how loud will 4000 watts be

[mat3833 10+ year member]

Lol, this thread=fail.
But if I recall what a "professional audio salesman" told me (this is a true story)

When you plug a subwoofer into a 120 volt wall outlet it will play them at 120 decibels, and it's not the power that kills them it's the frequency because almost no subwoofers can stand a 60 Hz signal. So 4000 watts at 1 ohm would mean 63.2 volts=63.2 decibels. Sorry man //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

wow, do you actually beleive what you just typed?? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif if so you should go back to school. 120V house current is AC current, which is what speakers run off of. 60 HZ is actually perfectly do-able for most speakers larger than 6 inches(and some that are 6 inches, just depends on the design) 120V does not = 120DB... your house wiring can basicly put out however many amps you need as long as the breaker doesnt trip or the wires dont fry. so lets do some simple math:

120V X 10A = 1200watts (V stands for volts and A stands for amps, u follow??)

120V X 40A = 4800watts

so lets say your "plug a speaker into a wall outlet" scenario with a 40A breaker would give at least 4000W. that sub would play a consistant 60HZ tone(actually its more like 57-63HZ, it varies a bit).

the output in DB would depend on the actual sub used. id go into calculations on how to figure out an aproximate DB reading but i dont think you havemuch higher than a middle school education.

oh and power doesnt kill subs, HEAT AND/OR DISTORTION do.

and one more thing, i have no clue how u came up with the 4000W at 1 ohm = 63.2 V. i guess i must have slept through that part of engineering. enlighten me if you dont mind.

dude calm down he was just kidding LOOL!!

I'm not kidding that the guy said that, that part is true. That's why I put "professional audio salesman" in quotes. Thought that was obvious.

Anyway, tell me, how do you set the gains on your amp? Use a multimeter. Turn your stereo to about 3/4 power. If you have an 800 watt amp at 2 ohms calculate it as volts squared divided by resistance=8000. So volts*volts/2=800. volts*volts=1600. square root of 1600=40, so 40 volts at 2 ohms will put out 800 watts.

Now, to figure out what 4000 watts is. 4000=volts*volts/resistance. If the resistance is 1 ohm, 4000=volts*volts/1. 4000=volts*volts. Volts=square root of 4000=63.2 volts.

Seriously: I've used "LOL" a million times in my lfetime, but I have never actually laughed out ****ing loud until now lmao

I'm still not even sure if this thread is serious or not??? I just don't know lol

this thread just needs deleted... i just wasted 5 minutes of my life reading it...

lol, i missed the quotes. my bad man. thanks for explaining the whole volts / ohms thing, never knew how to do that.

sorry but i get pissed when pple post stupid shit. im a noob, and ill admit it. but i know alo about what should happen or should be happening. i have heard alot of diferent sterios and that is what i make my comments from, personal experiance.

oh and i dont set my gains, i let professionals do it. havent had the guts to set shit up myself thus far, dont want to blow anything. but my next settup i will tune myself.

i got a boss 4000 watt amp and im wondering how loud it would be i want them to be able to hear me before they see me.

i saw the title, and had an "lol" moment

came in, saw this and almost died //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

i'm gonna go with "what is, amps don't get loud, Alex"

 

[Mass Car Audio 10+ year member]

ya but i want it to bang more then once.

Hit it with the hammer more than once then. Or go pick it up off the ground after you throw if off and building and do it again.

HEAT AND/OR DISTORTION do.

The distortion isn't the killer, it's the heat generated by the extra power since there is more area under the curve. The only way to kill a sub is thermally and mechanically.
