the sound of that door shutting bring me back 18 years ago to my first car a 93 gmc Jimmy slt awsome lil rig!

I ❤️ how u r explaining the nuances of a quality build. Ppl hv no idea how to do it right. Preach brother 😆

You sir have created a complete spl beast. That's awesome

Wow! That's a great start.

Looking good ! Lots and lots of work paying off!

Nice!!! & yes indeed you had me going at the end.

Tease that hot sauce, then give us mild!!! You got me good! Love the videos. I'm tuned in and waiting to see what is next!

Great info brutha....I'm learning alot since starting this SPL project.

Great advice on the sweep and not playing full tilt

Pure content** real followers jump for this no matter what time it is 🙌

FREKIN SWEET BROTHER IT GOING TO BE AWESOME!!!!!

Love your videos BTW watch you all the time

Lol you tease... Wow bro that is crazy hitting like that and really just breaking in. Cool stuff 👍✌

Awesome!!!!!!

Awesome video bro. I had no idea of the testing that needs to be done on a build like that. I can't wait to see what it does when it's finished at full tilt.

Good video. I usually want to start this max 10db down from max decibels. Even then my peak frequency isn't fully accurate, one time I peaked at 32hz (about 30hz tuning) and real peak on full tilt was 52hz with less than half power 😃

Great information ty!

You a freaking legend man!!!

Like the blazer clean setup

thanks man helpin me learn more

That was a huge jump in power from 60hz to 69hz.

CD CD'S what is a CD? Never heard of a CD? You mean they have them yet? Just playing bud! Great video as usual! ALWAYS informative no matter what the topic is! Ty

Myrtle Beach bassheads here. We love the videos keep them coming! Have you guys thought about throwing some compact NEOS in there just to see what the difference is?

Agh u played with my emotions SMH great job that shit is gonna rock I say 163 rite now an 168 with the wall finished great video keep them coming bro

Definitely puts power increase to dB increase into perspective!

BRO! im fizzing at the numbers your doing now!!!! #buildgod

Probably the only video that REALLY explains how to find peak frequency.. IMO.. What model pioneer you using?

haha cracked already. nice video

Great video. This is exactly how Ronnie Smith found the peak in my kingcab hardbody. Is this also related to vehicle resonance frequency or is peak just another term?

I wanna see you go full tilt on that windshield let the chaos commence !!

The loading wall will make it hit way more spl. Can't wait to see that video man. Good job

Darn! Thought you were going to turn it all the way up! I'm sure the windshield would definitely be history if you did that. Glad it's playing though.

Great video very knowledgeable but quick question I have a 7K amplifier how much battery power do I need to push it on 2 15 1ohm 3000 RMS x2 so 6000 RMS

So once you put all the juice into the subs you will do the same 68 69 70 71 etc with all volume up to clipping?

Yo brother i know this has nothing to do regarding title but i was just wondering if your bass tubes were designed for those ultras or ultimately the zv5s you plan to switch out to in the near future??? Also with the subs basically being in sealed tubes and no air ports are they intended for spl onl only or can they play music as well without alot of heat build up on the motor??? I appreciate all that you do for the car audio world!!!

BITD we ran pink noise through and watched the RTA for peaks. Typically the hump was resonant frequency. I don’t know about that software but if you can watch all frequencies at once in real time it will get you closer quicker than sweeping from 20hz up.

I saw that 163.7 at the beginning of the vid😉

Great method, sweeps are just completely useless because they are too quick. My personal method that many people love is to use when I show them is a sine wave app (I personally use the xplicit audio ultimate car audio app with their tone generator). Within their program you can type in any frequency you like and you can hit the + or - buttons to go up or down in frequency, and you can do this without stopping the sinewave from playing as well so it kinda simulates a very low sweep. And since it's continuous you can easily tell to the ear which is the loudest (obviously this is used in conjunction with an spl meter as well, but you could totally get away with not using a meter for a very close peak freq estimate since you can tell by ear if you didn't happen to have a mic on hand). Your method is technically best though because it simulates the exact spl scenario as you would in the lanes and you wouldn't get the voltage drop associated with playing longer tracks. Great video though man some people really needed to hear this lol.

Can I ask is this what cabin peaks at ,,, I get confused or is this where your enclosure tuning is peaking

Thinking too but some sundown subs

Hey BTW :I've got 2 s10 blazers I'm gna junk. If u need windshields. Perfect condition. 😊

Do you guys think your SAs 12s are louder (bass) than Kicker L7S 12s (44L7S122 which are 750RMS)? Serious question bcuz I want to upgrade and am considering SD SAs 15s, EMF LBs 15s, or Kicker L7S 15s. Don't get me wrong, my two 12s can easily be felt from blocks away but like most, I'm craving for even more!

You should do a few burps at some lower, more "musical" frequencys. It would be interesting to see the real world bandwidth of such a strictly SPL build.

Wouldnt it be louder wird ported tubes? Just wondering

Does the term lab display not detect above 70 hz?

Now that you know the "peak frequency" how do you think the loading wall will affect the frequency and the output?

Very nice man. On your loading wall, is their a rule of thumb or just build it? Add or take away while tuning?

Whats the difference between skar and sundown ? Prices or ??

is the rise in power because of the impedance curve? rhetorical and with more power what is your actual peek? wouldn't you need to test freqs with all the same power? 80 watts at 60hz and 345 at 71hz thats 4 x the power your spl should go up with more power. at 60 hz and 345 watts what is your spl? or am i missing something?

