Really interesting to see a different type of built other than a fiberglass or layered MDF box. Thank you for your time in making it for us.

[@24cimbo]

Amazing work as always!I am ill and still in bed so now just watching your videos to get some ideas.Thank you for all the help and effort you put into these videos!!

[@performingspecs7841]

I think it is a pretty impressive enclosure. I was really intrigued with the build process, seems to take a lot of skill and patience.

[@MikeyB00o]

Thanx for making another video Peter. Keep up the great work

[@davef.566]

dude you are awesome thanks a million for showing this technical speaker build :-)

[@charleshamilton6177]

Man your work is impeccable.

[@pssound9749]

Thank you! 🙏

[@XXX-ed2tl]

“It’s nothing fancy.” 😂😂

[@georgekolotouros548]

I'm afraid to ask what Peter considers fancy.

[@brendangood1812]

Thanks for the video Peter. Really interesting seeing your puzzle way, after so many years of seeing moulded fibreglass enclosures, and having done a couple myself. To me this puzzle process has everything going for it. So much cheaper, even strength all around , way less mess and I would say a more fun build :)

[@pssound9749]

Yeah, i hate resin and gloves! 😃 If there’s a really complex shape like with a front glovebox sub install, then yeah, i use FG, but this works for me better now. After you practice it, it’s quicker too!

[@DA33MONEYBALL]

Looks really good.

[@uptobatentertainment]

A lot of work for that little box ☑️🔥💪 awesome vid!

[@pssound9749]

Up To Bat Entertainment It would have taken longer and more painful to do it from resin & fibreglass properly. It took 2,5 days this way.

[@uptobatentertainment]

You do awesome work Peter, thanks for the vids!

[@robbisson6506]

Top notch work as always!

makes it look simple but this is really advanced fabrication.

[@ranvijaydhami7246]

Good work bro

[@abrahamcale3659]

I would really like to see you do the final fill to the boot sometime. Just to get an idea of how it works. Great content. I am looking forward to building systems for my vintage VWs.

[@pssound9749]

Go to playlists on the channel and check out the fabrication tricks and tips. There are many videos and i’m sure some of them show that too. 👍

Just got a skar vxf 15 with similar specs as the helix so far im in love

[@playboy.d472]

I love your work 💯

[@pssound9749]

Thank you!

[@gregorywallace2108]

You could mix saw dust with wood glue to fill the cracks thats the poor man option, lol , it work really well too. But I love your box

[@magalimoreno2084]

Wow... you are one crafty mate with the wood! Haven´t you thought of making moulds on thick fiberglass or carbon fiber with a comercial purpose? I mean... since you´ve put yourself under all of that hard work... maybe you could start manufacturing even if it´s just for your company the thing already done (say 3D printed...) for each and every car you´d happen to have it available... Congrats once again anyways. Saluts!

[@craigbarrett2278]

A man after my own heart. 😊 Don't follow the crowd!😂

[@Marchah]

Nice work there, going to attempt this in my S8 in a few weeks... the B&O sub really sucks. I'll be using fiberglass though.

[@pssound9749]

FG gives a bit more airspace for sure.

[@hmero.silvasilva3739]

Ficou muito bom

[@PacmanBasshead]

I didn't know you listened to metal too! PLEASE demo me some metal one day!!

[@pssound9749]

I’ll share my demo playlists in videos with description next week, that’ll have some metal madness! 😉😎🔊🔊

[@anthonyjohnlemoine]

I have watched a number of your videos and noticed your puzzle technique. Have you tried kerfing the wood to get bends like you need? It would keep the enclosure a solid piece of wood, but allow you flexibility in construction. Just an idea. I am not sure of the tools you have access to. I really enjoy your videos. I have not seen a lot of sound quality construction videos on youtube outside of your channel.

[@pssound9749]

anthony john lemoine kerfing is cool where it can be done, but in this case that would help. The kerf would need fibrefiller over it too to make it rigid, but by then i just join a corner in a regular way and be done with it way quicker. Yeah i know, SQ is hard! If it was easy, everyone would be sharing videos about it, right?

[@Trapperjohn1000]

I have the same car and trying to figure out the way to tap into the factory system. Nice video nice technique

[@pssound9749]

Trapperjohn1000 you’ll need a MOST25 box.

[@Trapperjohn1000]

Pssound I just got it a few weeks ago. Helix is pricy 😬

[@pssound9749]

Trapperjohn1000 many things are pricey in this game! A8 is not a simple platform for audio upgrades either! Check out the latest video of this car install, i shared it last week! 👌

How can you calculate the peak (hz) of a sealed box trying to calculate a 4th order bandpass as c-pilar box for 2 x 15 (GZHW 15-xspl d1)

[@DaCracky]

Just use WINISD and don't forget to simulate the in car environmen

[@cantugbenli]

Hello I own Helix Q10 Woofer. I want to use it in a closed box. How many liters should the box be?

[@mikebonello7494]

i'd consider using CAD to drawer it out and you can calculate all your wood cut angles - no need for filler etc... Looks very nice though!

[@pssound9749]

Draw it out in 3D when you have a moulded shape? Good luck with that when the customer wants the car back quick! 😃

[@motorax.service.motociclete]

Hi Peter, can you tell if it's a bad bad idea to build a custom sub enclosure like that for a sedan (passat b5.5) and not an expensive sub, some entry level around 100euros, BUT without DSP tuning? just power and crossed by the amp? Thanks

[@pssound9749]

Any sub is better than none. Just play with polarity and make sure the sub adds to the midbass and not cancelling out.

