Want BETTER bass? Selecting subwoofer size for a ported box - CarAudioFabrication
Вставка
- Опубліковано 25 лип 2024
- Are you trying to determine which subwoofer you should get for your car or truck? If you are doing a sealed design its easy to determine how much volume you have and what subwoofer to pick, but what if you are doing a ported box? An important consideration is to take a few measurements and determine what air volume you have available before you pick a subwoofer size. Once you know what sub size you need and have an idea on the subwoofer box volume you can proceed with a subwoofer box design and a plan to custom build your own custom enclosure.

Say im going with a 1400 watt system, single 12 inch sub in a ported box. What do you recommend?
So what about a vid explaing picking best subs and enclosures for internal car volume. Id like the cheapest (while still being reliable ) setup to almost have the potential to blow a window in my 2005 pontiac sunfire.
Atm i have 2 jbl 1000s in parallel in a ported box in my trunk hooked to a low wattage amp prob putting out 350 rms and 2 planet audio 12 inch dual 4 ohm coil subs hooked to a boss riot 2400d at 1 ohm in reverse polarity to the jbl's. Found out that thats the best mix that that system could do, but my mom has 2 jl audio w3v3-4 12 inch subs in a ported box running at 200 watts rms total in her toyota celica 2004 and she still has twice as much bass as me
Hey caraudiofabrication I've been watching your videos and I think they are great! I'm now gonna add a more custom touch to my original subwoofer enclosure design.I have 2 15inch ssa audio evils and I plan to build my first custom box for them. I designed an 8.5 cu.ft box. But I'm also going to add a plexiglass window custom trim panels and custom lettering. Your videos have inspired me to take it further!
What city as re you located in I would like to get a box designed by you
This is like my ap algebra 2 class. I try and follow along. Get distracted for like 2 secinds and dont have a clue what is happening the rest of the time.
Exactly,... shit i just got distracted again
I appreciate the fact that there's a few car audio channels that explain things in an intelligent, technical manner that's easy to understand.
I hate when I load a video and it starts out like "y'all no wat it is, dis ya boi lil whoop whoop chek how hard dez fifteenz b slammin yo"
I've never seen a video like that.
haha, i luv ur comment!!

Hey CAF. Can you make a video of better understaning ohms or how to wire to the ohms amp can handle.
Get on Crutchfield. They have diagrams for all your needs.
I cant begin to explain how much you've helped me over the last few months, thanks again for another great educational video. keep it up and great work.
Happy Friday! I hope this video helps you guys with planning and determining how much air space you have to work with. If you need help with your box design I can make one for you here: goo.gl/8RSC93

Hey bro i got a 2014 Ford Fusion ,what size fits better in my trunk?
+CarAudioFabrication Mark 2 8"s or 2 10"s for a quad cab dakota..
+Joe Gotti In the Ford Fusion, they have a huge trunk, so youd be safe with a single 15, 2 12's or 10's. If you arent to worried about loosing space, if you a space conservative, run a single 12 or 10 and call it good man! (Girlfriend has a Fusion I put a 12" P3 Fosgate in there on 600 rms. Great great set up, I recomend it, but there is also other brands! Do some research and pick what best would best suit your budget and music style!)
Excellent man! I try explaining this to every customer/buddy of mine, but no one ever listens!! This is great. I didnt really think of doing an average like you did! Thats awesome!
Some really good points made in this vid. Seems a lot of dudes will just buy subs with no real plan. This is a really easy way of getting an estimation of what airspace there is to actually work with rather than just the overall volume. Good work dude.
+D Torbes This is the point I was trying to make. Thank you!
Your knowledge and Dedication to car audio is inspiring. Thank you for your time to explain this foreign language to us the best you can, your a dope teacher and thank you, you don’t know how much you help me!
As always, great video! This would've definitely came in handy when I was designing my box. Luckily, size wasn't really a problem due to being a HT setup. Keep up the awesome work!
Absolutely agree with getting a smaller size to fit the space better. I had two 10" JBL W7s in my truck and never really liked the sound of them. My friend explained that they were too big for the box I had and build me a box for two 8" Rockford Fosgate subs. The damn things rattled my truck with the amount of low end bass they put out. Couldn't get the 10s to do what the 8s were doing. I learned a lot that day that's for sure.
