I'm sorry man, but I'm glad your daughter wouldn't let u do a wall. It'll be better for most ppl to relate to cuz most ppl only have 1 car, and not walled ya know! I'm pumped to see how ya make it happen!👍
You are A1 for dropping so much information dude all the time
Your videos make my day man keep them up
Designing a enclosure is a true skill
there's just a lot more to it than people think.. it takes a good bit of time to do right
@@JerryAintloud oh for sure spend hours on it then decide to redo it again
It's wizardry that I will never fully understand. That's why I always stick to sealed enclosures lol
Nice plans, meaningful arguments and recommendations, and sorry for the long comment 😅. I am still learning things about enclosure designing, so if something isn't correct what I wtore about, pls correct me. Just few things what worked for me when I designed an enclosure for a car (at least for those drivers I worked with): some designers have an option for including cabin gain into the simulations - for example BB6 or speakerboxlite: back then for 1 of my friends I designed a sub for an 12 inch Edge driver which was C-slot-ported (L-port + 1 piece of extra wood), tuned to 25 Hz, but it was peaking in his car right at 20 Hz with opened window - when I switched on cabin gain, the transfer function graph showed this (also over the internet once i found the formula and tutorial how to find the cabin gain's freq of a car) - so, with cabin gain it is more easy to design a windy box. Usually for cars I design boxes in which the driver just touches it's Xmax at a higher freq than tuning freq + at 20 Hz on the driver's RMS power, using slot port with an area which gives 17 m/s max port air velocity (if I know right, in theory max port air velocity of slot ports up to 35 m/s is OK, just over 17 m/s needs to have properly rounded over edges to reduce / cancel the port noise). If the port needs to be long, then to keep the box buildable in the most compact way it is possible, design labyrinth port - on speakerboxlite is the easiest to design a labyrinth port i found to date (maybe there's an another designer - I don't know). Try out more designers: for example I designed a box which had net volume / tuning freq / port area / port length the most realistic by WinISD, another by BB6, also other by speakerboxlite, just the final designs I made on speakerboxlite using these most realistic specs.
I can't wait to see what all you do with this jeep brother. I love seeing awesome daily bangers
What Mod/Tank do you have? I use Mod: VandyVape Gaur 21700 Tank: HorizonTech Falcon 2. Love your vids brother. Power of beard!!
Paul designed me a box for my g2 18 genesys and it had 13 square inches per cubic ft and tuned to 29 6.5 cubes and I had it on a Korean 6k I couldn't hairtrick in my suv for crap I have 4 12s and I shrunk the port area lower on my new box tuned to 23 8.3 cubes and I can finally hair trick Paul's box design got down tho just no hair tricks but now I can
the lower tuning helps a lot.. how many inches per cube do you have now ?
Can't wait to see it. I'm running 4 12s on a soundigital 12k and can almost hair trick. Almost. If my port was little smaller around it would. It's 13 inch octaport. We did port wars and it did a 164.3 half way in port. First time really building a system. Now I'm attempting to build wall so we shall see lmao
that's awesome, and walls are just fun.. i love having a wall build.
Yea it's crazy how loud one can be and it not hair trick some vehicles don't do it weird huh.
Sounds like a fun build. Too bad you couldn’t use passive radiators since they don’t consume space in the box like a port but they can cost unless you have some old subs with no motors.
I use sub box pro calculator and just crunch the numbers to get my port and cut sheet to even numbers 🤷🏿♂️
Haha I've done that and have like 4 tabs open with different designs lol. 2 15s two, three and six 12s lol
Diagonal Slot port for the uniqueness 👍 Jerry... just an idea'r 😉
Your videos are very informative 👌 for the kids... you are awesome. Thanks for taking my jovial-ness. 😎
Personally I like 12-14in per cube but you gain pressure out of the port and also keep cone control.
Are you concerned with chuffing when you are designing these enclosures to do hair tricks? (Genuine question)
Drew is the man on the fourth did design for single fi sp4 15
Too much port velocity makes port noise. Just test it out. If it's too noisy. Make it slightly bigger.
Where do you set your crossover at for your subs ? Just curious 😊 Tia and happy new year!!
i set at 45hz and subsonic all the way down.. but I play lows
Thank you Jerry, I have an 06 wk with a 18 inch zvx on a taramps 5k bass .5 to 2 ohm it hits hard for what it is , she will float a rag but no hair trick yet 🙂
Hey I'm sure you thought about this but go port part way inside enclosure and part way out side.. load everything up and reinforce the headliner with wood, bracing, glue and foam like you usually do.. just use the windows and cab as part of the enclosure.. 🤔
So pretty much a cheaper 6th order bro..
You could always do a window separated wall to load against... to tube a 6th order
So you can say it's not a wall... lol kinda like Doug's bass ASTRO van with windows to see subs... 🤔
Just load everything up and wood on the roof and foam fill all panels.. lol go ham
I had messaged sparky to buy 6 of his 15s and have design me a 6th b pillar didn't get a response so I hit up drew for the design my current box is a sub up port back for 2 18s he designed it also so we going to try one of his sixth
i got 8 inches of aero port per cubes with two sundown xv2 15s and it moves alot of air and hairtricks
That's small
@@SheikhN-bible-syndrome does a 151 and floats rags from the trunk. plays down to 20hz no prob.
