i showed some of this LIVE this morning on my instagram channel - give me a follow and see some of this stuff way before it hit's youtube! instagram.com/meade916
The number of watts the enclosure is getting depends on how much impedance there is at 60hz. In the 90's Alumapro had a sales rep that would put a sub in a small sealed enclosure tuned to 60hz. He would plug it into the wall to show how tough the sub was. In reality the huge rise in impedance at 60hz prevented the speaker from receiving a large amount of power. (Ohms law). Lol this looks like exact opposite. Another great video.
It works because at 60hz AC woofers usually have a much higher impedance than they do at DC. A pure 1 ohm resistive load would pop the breaker instantly.
I feel like buying a Leaf electric car and plug in 2 subs straight to the power inlet plug and bump it.. who needs a Amp.. thanks SMD. Good stuff. Lol.
Bad ass man! I also noticed your older rack of Crown amps. I have 2 Comtech-800s, 2 ComTech 1610s, 2 DC300A Series 2, and a DC75. Love them all except when I have to move them.
Does your shop have three phase power? Imagine 480V three phase! Three channels 120 degrees apart. Get them sequenced properly. It would need a lot of woofers. And you'd need a serious amount of structure to contain it! It would be interesting to use variable frequency drive and sweep from the single digits to 100Hz or so. A few hundred drivers per phase built in a concrete bunker underground with a port venting to the surface tuned around 27Hz. That would probably do some serious damage.
I guess that wiring is limiting the current because my math buts .7 ohm at 120v at 171 amps which is like 20,000 watts but that like 16awg extension cord is bound to be limiting that
Those he's using are lvl 5 D.C. Audio probably 3 times the price of that type r and 3 times as powerful. If you got the cheddar I'd say definitely go for it.
This is the true definition of BassHead Fun! Master level shit all day. Hmm Next competition, pull into lanes, set up termlab, pop trunk, plug into socket get trophy haha.
To run it for longer put a lightbulb or heater as a ballast in series and run er at .35 ohms. Not sure what wattage I'd run for that I guess start off at 60W's for the light bulb to see if it creates enough resistance to not blow breakers. Could be a really fun experiment! haha
Pick up a big Variac Transformers so you can control the power it be a good way to break in subs cause you can take raw ac and drop it down to 10v all the way to 240v+ depending on the variac even a basic 20 amp unit is deadly that is 20amps at the voice coil wire them up at 4ohm or so as the current is what will limit you with ac power use a 240 single phase line and that 20 amps can really pump out a lot of bump but for this a powerstat 1156d is about the best bang for the buck 120v 50amps input with a peek output of 140v 48A
Those large power amplifiers are nothing more than variable frequency inverters. Pretty neat experiment, really! Box tuned to 60 Hz, roll up to a sound off, pull generator out of trunk (... well, maybe not, 10kW genset isn't going to be that light. )
When you boil it down, not really. Wire up an outlet to the speaker leads, play a 60 Hz tone, adjust volume to output 120 volts. If the amp is enough power, that won't be a problem. The only difference between a plain jane inverter, and a big power amp is the lack of frequency reference - the amp gets that from it's input signal. I honestly didn't think I'd have to explain this to electronics gurus.
Believe this or not......back in 1994 I wired a complete system with 12/2 house (residential) wire. I used standard plugs, outlets, receivers, and a 100 amp panel box. When I was doing the job, everyone thought it was a set up for an RV, not a sound system. Even though that was odd, the funny thing was all of the car audio came from Radio Shack! It was Optimus everything, subs, amps, and wiring. Crazy right?
steve im just curious about the calibration of your DB meter? it was reading 90 just sitting in the car... OSHA defines 80 as the max limit for exposure (in a workplace for 8 hour a day), and says a good way to gauge it without measuring is that you have to raise your voice to have a normal conversation 3 feet away from a person. it did not seem the case in your vid. anyways, that was an awesome vid. we used to do that to guys in the back of the shop with factory speakers they took out of cars. hook them to their power strips on the workbench so when they came in to work in the morning and flipped that switch, itd scare the hell out of them!
I thought after testing everything out you where eventually going to just leave it on and see how long they lasted, But it was still a kickass video though.