JBL W7s ?
Those subs are teh beats!
Ricky Buffalo he meant JL W7
With all those precise complicated steps, that bass better be god sent! lol
lol no doubt
School doesn't teach audio fabrication
You didn't even start your sentence with a capital... maybe you should go back to school☺
Calm down man. Hiding behind a keyboard while using the internet to vent your personal frustrations really does nothing for anyone. You had a good point with the geometry proving your point that it is fairly simple for people to figure out and do themselves. But then the rest just makes you look as ignorant as you preach others are being. It's unnecessary and to reiterate, it does not make you sound any more educated. Plus, the rest of us are so damn tired of seeing comments like this. It really ruins any good conversation that is actually taking place here.
+Adam Drake
Well "said", it really does get tiring seeing all the hate that spills from the comment section of UA-cam. I do my best on here to be helpful and honest. Then you get the occasional "troll" that just wants to spit expletives at you. I have been directing those "keyboard warriors" to my Facebook page, letting them know they are more then welcome to "friend" me and we can have an intelligent and civil conversation, via Skype or any other VoIP service. Funny thing is they never respond let alone "man up" and show their true identity.
I need a box for 2x15" What car do I need?
haha

Ford Fiesta.... so you can fiesta your music to everyone 🤣🤣
Lmao

after first 30 seconds i didnt know wtf he was talkin bout
very helpful, getting into fab an loving it. have 3 enclosures under my belt now !
thank you so much for this video. it has helped me a ton! I cant thank you enough
doin great dude! im lovin the boxes and help with my project!!
Fetty Wap can only divide by 1738, not 1728
That was a severely bad joke
+Jeff Anderson 😂
lmfao what??
yeah babay
no that's his eye vision
Hey, heres a question.
i have a frs and since the backseat behind the driver seat is unusuable i was thinking it would look cool to either have a port or a sub face out of the backseat behind me and maybe do a lighting effect or something. but wanted to know if it would be too much trouble to do that please.
All hail the bass Doctor!
Lol
Great info Mark. I'm sure this will help a lot of people choose their sub more carefully. I can't wait to make a new box for my car. Hoping to get a router table so I can use some of your techniques and make it stand out
+Russ Lyman I'm dealing with this now. I worked in car audio for about 6 years and got a great new job that is also in the automotive industry. I'm wondering if i can offset the cost of a nice router by doing side jobs. I should just buy one and make picture frames, they cost a ton lol.
+riothero313 thats great that you get to work with car audio and cars for a living. I'm just doing it in my spare time. I bought a Ok router a while ago and only have done a few things with it. I manly bought it and a circle cutting jig so I could cut speaker rings and make them flush mount.
I would def benefit from having a router table I just need the room. It would either have to stay at my Moms house or wait till we get a house with more room ha
Russ Lyman
Yeah, I went from the car audio side that had all of the top notch fabricating equipment to the mechanical side that has never even seen a table router lol.
what do you recommend about making the port going in to the seat hole
Question for future video: How to tune LOC and what do you suggest as an alternative to a LOC? Changing out a stock navigation unit isn't always an option and sometimes it is easier to run from the factory sub wiring that is already in the trunk. Thank you and keep up the great content!
thanks answered a question I had for awhile about gross and net airspace I trust your knowledge is correct much appreciated
great advice, is a mistake i have seen done, thanks for the advice great videos!!!
i never knew the size went down thank you alot
Awesome video thanks for sharing. Wondering if the shape of the box impacts the audio quality of the woofer? For example, will a wedge shaped box sound different to a square box design as long as the air volume and port sizes are matched to the woofer?
Good vid Mark. I do sorta the same thing. I measure the same way. But to find what I have I just take away 20 percent. And that gives me my air. But, then I have to consider port, sub and brace displacement. Thanks man. Even old dogs learn new tricks. LOL
When it comes to estetics this channel is spot on , very cool
great video for getting people ready for the sub design phase of their build.
