  • hmm so buy $300 + worth of new tools needed to build a box or just buy a preset box for your specific car for barely over $100, that ones gonna be a hard choice....

  • LOL @ 4.09. Thats what she said !

  • That's all you really need for car audio bass is one sub-woofer.

  • At 8:00, I know its so you don't put a hole in the cone, I've made that mistake before.

  • At 5:48, Nice Job Sir.

  • Thanks for showing how to put the carpet on.

  • i dont have one tool that hes used

  • woah. all this trouble getting it air-tight and every woofer leaks air through it sides, no matter how far u drill it in....

  • how long would you suggest to let them dry?

  • funny bunch of know it alls .. I dont think the placment matters in a trunk were it barely fits. Thanks for the video good idea on tapping the board down to get that perfect straight cut on a cross cut

  • not convinced by the carpet job, i hope they didn't charge for it!

  • WTF, the didn't even demonstrate the sound quality of it.

  • i love how that guy says Measure! haha MAYsure hahaha lol

  • this a very good tutorial, however, many of the tools are not available to DIY builders, but there are ways around these problems. Even though spray adhesive may help, MDF is not air tight, and also, depending on the woofers, mounting the box will play an important role in sound.

  • Sealed boxes are shit!!! Ill never buy or make one! Waste of time money and speaker!

  • @jasong2xaccount there better for sound quality noob

  • Thats too much ima just gona buy a made box

  • u fucked my ear at 9:01

  • The box was sized perfectly for that speaker as detailed in the beginning. Each woofer comes with a detailed chart of volume needed for various enclosure types. Also this box is not a "truck" box despite the angled design. When mounting a subwoofer box in the trunk you want to face the speaker towards the trunk and not the seat to optimize speaker performance with the size and volume of the trunk.

    Thanks for the vid. You guys hiring?

  • Don't you think that box is a little small for that speaker???

  • the actual sub is on the wrong side of the box....

    

  • Did any one else want to see it in the car?

  • @MrSHIFTG Yup. I wanted to see how they were going to secure the box in the trunk.

    What happened to that video? Part 4????

  • @benthedrummer100 No there really isn't, but it does make it look a whole lot better

  • besides looks is there any benefits to putting carpet on it?

  • CutCo Super Shears?? LOL

  • i think greg is getting perturbed with jason

  • 8:50

    SINCE WHEN WAS THERE A NUMBER BETWEEN EIGHT AND NINE?!? MY LIFE IS A LIE.

  • thumbs up if u want to destroy that box for being so perfect

  • what material should I use for a circle port? is pvc ok? and why am I getting port noise on my low hz values? are the specs on the p3's for the interior or exterior of the box? I spent nearly 200 dollars on box supplies for my 2 p3's and I'm disappointed to hear this port noise.

  • Comment removed

  • you should have mentioned that the 12ga wire you pulled through should have a knot or a wire stop on the inside of the box so it doesn't get pulled out

  • This is the shittiest DIY series I have ever seen. Who the fuck has preset rotary guides in their tool chest?

  • @plzxillest Presumably people who do this sort of thing every day?

    They mentioned in the previous vid that the preset guides are available on their website. They aren't that complicated though and if you already have a router, you can probably make one really easily yourself.

  • @plzxillest a ton of people do just because you don't doesn't mean it's uncommon I have 2

  • what kind of device that did the holes in the 5:55 minutes

  • I thought having them air tight was a bad thing?

  • @Cr8er1 yeah, pretty sure you need an airhole to prevent the wood from making a bad rattle noise (especially if u have 1 dual sub box, which i think that is what is happening with my current box.)

  • @Axelboii I think you just need to reinforce the box, and/or you could try some poly-fil too, although I've found conflicting opinions on poly-fil or I would post a link. Just search for "subwoofer dampening" or something like that.

    The stuff is so cheap you can try it and make up your mind as to whether you think it works.

    Or do the redneck thing and use unbacked house insulation. ;)

  • @Cr8er1 nope, the air-tighter the better, even if its ported. The boxes job is to completely isolate the front and rear sound waves. The thicker and more air tight the box is, the better it does.

  • no air vent ?

  • @ymalmsteen887 nope, i never got an answer. i have a short bed truck though, so my solution was to make really low profile boxes and just pinched them between the seatback and the end of the cab. they don't have enough room to move anywhere. i hope you can figure something out! =]

  • Two people working - takes so long time, for only one box. Better just order from ebay.