Daniel Harrell Absolutely man I completely agree. I don't have a 156db set up but I've sat in some comp cars. That higher bass is painful and even worse when it's cold out to me.
thats a bit much for subs ,from what little i know amps put out around 10v-100v so 120v @60hz shouldn't hurt them in a small burst but 220v would probably fry the coils
Correct me if I'm wrong, but the fuse he's got is a 20amp. He passed through it arount 35amps of current for a really short amount of time. That's why it didn't trip. It was a simple overload for around 1-2 seconds. If he holded it for longer the fuse was going to trip.
You're right the fuse won't blow, didn't quite give it enough time to heat up and burn. However you'd think your typical household or commercial breaker would pop within a specific tolerance. At 35 Amps thats 75% of the breakers peak rating. Same with the fuses, you'd think one of them would trip. I can understand the fuse, but I don't get the breaker not popping. The GE breakers I work on pop around 25 Amps, though rated 20 amps after 2 or 3 seconds of the short. Lol either way... Wish I had the guts to do this to my subs lol
Love the video... just plain having fun... i do beg to wonder what would it do with a box tuned to 60hz... the idea for world record spl with ac current makes sense if u gona be hitting 60hz..
NICE.. any ideas why dropping ohm load did not make more db? Im guessing the ac current that the wires could pull was maxed... Seeing as the breaker did not flip
Lol I'm late to the punch, I was wanting to wallsocket my 10s in series in a car, I did it outside one day around 13ohms 1100 watts rms "book power not true amperage power considering box rise" I heard that I caused some alarms to trip lol, those 10s hit 1.5" of excursion at 60Hz, I did it to another pair to get a better idea of the power handling and it went for 45secondbefore both coils unraveled. So I'd guess those ones at 100-300watt rated means recommended amplifier, they handle 150rms fine without getting hot so maybe 200 watts rms each I'd say is safe enough. Ofcourse if I did this.. 550rms each with cool off periods
Hey bro long time fan here... also badass Cadillac... hey shot in the dark but was seeing if you had anything laying around that you might jus wanna give away that I can add to my 02 single cab Silverado... just starting out fixing her up... if not that cool... but thought I’d ask hey bro keep up the good work!!! You do some badass stuff shit I have never seen!!! Well look forward to the next video...laterz
i showed some of this LIVE this morning on my instagram channel - give me a follow and see some of this stuff way before it hit's youtube! instagram.com/meade916
meade916 at least I know Google make my Bluetooth speaker and I need one you go boy painted for life
🤔
someone known intro song? :(
So how many watts does the wall put out? Pretty sure wall power is 60hz.
The way he jumped and said f that though... I'm still laughing.
we used to plug Orion XTR's into the wall all the time back in the day, fun!
It’s all fun and games until your house goes into protect....
LMFAO 🤣😅😅
Red light of shame
Lol
😭😭😭
Lmao! 😂😂😂
Oh project DGAF how I've missed you
Steve, I love working on cars and car audio. You give me motivation to get and there and do more. Just wanna say thanks!!
The amount that you go through just to play around. Love it.
I replayed the second hit on 1/4 playback speed and it read 7,015 watts for a second. Lol 👌
"If... you.. don't... know...me...by...now" Your playlist never get old. And shout out to Brandon the stuntman. He's always taking the abuse 😂.
The number of watts the enclosure is getting depends on how much impedance there is at 60hz.
In the 90's Alumapro had a sales rep that would put a sub in a small sealed enclosure tuned to 60hz. He would plug it into the wall to show how tough the sub was. In reality the huge rise in impedance at 60hz prevented the speaker from receiving a large amount of power. (Ohms law).
Lol this looks like exact opposite. Another great video.
240V 50A circuit with proper cabling next time !!!
"Where's The 220 Outlet At!?" Hold My Beer. 🤣🤣
I want to see it on 240v... Double the voltage and double the wattage.....
Great content, thanks Steve
It works because at 60hz AC woofers usually have a much higher impedance than they do at DC. A pure 1 ohm resistive load would pop the breaker instantly.
Last time I was this early
Eyeballs were popping out...!!!
MrMaxyield lmao everytime i meet a person witha lil bump i tell um about my boy steve and the eye
Steve the mad bass scientist. The whole time I'm watching hoping no sub blows. No more please us bass heads can't take it
That's awesome. The old 60hz test. Great way to ensure the warranty department will replace a device.
Grand ma ma’s lamp cord is back 🤣
This is the greatest video of 2018
When you have fun at your job... Goals!!
