Where's .707 at ?

only way you can draw any sort of conclusion like that is if you test the amps head to head in that install

Otherwise that's like saying oranges taste better because i say so.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

.707 is to get RMS power.

First thing. The numbers put up are for tones. If I remember correctly you dont need to find the RMS, the number is the RMS.

Second, I do beleive that the clamp they used was a ture RMS clamp, so the numbers are correct.

I am still a noob at this, but I know the numbers provided are accurate. I was there.

Right...

RMS power

What happens when the coil goes forward..

And then the coil goes backwards...

Resistance is changing through the entire stroke, the entire time.

Along with the heat of the coil heating and cooling...

So what is this supposed to do, take out the 'peak' ?

Wait...isnt this "peak" what you get when you burp the sub?

So you even multiply by .707 when your using a nominal 1ohm resistor...even though current, and voltage and resistance never change?

You humor me....alot....

 

[NDMstang65 10+ year member]

Wait...your just multiplying the voltage times .707????

Dude...no.

Where's the current go?

You can't not use current and get a true wattage reading...

I'm not even going to waste my time, keep doing what your doing....

I have always understood to multiply by .707, even when using true RMS meters.

voltage x current x .707 is what I have always used...

what your talking about i have no idea.

You only use that when you have a pure sine.

IE: AC voltage only as in an electrical outlet in a house that is 60Hz, only 60Hz and is not clipped/distorted/square waved at all what so ever, not out of an amplifier in a car....

Current x Voltage = close as your gonna get.

.707 = for only pure sine, and the odds of that happening in a car are slim to none.

Why would the amp not be putting out a pure sine wave?

Why would clipping mean you no longer multiply by .707?

Why would me sending 60hz through the amp be any different than measuring 60hz from my outlet... could I not set the amp to put out 120v @ 60hz and power any AC appliance the amp could handle?

Which btw... "your hero" noted the 2500d would do around 3500 watts on a good 18v system, which is just about right on par with my 3300 RMS watts from a 16v system... I doubt he was talking about max power in that situation.

Nevermind.

Some things are better left unsaid.

Carry on with your parade.

JBL did it...it's on their website.

someone got a link to this, i cant find it but i sure wanna see it

I'm just trying to see your side of things...

oh well.