  • Comment removed

  • @Akkuetj A quality system will always have a custom built enclosure for everything, having a custom built enclosure built to the specs the sub is supposed to have will make the system sound 10 times better. It also makes all the difference when trying to have a subwoofer hit low's.

  • can this guy stop moving?

  • no sound test? =(

  • that is one of the worst carpet jobs I have ever seen, that is how a backyard install would carpet, this guy needs retraining

  • What kind of carpet did you use?

  • what would make this video better is if some guy came in at the end of it all yelling "What the hell are you two doing in my shop?"

  • @MontyGarza

    hahaha.

  • mannn lets see it in the car ! ):

  • good pass with the carpet

  • thanks, works great. i actually just watched all these to see how to get the wires inside, lol

  • your not going to put the plastic seal around the speaker

  • Nice!

  • us velcro on the box and put it to the carpet in you car thus keeping it stuck to the floor when you hit you hit a speed bump or mount it

  • :)))))))))))))))))) wow!!!!!

  • большое спасибо

    

  • I think the box looks sharp with just the wood

  • Sexy sub

  • u know in part one i dont remember them calculating in displacement for the sub

  • Don't Subs. usually use and or need bass reflex ports, so all the air doesn't stay inside, which causes better performance for the speaker? Just asking, cause most of the Subs i see, including tiny ass ones(4inches)have reflex ports. o_O

  • @Stanran No, they are ported for more volume, but that port makes the woofer sound more muddied, the sealed box, which is what they're making, makes the volume a little less, but the actual sound is punchier, and more controlled. Then there's bandpass, which combines the two.

  • @Stanran there are 2 tipes of boxes ... are sealed ( small and with out Bass Reflex ports - thouse tipes need a stronger amp.with great Quality :)

    on the other side the one with Bass Reflx ports are bigger , larger in volume and dont need a powerfull amp to give sound, but less quality

  • is it super important to make your box the the dimensions the sub requires? any help is appreciated.

  • @assautlpwnz not super important but u def wanna get it close dont go off by too much

  • Nice tutorial, thx guys!

  • I love the porn music in the background

  • @siemensengineer lol what kind of porn are you watching..

  • how much do you guys charge for a box and installing the system?

  • @KidsDestroyChiptune ok but i tought that it would break the sub ... no?

  • @regainrw no. These types of boxes are called sealed boxes because they don't have a port (that hole you were talking about).

  • where do you cute the hole for the air ?

  • fuckin' nice guys...keep going:-bd

  • legit box build, except you forgot to mention to vacuum out the shavings from the box, that will eat your motor if it gets in there.. lol.

  • @RidinChevySolo I'd hope the people would have the sense to vacuum the shavings from the box lol

  • @phtttt you would be surprised all the homemade boxes ive ran across that still have saw dust in them lol

  • @RidinChevySolo lol thats funny

  • @phtttt yeah its really funny when i pull their subs and just start laughing, they start freaking out, and i tell them i basically just saved their sub from certain death lol. shoot after best buy did an install in my buddies truck, i looked it over, oh man, i saved his truck from certain fire... scary! lol

  • sir jason - pinoy kaba?

  • That was actually extremely helpful, i had no idea how to carpet a box, and i tried it... Needless to say it turned out horrible, but i seem to have done everything wrong, this video showed me the techniques to properly carpet my box :D

  • терминалы забыли установить,ящик для этих динов мал

  • if im building a dual 12inch sealed box and i need 1.25 cu ft for each sub should i make separate compartment for each sub or just make one compartment of 2.5 cu ft for both subs

  • Good vid guys, thanks!

    Somebody get gregg a freakin cough dop already! lol j/k

  • y do u need to keep it airtight if other sub boxes have air vents???

  • @xxxxRainingBloodxxx depend on the woofer the other boxs dont have "air vents" they have ports google sub box ports for more info

  • i like the video.

    i watched al the parts.

    good job!

    (i am from the netherlands)

  • wheres the hole for air to come out

  • @tharshan02

    it's not ported. it's a sealed box, i.e the box is sealed air tight - no air in or out.

  • I subscribed to you guys what a nice set of vids on building a sub box thanks guys.

  • Nightpwner@ I think they drilled the hole, ran the wire through that hole, and silicones the hole on the inside with the wire in it so that no air could escape between the wire and the hole!

