Dont spend so much time defending yourself. The box looks damn good for the space you had to work with. Those JBLs are damn good subs in a sealed box. If the coils are good in them dont throw them out.
Don't be ashamed of not know something we all had to learn everything we know at some point nobody's born with the knowledge don't be afraid to admit when you don't know how to do something you learn more that way but don't take crap either no reason for someone to be an asshat.
30-35 hz tune. Youre gonna hate it when you realize you gotta build another box. 60 hz means anything (a ton) below that will drop off and you wont hear it. Its gonna be peaky and very boomy right at 60 hz. Good job on the build tho.
Of course I don't know any of your measurements you still did a great job on the execution on the box but the sub has measurements they call thiele parameters and you use that to find the tuning of the box . . The wrong tuning can possibly ruduce the power handling and sound lever of the sub and turning to 60hz is a little high your lows will be very washed out and quiet . . But depending on the music you listen to it might be perfectly fine . . Great job with the box and trying to do the research but it's a lot to take in at once when you dive in to it like that . . Love the channel man keep up the good work
I think a sealed box filled with polyfill sounds the best. I used to have 2 eclipse aluminum 12’s in a sealed box filled with as much polyfill I could cram into it. It sounded badass!
I think you did a great job building this sub box! I noticed that when you glued the parts that it ran a lot and was messy. If you use a small brush or your finger and spread it you won't have nearly as much clean up later. also I believe it holds better if it's spread evenly. I hope this helps.
Not bad. Personally I would have made it one large chamber with a central port. You get a bit more spl out of it that way. I did about the impossible with my f-150 which has a small and lower seat bench then most trucks, I was able to stuff 2 cuft. underneath with two central 4" round ports via pvc. Ran two Rockford Fosgate P3 v2 shallows in it. I was impressed by how loud it got.
Great looking box if that's your first one ever building man. Glad you rounded all edges because I hate seeing a sharp edge on boxes. I build boxes for a living and like I said if that's your first attempt then be proud of it dude.
hey man, love watching your vids I used to make boxes and i can tell ya when you make a box you have to make it for the sub air space is crucial most subs dont work good with ports and small boxes next time try a sealed box you can get away with much lower air space. great box keep up the good work!!!!
Nice looking box. My gut tells me those other speakers are for sealed boxes so they would naturally sound like crap in a ported box. The kickers are stiff enough to probably work ported or sealed. The will eat more power as a result of stiffness. You could temporarily seal the ports and see if they sound better. Also you should install a little poly fill inside each chamber of the box. Just a fairly thin sheet for noise dampening.
Well he said it sounded like crap. Obviously something is wrong. These books are a suggestion. Orientation and vehicle interior size and shape are everything. Shallow boxes usually sound like crap anyway.
box design comes well before interior vehicle shape, orientation and interior size. box size and tuning frequency play the largest roll in the way it will sound. the engineers for the manufacture did not just pull these numbers from thin air. many calculations and over 20 measurements are made to determine what a driver is capable of producing properly.
Yes, the design of the box was wrong, so it sounded like crap. He should have kept them sealed and they would have done better with a little eq, for both brands of woofers. This is a classic example of how not to design a box, but hey, sometimes it's good to learn by trail and error.
Your construction techniques are on point, material choice is also good. Thanks for sharing your work! If the JBL subs distort, check for clipping input signal from the source, then amp. If your lpf is set correctly & signal isn't clipping it's probably just not the right airspace/design for those subs.
chances are these PRO AUDIO style jbl's don't like being in a ported enclosure and/or they are very sensitive and clip easily which would mean you would need to keep gain really low
Those JBL power series subs were not cheap back in the day when they were new. They're likely close to 20 years old or a bit over. FWIW, JBL was around 40ish years before Kicker. Kicker came out in the '80s, JBL came out in the '40s. As has been pointed out, they may be cooked. If not, you're running them in a box about 1/4 the size they need and tuned at least 20hz too high. It's not a surprise they sound bad.
Rite they need airspace!...those things bump!...and are very underrated @ 150 RMS each!...they take more than that and they have a high sensitivity @ about 91db so they need very little power to sound excellent in the rite enclosure!...they need a ported box tuned at about 35hz
Nice build, I like the fact that you made the subs downward firing, I am considering dual 10" Rockford Fosgate sub woofers for my Chevy Silverado crew cab, but they won't fit front facing, only 8" subs can be mounted that way, I need to research and view other videos to consider the pro's and con's of this type of sub woofer box. Thanks for uploading this video!!