The Hank hills coming out at 7:12 interesting video giving subs 120v
That’s funny AF.
vintage smd type experiments i miss these
Never a dull day at your workshop, aye Steve, Haha. Those subs took it like a champ.
Wow what a work ethic. Hustlin 24/7.
keep up the great videos Meade, I always enjoy what you upload.
An the Mad Scientists of the year award goes to... this guy!
i did this as a kid. about 20 years ago. lol
joel champagne too bandit wasn't recorded 😭😂
I was so nervous watching this and I wasn't even there...
I KNEW IT YOU STILL LIKE IT MEADE THERE IS NO REASOM NOT TO LIKE THEM.
D.G.A.F. living up to its name
I feel like buying a Leaf electric car and plug in 2 subs straight to the power inlet plug and bump it.. who needs a Amp.. thanks SMD. Good stuff. Lol.
Hahahahaha, that higher range high wattage bass almost caused Brandito to make you a new moonroof with his head. Good stuff 👍👊
Bad ass man! I also noticed your older rack of Crown amps. I have 2 Comtech-800s, 2 ComTech 1610s, 2 DC300A Series 2, and a DC75. Love them all except when I have to move them.

What's he needs is 1.21 gigawatts from a bolt of lighting and a Flux compasitor then he will be working those level 5's. Marty. Lol
155.4 at 60 HZ. thats pretty good.
I guess that wiring is limiting the current because my math buts .7 ohm at 120v at 171 amps which is like 20,000 watts but that like 16awg extension cord is bound to be limiting that
Brandon's reaction to that shit had me dead😂
That was bad ass. Makes me wanna switch from my 12" type R to a DC audio 15" . 😁😁
Those he's using are lvl 5 D.C. Audio probably 3 times the price of that type r and 3 times as powerful. If you got the cheddar I'd say definitely go for it.
Recommended, but it's gonna need a proper box, proper power, and the right person to control that beast. I got the lvl 4.. worth the money.
whats next bro? harnessing a lightning strike to power subs??!!
Bout time we see project "D.G.A.F." again!!
Happy to see DGAF back. To me shes a popular as the caddy
Hairygun For sure..I love that thing
Try the dryer plug.
Technically Steve, 10*log(0) is negative infinity dB. Zero dB would be 10*log(1W) of output.
No civic time, I bought one just because of your videos. Would love to see if out and cleaned up.
"I'm gonna send this over to my 20 amp circuit"
300' extension cord hooked up to almost 0ohm load 😬
Lovin those crown amps on the rack?
SMD great videos!!!
That was SIC! Good job Steve
been missing this project!
This is the true definition of BassHead Fun! Master level shit all day. Hmm Next competition, pull into lanes, set up termlab, pop trunk, plug into socket get trophy haha.
Steve savage AF 💀💀🔥
just need to tune to 60hz and get a big ass variable transformer and adjust voltage as needed
To run it for longer put a lightbulb or heater as a ballast in series and run er at .35 ohms. Not sure what wattage I'd run for that I guess start off at 60W's for the light bulb to see if it creates enough resistance to not blow breakers. Could be a really fun experiment! haha
like it? I love that!
Didnt' Cerwin Vega do this kind of stuff, way back in the day? Nutz either way.
The mad scientist at it again subwooferstein
wow and my guess was higher, 3k watts at 165.3. thats crazy with just the wall socket.
Pick up a big Variac Transformers so you can control the power it be a good way to break in subs cause you can take raw ac and drop it down to 10v all the way to 240v+ depending on the variac even a basic 20 amp unit is deadly that is 20amps at the voice coil wire them up at 4ohm or so as the current is what will limit you with ac power use a 240 single phase line and that 20 amps can really pump out a lot of bump but for this a powerstat 1156d is about the best bang for the buck 120v 50amps input with a peek output of 140v 48A

actually they play music just fine.
I know that ( I'm very familiar with the inner workings of amplifiers )
slamdvw Then you would know there’s a bit more to it then just being a “ variable frequency inverter “
When you boil it down, not really. Wire up an outlet to the speaker leads, play a 60 Hz tone, adjust volume to output 120 volts. If the amp is enough power, that won't be a problem. The only difference between a plain jane inverter, and a big power amp is the lack of frequency reference - the amp gets that from it's input signal. I honestly didn't think I'd have to explain this to electronics gurus.
I have been wondering when we were going to see that thing again.
Nice video bro! Phill Collins - One More Night sounded good on background!
