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
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
Lot of harsh comments... some people's children. Tch, tch. Glad I watched the videos. Now I have an idea what I can do with the tools I have. In my case, I hope to build a center console with a woofer box included for my minivan. Thanks for helping me with the basics.
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?
@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.
Another way to trim the carpet is to overlap the seams on the bottom and then cut with a knife leaving a seamless appearance. Also, if you recess the sides slightly by 1/16 to 1/8, you can fold the carpet over the edges and then use a knife again to trim the carpet in to the recess. This eliminates a seam on the edge where it can come loose. Just glue a piece to the sides and trim along the recess to finish.
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
The thing that cuts out perfect holes is called a router... and it has many different functions. These precision tools just save alot of time because you don't have to sand edges on inaccurate cuts. If you really wanted to, you could build this with jig saw and a drill. And all the tools they used happened to be sitting in my garage because my 93 year old grandfather used to be a carpenter, lucky me ;D
These videos are pretty handy. The only concern I have is the seal between the carpet and the woofer. If you were to lay the rim of the woofer directly on the carpet, would that not destroy the air tight seal you have worked so hard to create? No matter how tight your screws are your carpet is going to leave less than air tight connection. You could damage your trim ring if you screw too tight. I also would mention in this video the damage drying silicon caulk can cause to most woofer surrounds.
One thing they didn't mention about the wiring. You should tie a knot in the wire on the inside of the box and when you put the silicon on the hole on the inside, pull the wire from the outside until the knot hits the box. It will help pull the silicon into the hole to give a better seal, and no accidentally yanking the wire off of the speaker, possible doing damage to the terminals.
Hey man I enjoyed the video. It brought up Ideas that I haven't taught about. And for the guy bitching about the Rotary Guide. He can buy a varible on at lowes if he knows how to use a measuring device and read the manual to his sub to find out the cut out dia. Then divide that by half!!!!
No Ryan, what you are referring to is a ported enclosure. It's design is based on the principle of something called a Helmholtz resonator. There are formula's that you can plug the specs of your woofer into, and get the best air space volume and port size to get a significant gain in output. Like mooz28 says below, it's louder, but you lose a bit on sound quality.
You can have sealed or ported enclosures. Sealed give it a more tight, accurate response. Ported is much louder, not as accurate or tight in response. It's personal preference for which design you want.
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.
The box at the end of the video and the one you guys were mounting the sub in are two different boxes, the angle was the back of the box and when you were screwing in the sub the straight was on the back ;-)
@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.)
@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
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.
On final assembly I prefer to pre-drill,run the screws about 80-90% with a drill,then finish/flush them by hand. A little more time consuming but you really get the feel for not stripping the wood as they mention. I don't trust drill clutches.
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.
@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)
@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.
@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.
@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
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!
and let the box dry out completely, i have been told that when the silicon caulking is curing it vents gases that can damage the coils. ( i never had a problem so im not 100% on it)
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.
good vid with only a couple of good points, but with that box u ended up with you may aswell just buy a pre-fab, and save all the time, the point of making of a box is to end up with a better than normal box, and a box that will be custom, if you just wanted a 1cf sealed box that looks crappy you can get them for around £14.99.
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
@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.
@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! =]
@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
How come u didn't use some dapening material on that sealed box? I have a rockford fosgate power hx2 10" rfr 3110 in a ported enclosure 50L tunded at 35 hz and it's killing my car.. every thing shakes on it. Would u recomend a sealed box for my sub speaker? Thx a lot for your speaker building guide
so waht do you do with the sub wire that you cut a hole for? there isnt a terminal? and why do you have the back at an angle? my sub box is angled at the front. please reply
@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...
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.
I ran out of space... °o° I think the Dry time to reduce caulk damage is around 4-5 days. I didn't mean this to be offensive in anyway, I'm just mentioning what I notice. Thank you.
did you stuff it up or something, at 8:27 the sub is clearly positioned on the slanted face of the box, than at 9:20 the sub is now on the flat face of the box :S, i don't get it, if you make altercations to your plans you should list it
thank you for making this video. i noticed that RF has a new sub woofer out there on the market. the 13" and 16" sub 1ohm. i was wondering if there is a way to run a single 13" 1ohm sub with a 300 watt 2ohm amp.
@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.
3:15 That's the easy way, but you don't want carpet edges on the corners, because it will easily peel off in the time... And actually you can't do that on rounded edges, otherwise you are ruining what's cool.
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 templates that you guys used to make the whole with the router do you sale that tool. that would so make my job a hell of lot easier then that jigsaw old skool style. LOL
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 =(
Great how to!
If only I had the tools your woodshop has!
Gonna go ahead and try anyway.
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

IM CONFUSED! I thought boxes had to have air holes for the sub to breathe??
Lot of harsh comments... some people's children. Tch, tch.
Glad I watched the videos. Now I have an idea what I can do with the tools I have. In my case, I hope to build a center console with a woofer box included for my minivan. Thanks for helping me with the basics.

