Time to Kill a Sub

[somekook 10+ year member]

nope. it doesnt just send out all the current it can without throwing the breaker.

you have to use the second equation. if you hook it up at 1 ohm, thats (220 volts/ 1 ohm = 220 amps) which is going to throw the breaker. @ 2 ohms its (220 volts/ 2 ohms = 110 amps) which might not immediately throw the breaker so you might get a few seconds of about 24,200 watts. @ 4 ohms it comes to 7100 watts, still plenty to blow the sub. even at 8 ohms, its going to give the sub 3.5 thousand some watts which will take longer but still probably blow it soon.

i can plug it dirrecty into the breaker box, it still has some open slots where the contractor hasn't put them in yet.

so if you bipass the breaker, then maybe you can get those 48 kwatts @ 1 ohm. blow the sub instantly or melt the wire in your house. bad idea.

my neighbor is building a home down the road he has a temp power supply that has 2 jeules hooked up to a 250 amp box. i'm sure that would melt the voice coild but i don't think i'm brave enough to do that

ohm's law...know it, use it, become one with it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

what about hooking the sub up to 480V 3-phase? heh heh...everything's much more fun with 3 phases //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

:hilarious You all make my days at work go by so much better and faster.

How did this all start anyways?

Well it all started last week when one of my 12" Immortals stoped playing, i thought i was weird so i pulled it out of the enclosure and low and behold the wire that connects the terminals to the voice coil was missing. I got pissed and called Audiobahn. The customer service manager offered to either replace the sub or refund me my money. I chose to have him refund me my money for both subs (i'm buying 2 XXX 12") so i figure before i send them back i want to see a super sub go pop.

at first we were just going to feed it 6000 watts rms and see if we couldn't destroy it that way. now i've been given the idea to plug it into the wall outlet.. no the real choice is to what outlet to plug it into.

A. 120 Volt @ 15 Amps

B. 220 Volt @ 100 Amps

C. 2 jeules @ ? Amps

D. the ground and power output from my firnds arcwelder.... oh the possibilities

i'm taking suggestion on how to destroy this sub... the onlything is it has to be from mechanical failure.

Lets see, we'll assume 4 ohms nominal...

Amps: (220/4)=55amps

Watts = (220*55)=12,100

This is at 4 ohms mind you. Figure in the impedence rise of the coil at 60hz. Im thinkin around 8-10 ohms.

With an imepedence of 8 ohms, power is cut in half. still, 6k watts is nothing to laugh at.

I wouldnt using a weldor just because you could be giving a full 100% duty cycle which unless its designed for it could damage it. I also wouldnt use three phase because it might burst into flames(which would be cool ) i would just use a 120 v wall outlet at 4 ohms you could have 3600 watts or 14,400 watts at 1 ohm.

Oh and get it on video

or a 220.

those plugs are messed