Those are late 90's subs. I had two of the 10" version in my Nissan Kingcab back in the day and they would rattle the metal awnings at 7-11 above the doors when I cranked it up. The problem is the 10" were designed for 1 to 1.5 cubic feet ported. The 12" version is probably in the 1.25 to 2 cubic foot ported I would imagine. So .62 cubic feet is nowhere near enough volume for those subs. Not even close. Just checked and for the 12 it is 1.25 cubic feet for sealed and 2 cubic feet for ported so yeah box is way to small for those subs so it's going to sound like utter dog crap. www.manualslib.com/manual/284695/Jbl-Gt1241d.html?page=2#manual
I thought I blew a sub before it ended up being a fried terminal I didn't see it until we were putting in the new sub always check the simple things first and this guy is very talented in my opinion seems like there is nothing he can't do
the distortion could be from the amp being set up wrong, gain, sub-sonic, low pass etc. theirs videos on how to set the amp up close enough just by ear and seeing what the sub does
Mate, you have done a great job with the box. I suggest you try them again with the ports sealed and see if you like the sound. Ported boxes tend to be larger so with the small internal volume of 0.6cu ft, try them in a sealed application before you put another pair of subs there. You have great wood working skills!
Nice box man 👌 just wondering if you played with gain on the amp?if it distorts turn it down a little.I usually set my deck flat and adjust the gain.just remember gain isn't a volume control 😉
I think you did a great building the box. Do you do any kind of wood working for a living or are an arborist with your dad it definitely looks like you have wood working skills I see nothing wrong with the box you built. No need to be so defensive you did a great Job!!! Looking forward to seeing it and hearing it when you get the other kicker sub installed. Have a great weekend and God Bless!!!
My opinion, for starters great looking box, JBL subs especially those ones have great sound quality depending on what amp u have, if the JBLs are distorting either one of many things are wrong with them the coils are toast and being second hand subs I’d say more than likely that’s the problem, they are under powered since the kicker comps have a lesser rms rating then those JBLs ur probably gonna need a different amp anyway as it’ll sound good with one kicker sub but as soon as u add that second kicker it’ll be under powered and won’t thump as hard just my opinion
That was an awesome video man I don’t care what people say you’re doing the best you can with the space that was available. Maybe try looking into the sub Wolfers they require less volume. They are made specifically for applications like this. But I love the way that you Use the router to finish the edges. I didn’t learn to do that until I built like my fifth or six box it’s so much easier to leave the board it was a bigger one and put it on anything come through and make it perfectly flush.
I've been subscribed for a while now, and this is the first time I've seen RU-vid suggest any of your videos regarding car audio. Nice work considering the saw/router setup. A little ingenuity goes a long way.
Great build I think when you added the port and the “divider” attached to the port which looked like you had to ports you lost air space and it changed the measurements
Love your box. It's perfect. Do you have the demo vid of it!? Would love to see and hear it. Get some kicker comp r shallow mount subs. They sound crisp and clean. Or sundown's shallow subs. They are the best ones and can take plenty of power and gives you more cubes to hit the lows. Can't say they'll hit the 60's but they can play a pretty large range bandwith
Good build bud you explained a lot that I am unfamiliar with so I'm giving you props. I'm a carpenter by trade and approve of your work, you did it with your own hands and mind. The dorks that are hating have to buy theirs or their lives are consumed with stereophonics it is what it is I guess but I like building shit and getting laid lol you did good keep it up I'm looking for part 2 now
Mark at Car Audio Fab has a good video on measuring your box volume. Really important to put the space of the port, 45 degree corners, and woofer basket into your equations for overall box volume.
I’d also recommend using some caulking on all the cracks in the box and sealant or foam for the circle on the woofer terminals.. otherwise an air tight box ported box is pointless if air will be escaping out the terminal. You did a good job overall!
Anybody who knocks Car Audio, must truly hate sound, isn't an engineer or fabricator because the education you need to master each trade: wood, metal, fiberglass, 12V electronics, sound deadening, and acoustics just to name a few is a genuine Craftsman.
you can fake out the speakers to "THINK" they are in a bigger box if your space is limited with Poly fill or pink attic insulation (the itchy stuff) inside the box behind the speakers- it will slow up the air in the volume and make the speakers perform as if theyre in a bigger box
Eclidean You're correct man but I'd stay far away from pink fiberglass insulation (the itchy stuff) for a ported box because every time you crank it up the truck cab would be a blizzard of all those itchy insulation particles. Ones that stuff gets in to your seats you're pretty screwed. You'd be an itching mess for as long as you owned that truck.
Yes but only so much. When your box is almost 1/4th the volumes needed, your not going to make up the other 3/4's with polyfill. www.manualslib.com/manual/284695/Jbl-Gt1241d.html?page=2#manual
i used to do this for a living. you did fine, most of the time you dont have room for the "ultimate" box size and just go with what fits in the space. we ported for 20hz most of the time.
it is made from sawdust glued together into a sheet like plywood. You want the 3/4" stuff. assemble it with screws or air driven staples AND wood glue.