Steve wtf bro Lol you never seem to amaze me
Believe this or not......back in 1994 I wired a complete system with 12/2 house (residential) wire. I used standard plugs, outlets, receivers, and a 100 amp panel box. When I was doing the job, everyone thought it was a set up for an RV, not a sound system. Even though that was odd, the funny thing was all of the car audio came from Radio Shack! It was Optimus everything, subs, amps, and wiring. Crazy right?
I had a few of them Optimus amplifiers and decks back in the days.. they weren't too bad for some cheap car audio 👍👍
brian oliver no not crazy.
Selling my 3k ,Im just plugging into wall sockets for now on lol
Could use that wall in the living room. Jerry wire my house receivers to it should work for a little while, lol.
Crazy Bro! Love it!
steve im just curious about the calibration of your DB meter? it was reading 90 just sitting in the car...

Come to Europe Steve, here we have 220v on the mains.. I am sure you can get better spl score:))
And u have a lower hz. 50hz lol
I love the 14 ga power cable feeding all of that 2 gauge, maybe you don't need 2 gauge speaker cable? Just maybe ?
give it a whirl, let us know how it works out for ya!
I thought after testing everything out you where eventually going to just leave it on and see how long they lasted,
But it was still a kickass video though.
I wouldn’t imagine so. Why blow like $4,000 of damn near zero play time subs? That’d be stupid.
Lmfao, I love Brandon's reaction. 'Hook it up. Send it!'
Bring the Honda back to life ..
LOL try it again on 220?
156 at 50 to 69 hertz is ruff man great video I think u could run everyone sub with a 110 and be just fine
Daniel Harrell
Damn right man. That high range will make you feel like you're heart is about to jump out.
Kevin Ball 160 at 32 hertz is easier than 153 at 55 or 60 man that is a tuff vehicle to sit n
Daniel Harrell
Absolutely man I completely agree. I don't have a 156db set up but I've sat in some comp cars. That higher bass is painful and even worse when it's cold out to me.
@meade916 Is the beat playing in the intro a real song or just an instrumental? Either way sounds badass.
Still as fucking crazy as ever. Love it man. #BASSHEADLIFE
ohhhh yaaaaa!!!!
Hey, Steve.have us in Russia 1 head included in 220volt.but still fun to watch your videos.
Hey Steve, I have an idea.... I'm pretty sure you have a 220 outlet SOMEWHERE around your shop🤔
thats a bit much for subs ,from what little i know amps put out around 10v-100v so 120v @60hz shouldn't hurt them in a small burst but 220v would probably fry the coils
Steve you're crazy but that was badazz bruh bruh
He jumped like he got electrocuted 😂
👍
Hahahahah yessss !! That reaction when he got in the car hahah looked painful
Good shit Steve
I want to build a car stereo system in my room
Awesome!
Badass
Nice vid! Next time: three phase power ;)
4200 Watts at 120AC is 35 Amps, curious to know why your breaker didn't blow.
Correct me if I'm wrong, but the fuse he's got is a 20amp. He passed through it arount 35amps of current for a really short amount of time. That's why it didn't trip. It was a simple overload for around 1-2 seconds. If he holded it for longer the fuse was going to trip.

Side note, makes me wonder what 208 will do! If you have a sub that can handle that.
Would love to have a pair
That's nice.
"for use only where not subject to frequent flexing"
Bwahahaha I remember that guy getting a demo by bowman almost shit himself
Did this with a w3 on the ground once. Only took about 30 seconds for it to burn up lol
155 IS NO JOKE
Love the video... just plain having fun... i do beg to wonder what would it do with a box tuned to 60hz... the idea for world record spl with ac current makes sense if u gona be hitting 60hz..
it is tuned to 60hz
NICE.. any ideas why dropping ohm load did not make more db? Im guessing the ac current that the wires could pull was maxed... Seeing as the breaker did not flip

When are you going to finish this project Meade?
Mad man lol love the videos!!
Hey bro long time fan here... also badass Cadillac... hey shot in the dark but was seeing if you had anything laying around that you might jus wanna give away that I can add to my 02 single cab Silverado... just starting out fixing her up... if not that cool... but thought I’d ask hey bro keep up the good work!!! You do some badass stuff shit I have never seen!!! Well look forward to the next video...laterz
excellent I like to see your videos are good
Ur a GOD
scottyk lets not get carried away.
lol