Great video, very informative. I'm currently in the design stage of building a (single) 10" sub box for my 2006 Tacoma dble cab. Can't decide whether or not to build a ported or sealed enclosure. Have plenty of room behind the seat for either, just want to do whats best for sound quality.
BILLYBOB 976 got bass?
Excellent video as always! I'm currently working on my A-Pillars and would love to see a video on that. Ima have to go to your website and get one of those shirts so I can represent here in Ar.
Great to see someone willing to share the knowledge
Superb as always. Very pleased with all of the box designs so far.
Great video the magic number had me like this 😲 I had no idea it was reduced by so much.
+Aaron Edwards This is the point I was trying to make. :) Now of course you could always get rid of bracing, or reduce the port size and get a little bit more air volume... but then your box may not be as sturdy and may have port air noise issues. It's all a balancing act, hopefully the guideline in the video can help with having a better idea of a true starting point for the airspace so folks can make a good subwoofer decision. Thanks for watching!
Have you got a video on understanding what ports actually do to the tuning of a subwoofer and how to make sure you are tuning into a range of frequencies for your application?
Love the videos. You do great work. I was wondering if you could help me with a design for a chevy tahoe, but the only problem is that I want to keep my 3rd row seat so limited space. Any suggestions?
Hey Mark thank you for the video because I am planning a build in my car and this helps a lot in planning for subs size, size of a box and also considering the space I have to work with in the trunk of my car.
I have a question for you in regards to the car’s electrical system. I have a total of 4000 watts of equipments I need to in stall, my car comes stocked with an alternator that is a 110 amps and a stock batter that is 750 CCA. First question is; 1. Is this enough for the amount of watts I indicated? 2. If it’s not can you give a break down on how to go about upgrading the electrical?
GJ bro ! good info for beginers that knows "alot" ;)
I'm going to measure my new ride as soon as it arrives and email this genius
Bro. You’re are smart. Thanks for sharing your knowledge.
Make a video on wiring subs to amps, to understand ohms
LOVE it
Thanks to your videos, people don't have to ask stupid fuckin questions anymore.
Good day, I have a question for you......the calculations that you came up can that applied to a diy home theatre system build?
+Girvan Malcolm I would think Yes, Its a calculation of average amount of MDF used in "X" space.
I would say if you use 3/4" MDF the calculator would still work.
The Tuning Fq on a Home Theater system and Power will be a bit different, but over all Math still works.
AVS Forums has great info for Home Theater design, you could still use Mark's website to get a solid design.
that magic # .55 does help out , thanks
thanks for the vid
Great vid
Just found this channel. Excellent content, great presentation and knowledge that even the 'noobs' can understand!
I love all types of music. I like my sealed boxes but Ive thrown my subs in ported. I cant find the best tuning number to keep a good kick awhile simply switching tracks and enjoy some massive boom.
28 Hz will give you maximum sound quality just make sure the sub has an FS or 32Hz or lower.
35hz
You want 35hz to 38hz
Hello sir...need a box measurements for single vibe black air 12d2
And for dual black air 12d2's
what do you recommend for 215 Rockford Fosgate T2 inside a 2003 Chevy Monte Carlos SS
moar powar!
Great videos man. Definitely subscribed!
I have a 350z and am gonna put subs under the rear strut bar. Its a pretty small 2 door coupe but i have about 3-4 cu. ft. to work with, what do u suggest?
I made this mistake! I had a 12" Sony Xplod P5 in a 2.5 cu ft L-ported box tuned to 30Hz (which I originally thought was 3.0 cu ft as I didn't realise how much volume the port took up) and it slammed lows hard. I already had to cut the hole bigger because the previous owner had a JL Audio 12w7 in it. I then cut the hole even bigger and put a 15" Xplod P5 in it. It was louder at higher bass frequencies but the lows went to shit. Was using a Soundstream XTA480.2 bridged on both. Now I have a 15" to 10" reducer in it with a 10" Alpine Type R off an LW Audio 1.1600 and it sounds better than ever!
Uhh... I have a logitech
Which Logitech?
RWL2012
You could have spaced the subwoofer out with an adaptor ring to regain some box volume and or inverted the subwoofer
Great information thanks for sharing.