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

awesome i need to get some soon too. i hope they don't run out.
if you fill in the hole you drilled for the terminal with silicone it helps.
Nice tutorial, thx guys!
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.
@regainrw no. These types of boxes are called sealed boxes because they don't have a port (that hole you were talking about).

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?"

@xxxxRainingBloodxxx depend on the woofer the other boxs dont have "air vents" they have ports google sub box ports for more info
@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.
@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
So much work, much better to just buy a box but difficult to get it custom.
@ihab1990 Yup because RTTI made a sealed box. What your thinking about is a ported box.
damn thats a nice one!!!
i usually use a drill to get teh screw down 90% then use a hand screw driver to tighten so they dont strip.
Are you talking about the holes that they drilled, ran the wires through, then sealed with silicone on the opposite side of the box at the end???
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!
I do! :)
But I must say I bought it specially for that application
and let the box dry out completely, i have been told that when the silicon caulking is curing it vents gases that can damage the coils. ( i never had a problem so im not 100% on it)
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.
dammm that cool it looks wayy better in HQ clearer

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
Great vids
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
@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.
@HumanityWins You tighten it down with screws to make it as air-tight as possible.
Nice!
@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! =]
You find the carpet at an upholstery dealer. Fabric stores.
@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
Why no damping material inside the box? How are you dampening the standing waves within the box?
@MrSHIFTG Yup. I wanted to see how they were going to secure the box in the trunk.
What happened to that video? Part 4????
you will still be able to see edges there is another video about carpting a box. and that one helps alot more
Installers with a lot of money?
Did any one else want to see it in the car?
Nice pros
How come u didn't use some dapening material on that sealed box? I have a rockford fosgate power hx2 10" rfr 3110 in a ported enclosure 50L tunded at 35 hz and it's killing my car.. every thing shakes on it. Would u recomend a sealed box for my sub speaker? Thx a lot for your speaker building guide
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?
besides looks is there any benefits to putting carpet on it?
how to find box size for a Hatch Back ?
so waht do you do with the sub wire that you cut a hole for? there isnt a terminal? and why do you have the back at an angle? my sub box is angled at the front. please reply
thanks!
@1D1E1M1O1N
you can find them at a remate aka flea market that's the only place I've seen them
@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...
is it super important to make your box the the dimensions the sub requires? any help is appreciated.
@benthedrummer100 No there really isn't, but it does make it look a whole lot better
how do you tune a port could you explain that i thought you just messed with the amp settings ??
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.
I ran out of space... °o°
I think the Dry time to reduce caulk damage is around 4-5 days.
I didn't mean this to be offensive in anyway, I'm just mentioning what I notice. Thank you.
Is that 1 cube before or after displacement?
isnt this box 2 small for this sub? and great video thx
so they just had their speaker wire running right through the side of the box to the sub??
nice tutorial how to make a subwooferbox ... but i dont think there is anyone that have all the tools and stuff you used to make that box at home
did you stuff it up or something, at 8:27 the sub is clearly positioned on the slanted face of the box, than at 9:20 the sub is now on the flat face of the box :S, i don't get it, if you make altercations to your plans you should list it
thank you for making this video. i noticed that RF has a new sub woofer out there on the market. the 13" and 16" sub 1ohm. i was wondering if there is a way to run a single 13" 1ohm sub with a 300 watt 2ohm amp.
i love how that guy says Measure! haha MAYsure hahaha lol
Could do without the weird music but thanks for the vid guys.
and whois better you think ?
Why do I not see any vent holes where air can vent while that things bass is booming?
how long would you suggest to let them dry?
i watched all 3 parts and did not see them put a air hole it?
where do you cute the hole for the air ?
@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.
@HenkAnnieNaald thanks mate =]
@KidsDestroyChiptune ok but i tought that it would break the sub ... no?
@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
My drill is always at full on screw mode!
3:15 That's the easy way, but you don't want carpet edges on the corners, because it will easily peel off in the time... And actually you can't do that on rounded edges, otherwise you are ruining what's cool.
Do you ever need a Phase invader hole? At all? Or that's only for dual subs?
nice job i habe to sayyyyyyyy it
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
yal should make a vid like this one but for two subwoofers. 5*
большое спасибо
the templates that you guys used to make the whole with the router do you sale that tool. that would so make my job a hell of lot easier then that jigsaw old skool style. LOL

how much would it cost for yall to build a custom p2d4 10 box for my 90 camaro ??