  • Great videos, very professional. Didn't understand that part about the wire very well though; he just made a hole in the box to run the wires through silicone tubing?

  • damm they make it sound so easy

  • where do u guys get the carpet???

  • hi can you help me chouse a amp for 2 pioneer TS-W308D4

    will a jbl gto 7001e be ok¿

    plz answe i need ti soon....

  • rub your caulk around the terminal cup lol seriously tho air leaking is not what u want. they got some good tips towards the end. i stripped holes b4 because the drill was on full grip.

  • thanks,great tips it inspired me to make my own box.I had to make a narrower box to fit behind the seat of my Hiace van,so had to allow for movement of the seat.Although I had only basic tools so my job was not perfect but silicone fills the gaps and the rim of the woofer covers my not so perfect hole.Is there any advantage in lining the interior with dacron?I have been told it lessens vibration.

  • I have already built a 3 hole sub box. my problem is the sealing inside of the box is not very good. i need a air tight seal. may i ask what kind of caulking you have placed on this box?

  • Thank you. Great video

  • Nice pros

  • God... Only glue and few nails can't make box strenght! We tested that box and only what can I say is: " it's cheap, bad product! keep away from it! we damaged it dropping it on the floor once!".

    What not cut the hole first? :D

    We make cuts ( speaker carpet ) on the left and right side of box ( it's "invisible" ! ). They use the worst option ( make cuts on the corners! )...

    BTW... My tutaj w Polsce robimy to stokroć lepiej! :)

  • exellent video. you gotta be pretty stupid to do something wrong after seeing that video.

  • Out fucking standing job! I love Rockford they make great stuff.

  • whats the name of the carpet?

  • Someone please tell me how to calculate the volume for custom shaped sub enclosures! I've just been doing boxes as a hobby but now I have people asking me to do custom REALLY weird shaped boxes and trying to tell them which sub would work best in the box volume created. If that makes sense lol. Would be great if there was a device that could figure it out somehow =(

  • @jonwhunt

    you can use anything that is round and the same size like ping pong balls to get a ruff estimate,or air soft bb's to get real accurate. what ever you use make sure it wont compress when you fill the box

  • @jonwhunt Hey man they have calculators online for that kinda stuff :D

  • why do you need carpet ????

  • what about acoustic dampening inside the casing? also i would probably use screws instead of nails for the box assembly. most terminal posts are able to be screwed down and are supplied with a rubber ring seal to prevent air leakage and with a dual voice coil sub its probably worth using a for post one to keep your wiring options open.

  • is that me or they just didnt open a hole to make the air go out when the subwoofer hits?

  • they only said air tight about 100 times.

  • @ihab1990 Yup because RTTI made a sealed box. What your thinking about is a ported box.

  • and whois better you think ?

  • @ihab1990 Depends what you want. A sealed box is evenly loud at each bass frequency (that way its more like a sound quality box).

    A ported box is loud at a certain range of frequencies (and within that range the box is louder than a sealed bxo) and gets less louder when the sound is farther away of that range frequencies. Because of that the ported box is more for SPL (Sound Pressure -> Get loud ;P)

  • @HenkAnnieNaald thanks mate =]

  • so now how do you mount it in a car? dose it just sit in the trunk and move whenever you hit a speed bump too fast?

  • @Tweekin0ut most times yeah lol but ive seen people use bungee cables to secure it um theyve also screwed it to the bottom of the boot which id be scared of piercing the fuel tank

  • @Tweekin0ut go buy some two sided tape / or velcro.....maybe

  • @Tweekin0ut yesh it just sits but it doesn't usually move around

  • @Tweekin0ut nah it doesnt move

  • @MBL0CKG mine move like bitches idk wat u talkin about

  • @Tweekin0ut perhaps if you own a 1000hp car it could move when you floor it, but on a regular car, it doesnt ever

  • @diego571 i am going to have to argue that... the dual 12" bandpass my brother has got airborn a couple times in his blazer... ripped the ground out once...

  • @miniimoto95 he had to be doing something pretty ridiculous to get a dual 12" box to lift in the air that thing has to be at least 25-35 lbs minimum probably closer to 40-50 lbs...off-roading maybe?

  • @Tom64o just over a dip on the street once and offroading a couple times, his ground was a little short so that didn't help

  • @Tweekin0ut

    maybe the weight of the woofer keeps it in place.... Or you can mount it...IDK

  • @quadzilla60 the weight will usually keep it in place sometimes they slide around your trunk but just get velcro strips from home depot and put them under the box...worked for me in every car i've owned.