[@motorax.service.motociclete]

@@pssound9749 haha. Thanks. The last couple of days i was just researching about in phase/out if phase thing setting because it.s not always a right/wrong setup and it depends of the system, environment etc

[@terrenzojones4560]

Is the box stuffed with foam to trick the woofer into responding louder as though the box is bigger than it actually is?

[@pssound9749]

Terrenzo Yes, it’s stuffed heavily to drop the F3 of the response.

[@terrenzojones4560]

@@pssound9749 Excellent!!!

[@kitchenrenovations8284]

CAD mate, trust me. It’s like using REW - first time takes you forever but once you have it you can get that job done in 12 hours with no resorting to fiberglass, no filling with water to check Volume, etc. The finished job Is very tidy though.

[@pssound9749]

Cool, i’m looking forward to seeing you making it! 😉

[@alexgunner1882]

How do you take measurements for cad?

[@Jesusprayerwarriorbw]

@Pssound Great job on the enclosure! I have a ATS-V sedan and I travel a bit. This will be my next addition. My 2 12's take up about half of the trunk and sadly, I must go to this setup. Can you give me an approximate cost for building this if I have a pro like you do this? If not no worries. I'm in California. So yeah. Cant hire you unfortunately.

[@pssound9749]

Boywonderr71 Hi, yeah, i’m sure it would be cheaper over here than in California! 😃 It was 3.5days labour with the amp install and material cost on top. You gotta ask shops over there I’m afraid. 🤷🏻‍♂️

[@Jesusprayerwarriorbw]

@@pssound9749 thanks for the reply. You do great work. I'll check around and see what shops have good reviews. The again.

At 9:10 Peter the enclosure was for bass ( sound ) not Bass the fish...lol

[@Levi081]

Will definitely be giving this type of enclosure a go in my car, the bose sub definitely has to go..

[@pssound9749]

Jeff3 probably anything is better than Bose! 😃

[@ssalblowy]

Hi peter, quick question when your building an enclosure do calculate the volume that the speaker will take inside of it

[@pssound9749]

Hi, The displacement of the subwoofer is rather important when you design a ported box, in which case the volume of the box has to be measured exactly, because that determines the tuning frequency. When you build something custom like this, you can only estimate the size and hope for the best that it will be big enough for the requirements. Better speaker manufacturers list the sub's displacement too.

[@ssalblowy]

thanks, that really helped

[@i_kill_for_zardoz]

If you wanted to get crazy, you could get a rough estimate beforehand by pressing/scraping foam or clay into the cavity in the car, and then dipping it in water in a bucket. Checking the rise in displacement and doing some simple math will show you the raw volume ( before subtracting the enclosure)

[@theejoeylee]

You calculate FIRST then choose a woofer based on that. Or build the enclosure first and glass the WHOLE inside....then u can fill with water to calculate the volume. Or use packing peanuts and dump them into a 12" x 12"x 12" box. 1 box = 1 cu ft. If the volume is a touch too small for the woofer you Want...use 1 Lb. Polyester filling per cubic ft. This has the acoustic effect of a slightly larger enclosure. Hope this helps.

[@fixitrod4969]

What fiber file and what is "milkshake"?

[@pssound9749]

Fibrefill is fibreglass enforced filler, like P40 / bondo. Search for “milkshake Pssound” and you can find a short video for that.

[@BassHead2020]

I’m assuming these enclosures aren’t tuned properly

[@resulozturk28]

Is helix q10w good for sql? How is tone and violance

[@pssound9749]

Resul It can go louder than most SQ 10” subs in sealed, but after all it’s a 10”. If you want real violance in sealed, then use multiple, 2-3x of them. As per sound: it sounds very nice and very low from such a small sealed box.

[@resulozturk28]

Thanks for answer 👍

Jt the 3rd resin mixed with any additives like sand, wood dust, FG powder, etc.

[@dirtyminerapparel]

You ride? I didn’t know that. I have a 03 ZX12-R. I moved to it after putting over 200k on my 2000 ZX9-R but I only have 16k on my 12 now. It had 300 miles on it when I bought it. It was sitting in a guys garage for years because he dropped it while washing it. I guess after he realized how heavy it was and the cost of repair he just let it sit.

[@dwightstebner2345]

Lost quite a bit of internal volume using the wood.

[@pssound9749]

1-2L, but at least it was rigid this way. I would do it slightly differently now after few years using a puzzle 🧩 technique.

[@georgechaney4585]

Finish product is always impressive. Especially when u first start when it looks like a ugly duckling

Should have gone IB. Straight through the rear shelf or through the rear armrest.

tell the previous installer who had different plans and i had to work around his work! :D

[@UpsideDownFork]

@@pssound9749 nothing worse than that! From the looks of your videos you always make the best of every install! Keep up the great work!

[@PhuckenTacoz]

Explain to me how this is easier then fiberglass? Its cheaper yes but not easier

[@pssound9749]

B_12 the problem is that most fibreglass box builder “experts” think that a few mm thin FG mould is enough to make a box structurally solid too, but it’s not! To the time you build up the layers and the thickness too, that is not a joyful ride! If you like to work with resin in gloves and respirator, then go for it, but i’d pick this technique anytime over FG when possible. Horses for corses, right? 🤷🏻‍♂️