Selfie Dustcaps #FTW 😎

You was pulling a 150 on around 500 watts that's the cone area for you I pulled a 132.8 on a single 12 in my daily driver ( minivan ) stock everything except head unit ofc 6gauge and my amp 1250 at 1 ohm it wasn't until that day I learned my hcca Orion was internally bridged on the coils to 4 ohm pulled 458 watts lol

You dirty Birdy I thought you're gonna turn it up lol

AWESOME 69 HZ AT 160.0 AND 12 CLICKS IN. CAN'T WAIT TO SEE HOW IT GOES WITH THE LOADING WALL

What head unit is that

Nice! But when you go up in power, you should double check to see if another frequency pulls ahead. Mine peaks 50 hz in low power but at 31.5 hz on high power. So it can sometimes be good to go back and check a wider frequency range at different power levels 😉👍🏼

Great numbers man! How much do you think your loadingwall will lower your peak?

What is the frequency of a toyota yaris sedan 2007

How much do you expect ur frequency will change after ur loading wall d

Im sorry im stupid how does this help without a loading wall is that what your going to tune to or a little higher. Just a little more detail im lost how it helps without it loading or does that not matter to peak frequency but if not, wont the wall provide more area taken up result in a different peak frequency. Please explain a little im well versed in this but that got me or im too tired to think right now.

Do you still break in subs when using them only for burps or does it not make a difference? And do you have to re-calibrate your tuned frequency as they break in?

166.3 no loading wall at 69 hrtz full tilt. ..171.2 with all amps and loading wall tuning will be around 67........

Are the tubes a worked out volume ? Or just guess? Will you use the same tubes on both the U and NSv4?

It would be awesome to see you do a build where you're pushing above 160 in the 20 to 30 Hertz range that's a little harder to do

So once you install the loading wall will your peak feq change? Or just amplify.

What kind of box is this

What is the Ratio. Looks big from the size of the tubes compared to the box but it’s hard to tell with the fish bowl lens. How many cubes are the tubes ?

I had a box tuned to 34hz but when metered the cabin peaked at 55hz is that normal

Sundown Audio unofficial Gosh damn 160 is Loud as Heck 🔊🔊🔊🔊🔊🔊🔊🔊🔊🔊

I may not be right but I question if that’s ur current tune being that every time ur dB went up the power seem to jump a fair bit, wouldn’t you be better off testing each frequency at the same power to make sure u find the most efficient frequency? I no in my burp car 100w can be a huge dB difference wen it comes to frequency’s my guess is ur peak may actually be more the 67-68hz But sorry if I’m wrong lol

TermLab power clamp does power factor as well doesn't it?

69hz? Nice.

Bro I don't know if I missed it because the videos are lomg and can't see all of them. Will you wall the front of the box?

You can hear the peak at volume one, using a sweep.

Use 24 bit wav files they have 144 dB of dynamic range vs 96 dB of the 16 bit wav CD .. 6 dB per bit... the noise floor is less & there is more dynamics in 24 bit audio. A mp3 is worst due to is being lossy and removing parts of the frequency range, the lower lows & highs and the bit depth ( noise floor info included ) is removed for either variable bit rate or constant bit rate.

Play some Psyph Morrison....Wet Dolphin....Go For The Money......Turn It Up....these 3 are just a few that will throttle them subs bro 👊. Get'em play'em and upload that vidoe please 👊

This year i wuld need a sponsor to sundown audio in Sweden but thear is no in Sweden

Damn

WHAT MODEL PIONEER?? I seriously going to buy one once I find out that model.... 🤪👊👍

😮🔊😮🔊😮🔊😮🔊😮🔊

How much is that amp and subwoofer

But..... was it the loudest? Or just where you made the most power...

Won’t your peak change when you add the loading wall?

Won’t the loading wall change this?

thats fucked up lol good video

I know what y'all waiting on. Y'all want me to turn it up. (Lord of the rings Gollum voice) yes yeeees YEEEESS! Naaaa I'm not going to turn it up. (Old drunk dad voice) WHY YOU LITTLE SOB! Tears :(

all that room and no ported box?

That was a dick move not cranking it 😂 lol

Got turned on when you said "Rock Solid"

I hear it ain't gonna touch the terra tho...lol guess we'll see.

It's gonna change again when you add loading wall and more power. And just think that's 160 with no loading wall

That poor stock windshield didn't have a chance, with only 1 amp installed.

164.7 db

0.0 -163.7 😁😁

No we're waiting on tge rest of the nsv4 woofee test

im gonna guess a 162.3 with no loading wall

A 150 at 800 watts. WTF...

Loading wall??

I used a pink noise signal (all frequencies at once) and determined my peak to be @ 58 hz. So I went straight to my DSP and flattened that peak completely out. Then, where it tried to roll off, below 30 hz, I bumped that up a bit. Not trying to build a burp box. SQL is where its at. If I were just trying to be "nothing but" loud, I wouldn't even run mids or highs, AND I would chop everything below 50hz + everything over 70 hz..... and then feed it a really strong 58 hz signal. But I digress. LOUD is easy. SQL is music to my ears ;)

Bro put the computer and stereo somewhere else. I get nervous when I see things on top of amps or speakers lol

69 hz? I think it feels good.