  • nice job i habe to sayyyyyyyy it

  • this might be a dumb question, but what would happen if you didnt put carpet on the box? like is that just an aesthetic kinda thing? or does it actually do something for the sound?

  • you dont need carpet on it, but it does make it look much better. some people cover them in fake leather/vinyl type stuff, works good too. if your not gonna put any type of material, you will want to seal up the mdf with a high build primer, and paint it. make sure the grain or the pours on mdf is sealed good before you paint it because it will soak up a lot of paint. hope this helps

  • no it dont make a difference with sound

  • its just for looks

  • @sup2192 aesthetic. i just finished my box like 5 minutes ago, and i'm thinking i'll stain it. made mine out of plywood, and i think it'll look dandy. i guess if anything, it'll add a little cushion if you were to bump it into something.

  • shit! nice job, and very nice tools, are proffesional tools!!

  • i've looked EVERYWHERE for that type of carpet, please tell me where i can properly purchase one, not online. most of the audio places told me to go to a regular carpet factory/store, i did and NONE, like wtf? where are they?! please help.

  • @1D1E1M1O1N

    buddy, its just carpet, go to walmart, they have tons of carpet like that for cheap.

  • i thoughtso too bro, trust me i went there and there is none, they told me they use to sell those materials but no more and they suggested to go to a fabric store, so i went to fabricland, and they dont have any either (=.=)

  • @1D1E1M1O1N

    well, i mean, thats not the only type of carpet you can get for a sub box. Try going creative with color carpet.

  • hmm good point, but the color set i have on my car is black on orange... and i already have the orange spray paint, i just need the black carpet, thats where the problem is.. i cant find any

  • You find the carpet at an upholstery dealer. Fabric stores.

  • ive been to all the nearest fabric super stores.. but thank you for your help

  • @1D1E1M1O1N

    you can find them at a remate aka flea market that's the only place I've seen them

  • theres one down my street, ill check it out tomorrow, thanks for your help

  • @1D1E1M1O1N

    tell me how it goes. :)

  • i checked out the flea market but they ran out, however i went to this place near my college and they sell marine stuff and foam fabric, luckily they ordered some for someone that ended up not showing up, he sold a role of the black carpet to me for $10 xD thanks for your help guys!

  • awesome i need to get some soon too. i hope they don't run out.

  • what about a video on how to mount the box in the car?

  • nice job

  • i dont think that will sound so good.

    the box is to small for the subwoofer.

  • @91fisher

    You have right i think

  • A One Question?

    Can i have it?

    Pretty Please? :D

  • u can cut right acrost it ha ha

  • im a fiber glass peson

    thx 4 tha vids!!!

  • Very nice videos, watched all three....Just wish there was videos for the do it yourselfer that dont have a saw with all the settings for every rockford sub already set

  • btw.. how is it air-tight if you install the speaker onto the carpet??

  • rockford subs usually have a thin layer of rubber on the bottom part of the ring around the sub...when u screw it down it compresses the rubber and becomes air tight

  • i think what the carpet is supposed to do is absorb the vibrations that the speaker emits so that it doesnt transfer into the box and outside. Vibrations from a subwoofer are very strong so it can cause alot of things to rattle and shake uncontrollably producing that "one note bass" distortion

  • it more for looks. MDF is a super dense wood so sound from the sub wont get absorbed into the wood and cause unwanted noise.

    check out steve meade forum on google. Best place to learn about car audio

  • the sub has a rubber seal around the outer edge and also the carpet makes the seal even better. If you tighten your sub down good you dont need to worry bout leaking air

  • @HumanityWins if it tighten it down fully, the rubber on the back of the woofer basket tightened down to the carpet will seal it up.

  • @HumanityWins You tighten it down with screws to make it as air-tight as possible.

  • fcuk!

    i just bought a terminal, extra for clean install :(

  • if you fill in the hole you drilled for the terminal with silicone it helps.

  • no damping ? i have this sub in vented box

  • Is that 1 cube before or after displacement?

  • i wanna see a close up of the edges were you cut the carpet. i can never find a good way to cut my edges.

  • you will still be able to see edges there is another video about carpting a box. and that one helps alot more

  • good job man i leaned alot of tips on how to make my new box :D
