Dmm number

[darron016 10+ year member]

So 3 people have gave me 3 different answers.. I have a mono amp 1200X2

So I did 1200X2= 2400 Than took the SQ of 2400 and got about 48..

Someone else got 69 and someone else got a 17

So there's no dispute or question when you're doing this

it does 1200 at 2ohm or 1200 x 2 channels?

1200 at 2 ohms

At 2 ohms

 

[darron016 10+ year member]

Volts = SQRT (500W x 2 ohms)

Volts = SQRT (1000)

Volts = 31.6VAC

This is from your link @neo_styles

It did Watts X ohms first than the SQRT

If I did the Sqrt of 500 than multiplied it by 2 I would get 44.7

I'm doing the best I can not to vent right now, but we were handling this by text. I'd appreciate it if you demonstrated more tact.

You're making it harder than it is.

(rms of amp x ohm load)

take that number and sqrt it.

At 2 ohms

so then its 1200x2=2400

sqrt of 2400

=48.9 vac

So if you're trying to set at 1200 rms @ 2 ohm you should see ~49
