lows a well balanced combo between treble and bass. It was all flowing nicely it was just a flat surface over that wide area instead it looked like a wave kinda with speaker's from 8's too a 15 being the largest in the middle 8's on the outer then some 10's and the 15 it was so beautiful and i wish i still owned that car. A buddy of mine borrowed it and got into a bad accident and by the time i was allowed too actually Physically see and touch my car the majority of whatever was still good from that massive project of a system was stolen so i was told by the lot it was being kept at while investigation was going on because it was a bad accident unfortunately. But watching this brought back those memories of the amount of time and sweat and everything that went into that build. Thank you for the relaxing video and memories it gave me of a time when this was how i made a living all those year's ago.

[@Foxcraze]

Yeah man I feel everything you’re saying. My old truck had a wall of MA Audio 1200 XL’s running on over 4k watts. I have been dabbling in cars and the such since I graduated high school in 2004 and it’s been a constant learning experience. I will likely keep doing this shit till I can’t anymore, it’s just makes me happy haha thanks for the watch and the positive energy.

I'm watching this a year after your original upload. I've watched your whole custom sub enclosure series and you've done a fantastic job. I'm now going to attempt to build 2 fibreglass speaker enclosures for my Seadoo jetski. Thanks so much for sharing. I've liked all your videos and subscribed.

[@Foxcraze]

That’s awesome to hear! I made this channel to document my projects in an effort to teach anyone something new and to learn from my mistakes. I’m glad it’s working!

[@monokuma__8661]

Amazing build Foxcraze!! I've been wanting to start on a fiberglass enclosure for my two tens!! Almost like your build, but two different fiberglass enclosure's on each side. I will have to see how it would settle, since it might take up a lot more space, rather then doing one side. Still, amazing build!! This will definitely help a lot!

[@Foxcraze]

Awesome, I’m glad to hear it! For a more detailed build of the enclosure I have a 4 part series deeper in the video section that goes into way more detail.

Nice, I just purchased a 94 Mercedes Wagon and cant afford a box in my space if I plan on folding down my seats so this will be a perfect solution. I am sure your new Sub outperforms your factory sub.

[@Foxcraze]

Oh yeah making a custom box for your application will be a great idea! This setup hits way better than the factory setup did, I love it and works just fine for my needs!

[@fofdeejay]

Looking good 👍

[@Foxcraze]

Thank you!

[@Dasbeerboots]

Looks great! I have two of these from OEM Audio+ in my BRZ. The only thing that was puzzling to me was the Dynamat inside the enclosure. It won't let sound leak through the enclosure walls, but it will definitely create standing waves and reverberation. You need to use some polyfill insulation to help with that.

[@Foxcraze]

Good idea, thanks!

I remember in the mid/late 90's where there were big car-audio competitions where skilled people would compete in who made the best sounding system that was hidden or more or less intergrated with the car. Much more interesting than watching someone toss 6 15" woofers into the car and think they got skills.

[@zigwil153]

Agree. Always loved hidden systems. Back in the 90's a friend of mine had a civic hatchback with a 18" in a box that would barely clear the hatch. Didn't care then...

[@GeorgeZaharia]

i got a e46 wagon and on both left and right there are some "doors" for battery and other side not sure what is there but im considering remodeling them to give some space for 2 subwoofers since the left and right side are a bit towards the fenders and have so much space that i can do a "inflated" shape hmmm... i like ur result

[@jacoblewis8198]

This video was just what I needed!! I got a sub from my brother for my birthday a couple days ago and wanted to do this exactly. I was just wondering if i should cut a hole in order to make it ported. Also where do you recommended putting the amp?

[@Foxcraze]

Making a port is purely up to the sub you are running. If you haven’t ever made a box before calculating the port size and all that might be a bit much. If the sub will function in a sealed enclosure I would def consider doing it that way. I recommend mounting the sub under the deck lid to ensure it gets airflow and is out of the way. Amps mounted under the trunk carpet tend to over heat if they aren’t allowed to get cool air or if they don’t have good internal cooling systems pre installed.

[@nemolevola]

Hmm🤔 Still thinking about what kind of subwoofer I want but I will definitely do the wood floor at some point! Good video, shows the making of the box well.

Great work, any tips on how to lay the fiber flat and clean like yours? Last time I attempted it, I had bunch of large bubbles, and my initial base layer was very wavy, not clean like yours.

[@Foxcraze]

It all about percoating the surface with a light coat of resin before applying the chop mat then using the brush to press resin into the mat instead of brushing it into the mat. Pressing releases the air bubbles; brushing won’t.

[@mikes.4811]