@@2015GTPP well yeah it will play down to 20hz because it almost can't unload do to the port being so small
@@SheikhN-bible-syndrome yeah demo wise having port area on the small side is better. if you are going for spl than yeah big port it whats up but for demos and playing low and daily listening, smaller port wins
Yeah, low tuned ports.....
Was designing my No wall box for 2 DC XL18s isobaric for my ford Fiesta
tuned it to 25 Herz and I realized: AAAAAAAND there goes my Centre console :-)
Help please, say a single sub needs 16 sq inch per cube, a single sub in 2 cube needs 32 sq in, does adding a 2nd sub double that and turn it into 64 sq inch of port area? So that each sub has its 16 sq in per cube? Sounds crazy for that much, but I haven't found an answer anywhere that says port area is per cube or port area is per cube per subwoofer? Dual x8v4 going into 2 cubes thanks
You should make a shirt that says "my buddy billy"
😁😁😁😁
What the f***
If you ever look at b2 audio subwoofer box specs there subs require small ports crazy I built my at 15 per cube I’m curious on the 13 increasing velocity I think it will.
it will and it'll help with the lows. more aid for suspension.
@@JerryAintloud you’re fkn awesome man I’ve learned so much watching all your content I’ve gained the confidence to build a ported box as opposed to a sealed and all to you man just like this comment here, you put so much first hand knowledge out big bro appreciate you for real 🏆
Can you give us the two box design guys you mentioned contact information please and do Chris do T Line box designs?
People keep telling me I can't do 2 18's in my 8th generation civic 2dr
But with everything ripped out of the rear and interior panels pulled
I've never built a box and am not 100% on the math but there is a bit over 25Cf total
I don't see why people say I can't build a 11cf box after all displacement is accounted for?
You can definitely get a Civic to produce wind. There's a Civic called Lil Windy with 2 18s walled from Grand Junction Colorado
Jerry what's good....
Got a question, this is regarding an Aero Port.
Big AZZ ports isn't selling 10" AERO Ports any more, so I bought 2 8" AERO ports. These 2 8" AERO Ports are too much... I'm really in need of just 1 10" AERO Port, length needed is 18 -20".
Are you able to aquire a 10" out there In Your neck of the woods.
If so..... lemme know.... I'll shoot you some $$$$ first, with a lil $$ on the side for you for the trouble and he'll I'll even mail you one of the 8", why not.
more port velocity doesnt get you hairtricks.
He can take the time to answer everyone's questions because he buys premade subs lol
Hey homie if my comments were considered offensive on your last video....not my intention...btw I'm 42....been in the car game for damn near 30 years...I was giving a true consumer perspective.... I know it's your responsibility as a representative of your sponsor to be positive for the hope of future sales...but be honest no one driving a daily gets sponsored....it's selling a dream... damn near a gimmick TBH. If you want to be the loudest in your small town cool....but when the majority of people were I'm from are pushing better systems without any sponsors....and if you're doing it for acknowledgement.....it won't work in your favor...you talk a good game for the average Joe... but people like me see right through the BS....keep it real homie. If you consider my opinion offensive...so be it.
9:12 are you going by net before displacement of woofers and bracing or after like what the sub is seeing I'm guessing after just want to confirm.
i get measurements and find gross of enclosure volume, then subtract the port at outer demisions so i get the wood for port also, then subtract subs and an estimate of bracing. and what's left would be divided by 3 to see what each sub is getting. so I have to keep doing this til I get the enclosure and volume for each sub right where I want it.
@@JerryAintloud right I followed what you said and used the 12volt calculator and designed a box that is 6.64 on sub side not counting port and after some bracing and subs the 2 15s should end up seeing 6.12 cuft and the port is 5.5" x 15" and 41" long tuned to 28fb. and 82.5 Sq in port area for 6.12 cuft 82.5/6.12 so I'm @ 13.5 cu in of port area per cuft and box is designed subs up port firing passengers side so it's louder for me. I appreciate you posting all this firsthand knowledge brother!! 🙏
Definitely noticed that the lower the tuning the windier the build gets Jerry. I'm currently tuned 34hz in my slot port enclosure and my range with my Sundown Xv2 is 23hz on the low end and 57hz on the high end, pretty musical but not quite low enough for my taste so I'm thinking about 6th order out the trunk next. 🤔
U can tune to 26 with a aero port and you’ll be more windier and have less sq in of port area
@@alberthunt8501 in a Honda Accord trunk? I'd have to do a T line to get the math correct vs aeroport
@@alberthunt8501 I talked with plenty of enclosure builders and they suggested the 6th over literally every design because I only want wind
@@alberthunt8501 there's literally no room for a aeroport enclosure for the port to be sticking out of the enclosure to not displace the air space inside of the enclosure itself. As I said T line would be a better option but I don't want a fuckin huge enclosure I still use my backseat
@@ChaosTherapy719 yep you will never go back to regular ported after that
I want a loop of 15:45 & 16:01
