anyone ever try to meter a wall socket burp ?

[brian84corvette 10+ year member]

it just occured to me one day - i always see people post videos of subwoofer destruction by free air wall socket death - but has anyone ever actually tried to hook up a term lab or other metering device and give their car a "legal" wall socket style burp ?

what do you think the numbers could be ?

do you even think 150s could be possible on a wall socket burp in a strait up burp setup car ?

if anyone has done this yet please link me a video id love to see it

Find someone running 10kW who burps at 60Hz and you'll have your answer. ;-)

I **** you not, I was contemplating this last night. Wouldn't even need a hu. Just decent electrical, a box tuned to get loud as **** at 60hz, and the beastliest ac inverter you can get.

And a light switch, lol.

You clearly don't understand the idea of the wall socket burp. Decent electrical is completely uneccessary considering the power isn't coming from the vehicle, and an ac inverter? *facepalm*

As others have basically said, connecting a sub to a wall socket is the same as feeding one a 110V 60Hz signal, which IS possible with regular equipment. There's subs out there that can handle that amount of power for a good length of time. 110V AC is approximately equivalent to 12000w at 1 ohm, I've seen vehicles running much more than that, but to answer your question if you burped for short enough periods, yeah you could produce pretty good numbers running straight from a wall socket.

I believe he's talking about using it in an actual competition... lol

let me add another aspect to this idea = ohm load from the subs...

lets say i hook up my re sx 18" with dual 2 coils to a 4 ohm load to the amp ( or actually to wall socket )

not factoring the rating of the circut in the breaker box ( 10/15 amp all the way to 30 amp circuts are generaly used in normal homes )

rough idea of watts going to sub once pluged in to wall at 4 ohms load ( is box rise a potential issue here as well ? )

what if someone had a pair of dual 4 ohm 12s and wired each to 8ohm and together for 16 ohm = wall socket power at 16 ohm load = ?

the idea of this post in my head was just for fun. but to place a meter in the viechle where it normaly would go to post a legal score in a comp

so that the results can be compaired to viechles using actuall big setups with mega power and $$ vs the cost of a sub / box / and a piece of cut off electrical cord

P = V^2/R

So at 1 ohm, 110V^2 / 1 = 12100W (110A)

2 ohm = 6050W (55A)

4 ohm = 3025W (27A)

8 ohm = 1512W (14A)

16 ohm = 756W (7A)

So realistically an average house electrical would only sustain an 8 ohm or greater load for any length of time...

A true SPL setup that was not designed to peak at 60hz would not do as well on even 10K (assuming you're getting anything close to 1 ohm at that impedance to begin with). as it would at it's designed resonance on a quarter of that power. Real SPL vehicles have a very narrow bandwidth and you can start to drop 2-3dB per cycle once you stray away from the intended frequency.

Second of all, if you really need to run 110 or even 220V AC just buy a bunch of batteries and a big amp. Much cheaper in the long run than burning your house down overloading your wall outlets. IMO if your amp doesn't put out over 100V you might as well not bother.

o no i would never build this on purpose = its a purely for fun and watching the destruction of woofers type of a fun experement.

so maby what if you had new recones show up for your pair of 15s walled off in your honda - and before deciding to tear down the functional drivers you could drive over to a buddys shop / garage and set up a term lab mike in a legal type placment and wired the subs up to wall socket for a burp to their deaths, while video taping the whole experience for fun.

i wonder what the score might yeild just purely for fun - vs every other person on you tube doing free air wall socket subs to death.

Not really. Was just thinking the other night about what would happen if you built a one note wonder using an ac inverter... for shits and giggles. I didn't put a whole lot of thought into it, as it was an idea that came and went.

I'm not sure why trying to think of a way to make the idea work off an invertor merits a face palm. But if it makes you feel better about yourself, cool.

I metered my DD9515D off a wall socket 6years ago.



Pretty much just trying to kill the sub and get ready for a recone.

wallsocketing is not as much fun as you would think... I toasted two freshly built nsv2's just because I could. was fun until it was over. then I realized I just wasted a G.