Hey i think you did great job, i do alot of the same stuff you, there is always a critique out there that has something to say but i like what you do cause its not always about doing things by the book, thinking for yourself and doing things your own way make it unique and one of a kind bro keep up the great vids, and think "outside the box"
Get some polyfill and put inside the box to help with any distortion you may have at higher volume settings. You can get it at walmart or any piece goods shop like hobbie lobby or get a cheap pillow and rip out the stuffing and put it in the box. Trust me it will do wonders!!!! Nice box build too!!!!
Only thing poly will do is trick the subs into thinking they are in a slightly bigger box. Distortion is probably being caused by the gain control set too high.
Dude I have nothing bad to mention. I went out and bought a used router/table, shop vac for the saw dust, multiple bits, and a saw. I'm using 3/4" MDF....but I'm drawing a blank! I have the tools but zero knowledge about what I'm doing. I'll eventually figure it out but it's not as easy as I thought. I'm trying to build a box for my 08 Silverado but I'm seriously having a hard time figuring out where to start! So, unless the people watching have actual hands on knowledge about what you did here, their opinion doesn't matter. You did a great job! Nice video too, btw.
It's all trial and error man. As you build your realize it "Ah man, could have been done better if I did this or that". Learn from your mistakes as I did. After you build a few boxes it gets easier. If the box has slanted faces be prepared to re-cut that slant- buy extra wood. I'm thinking about making a video showing how to build a simple box with a double baffle plate to recess the sub for a cleaner look. How did your box come out since it's been 11 months?
@@frankmaggio4328 I tried to get the image in my head to come out on paper, but I just couldn't get the measurements right. Also, the bits I bought were cheap ones on Amazon, and no matter which direction I was starting on, or how slow I went, the wood kept jumping off the router. So I bought another box specifically made for my truck, but it didn't fit... I ended up going to Lowe's, bought square tubing, and raised my back seats 3 inches. That gave me the clearance I needed, and it works pretty good for now. But I've been thinking about trying to make a better box, now that I have more room, maybe it'll be a little less stressful. What kind of bits do you use?
@@somanynamesilltrythis0180 well 3" isn't really a lot of room. If you want to make a box I would suggest going to Walmart and getting used boxes and packing tape. All you have to do is cut the box into sections to the dimensions you seek. Take your time. Basically taking up the space you want to use. The outside dimensions will have to be measured. There's a lot of math involved but after subtracting the 3/4" walls from the equation you will have your rough internal air space. This way you know "OK the external sides have to be 7" tall and width is 51", the depth is 12". People do this all the time when building an enclosure to fit in a trunk. If the paper box mock up doesn't fit they just saved themselves the hassle of building said box. Hope this makes sense
@@frankmaggio4328 that's a good idea, I never would have thought about making a cardboard design to transfer the dimensions. What's throwing me off is the floor under the seats isn't flat, it has a slight hump in the middle that spreads to the rear of the cab. If it was completely flat I don't think it would be so difficult. Thanks for the advice.
My honest advice is now that you know your airspace and if you want to use kicker go on their website and find what works it that volume. A properly sized and tuned box will sound better and play louder than one that is that far out of spec. If you insist on 12"s ported is just not going to work well with that small of a box. If you removed the ports and dividers making it one airspace you would probably be close to perfect for a sealed enclosure for 12"s though. Nice wood working by the way and yea mdf sucks to finish.
I realize this is an old video but for future reference I guess I think if you would've used a rag to apply the stain instead of a brush and rubbed it in while basically spreading it out and wiping it off at the same time (if that makes any sense at all) then it may have came out more uniform. Not sure I've never stained that type of material but just a thought. That's a sweet box
Tengo una ford lobo lariat 2010 4 puertas...quiero poner un par de subwoofer debajo del aciento trasero porteados..que bajos me recomiendas que sean de buena potencia ya que cuanto con el JLAudio slash 1000.1 y si pudieras ayudarme con las medidas del cajon y la medida del porte que debe de llevar me seria de gran ayuda..la verdad me gusto mucho tu trabajo y sobre todo que todo lo hases a la medida segun pidan los bajos y el carro..exelente video amigo👍
A few suggestions, 1 plug the port with a hand towel and compare to it open, 2 most factory ported boxes are tuned between 30-45 Hertz, 3 put in Usher (Yeah) and try it both ways and ported you won't hear the deep 20 Hertz bass notes
Hey Bud, stop worrying what they say in the comments. Do your thing and if they don't want to watch it, then screw 'em. Keep up the good work because I enjoy watching your videos.
