crazy amplifier application

JBL has a video of one of there amps powering a hack saw to cut another amp in half...pretty cool

What is the life of a hacksaw being powered by an amp? are there any modifications made to the hacksaw? is the video altered?

Ummm.... Like the OP says, electricity is electricity. Why would the life of the saw be any different? If the power applied is correct, meaning correct voltage, current and frequency, whether it comes from an amplifier output stage or the wall, what's the difference??

No. I've seen the video... I'll try to dig up the link for you. It's a standard Sawz-All.

As a marketing gimmick, I can see how you would think that Harman would WANT to alter it, but, as I said, I've seen it, and I could sense no alteration.It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I'm obviously talking to a group of electrical engineers here, so I'll shut my mouth.

Dude, don't take it like that... We're all here to help with understaning. I was just trying to find out WHERE you weren't understanding so I could help in that respect...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice.

I was kidding. Have fun getting worked over. Bye.

Cutting through another amp? Sweet!! I'd love to have a job where I get to do that. One other thing why I think it would work, is because it would only require a short burst of power because the hydro pump would not be in use for more then a second or two. Maybe I could incorporate a 1 farad cap?? Also, does anyone know how to figure out how many volts an amp would be putting out from the amps watt rating? Thanks

rockford used a two channel amp to power a sub and a blender at a training I was at once... tasty margarita!

3000dClass- Yes, but only if the impedance or amperage are known. P=I*V V=I*R P = Watts V = Voltage I = Amps R = Resistance Using the above equations we go from V=I*R to I = V/R. P = I*V, so substituting P = (V/R)*V. Simplifying, P = V^2/ R and ultimately: V = sqrt(P * R) Therefore, for 100 watts @ 4 ohms (typical speaker load) V = sqrt(400) = 20 volts. d-