Great vid. Thank you for good tutorials. I have a question, which came up with my current project. I'm building a sub box for two RE Audio SRX 12D4. I want to build sloped box - will better fit my trunk. So upper depth is 10 inches, lower 16 inches. WinISD tells me, that i need vent lenght 17 inches - what I need to do to "turn" port in sloped box - if I do "simple" 90 degrees turn it will collide with speaker magnet. Any sugestions?
awesome vid
Sum 41 - Into Deep in the Background in the beginning ah yeah 😂
What would be the loudest setup I could do with third row Yukon
Downfire, or faces up
I was wanting maybe either 1 nasty 10”
Or 2 8’s
Very helpful thank you

Great video!!!
Was hoping you have an idea for a box for a wrangler unlimited! I'm looking to do a super custom setup
Now the fun begins!!!!
So on your other video you are building an underseat sub box that fires upward, doesn't that impact the acoustic power over having it forward or rear facing?
i have a seal box but it nt that wide
Thanku
thank you
can u tell me what box design would be best for a bmw e36? please.
first off I would like to say thanks for all the great info n tips that are involved in car audio systems.. I have a few questions.
here goes.. I was given a pair of old school cerwin vega stroker 12 both are 4 ohm. but one is svc the other is dvc. my question is would I be able to wire them to the same amp. and if yes how would I go around to doing so.
my other question is the speakers have seen better days.. so with that said I wanna know where I would be able to take them to get recondition or rebuilt. any help with this is very well appreciated and I wanna thank everyone in advance..
Hey I would like to chat about how i can make a nice sound system in my WRX 01 so where should i start?
hello. I just found your channel and the content is very helpful. I will subscribe for sure. I have built a lot of sealed boxes but I have never built a ported one I never was taught why you use them. can you do a video explaining how to size and place one ,or if you have a video already can you point me that way. Thanks for your time, Jeff
Got a fright when he said wrong 😂😂
sir .. how to get the box dimentions according to subwoofer size.. i have two 4.5 inch subwoofers of 30W each
good info thanks man
Excellent information right there. Thanks again for a fantastic guide. Can you talk about mid-range speaker selection sometime? Some of the questions I had were: Do I need to build a box for mids? Do this foam baffles work in place of a box? Should I worry about porting a mid, or build a sealed enclosure? How much power do I need for my mids to work with that new subwoofer so that I have the right balance in sound and not too little or to much bass from the subwoofer? Should I worry about placement and the angle to the listeners ear?
+u9Nails These are some great questions for a future video! Thank you!
Great thx for explaining
thanks vid helped alot
Can you do a show on prefab boxes and how to make them better. Budget vs. no budget?
what kind of box do you recommend for a 20.6 cubic feet of trunk space
Your the king.
What size sub would give me the best output (loud!!) but wouldn't compromise sound quality for an 07 Lincoln MKZ??
Question? What are your thiught on a downfire box for car audio. I know it's has been used mostly for crew cab trucks. Im wanting something a lil bit more unique for a box.
5:00 i wanna see enclosure #25!! WoW! 22ft³
and could I mess it up by going to big on the wall or box
What change if put a closed box subwoofer in a reflex box?
Could you please get it working and find top and sides of amp that's been forgotten
very knowledgeable thanks
32 inch car subwoofers are legendary and only 1 subwoofer of this size was manufactured by a few companies and only be purchased through the manufacturer and can run you up to a million dollars and some 32 inch car subwoofers are not available to customers and are for display purposes only like the clarion 32 inch car subwoofer which is in a museum currently and was never available to customers to purchase
I would like for u to cover wrapping door panels and dash boards. I wanna do mine in ultra suede with the stitching
I got my 15 firing into my deck lid and it still stomps ass lol and it's in a crappy Pyle wood box and a round pipe port but sounds awesome building a new mdf box soon
I really appreciate these videos, as a novice car enthusiast your channel is extremely informative in the car audio section, usully the first channel i look to for guides and how tos.
Excellent vid and very insightful. What are your thoughts on sealed subwoofer boxes. Do you have a magic number to calculate airspace? Keep the vids coming very cool.
Great video Mark! How does this work with sealed boxes and "slim" subs such as the JL Audio 13tw5v2?
Thanks
