This would mean 100W
This would be 23kW... but lets assume you meant 100W then your amp would have 100% efficiency which would make it the only amp in existence that does this.
So quite obvious your measurements are incorrect and the reason is you use MUSIC as a test signal which contains peaks that are waaaayyyyy to short to be able to measure them using a regular volt- amp-meter.
It is not pointless IF the right test signals are used.
Music is NOT such a test signal.
Music output can ONLY be measured with an oscilloscope.
And even then this will only give you the peak voltage values but at least will show you if you are near clipping levels or what voltage peaks are present.
To even measure that you will have to know your way around scopes to be able to capture such peaks (playing with single shot or setting trigger levels).
When you really want the actual power measured you will ALSO need the current clamp (or a small series resistor) and a 2-channel scope and then you would have to calculate the power levels. As impedance vary (and mostly in the lows where the most of the power goes) the power is not that important.
All you need is the voltage peak levels, not the actual currents.
They do not need power. You apply a voltage and it draws a current which will vary depending on frequency.
An amplifier is a voltage source with a voltage and current limit.
How much power is required (it is only about peak voltages) depends on how loud you play.
You can clip a 250W rated speaker with a 600W rated amp using music IF you play loud enough.
As said a few times..... IF you want to determine what power rating you need as a minimum to reach the desired levels (which is really what you want to know) then there are ONLY 2 ways to find that out.
When using MUSIC as a test signal you will need an oscilloscope and you need to measure the peaks occurring in the music signal. From there you can CALCULATE the required continuous voltage (is power rating).
When using test signal you can use a (cheap) multimeter but you NEED to do that with a dummy load. You should not do that using speakers !!!!
You would have to buy an 8ohm (500W dummy load (or lower rated for short measurements, you only need to measure during a few seconds).
I will tell you HOW to do this but only if you have such a dummy load. DO NOT attempt this method using speakers.
Of course i mean the input at 230 Volt was 100 Watt ( this is what the kwh Meter showed) and yes 4 Amps max 25 Volts max (but it was so fast it is not 100% sure) of course this means 100% efficiency what can not be max 90% with this amp).
But this is of course the not 100% sure measurements.
But 100 Watt Output out of the wall or 100 Watt input in the Amp and 25 Volt at 4 Amps is relativ close.

I used two of this modules one for an Speaker.
Iam sure i kill the RF7 Klipsch before this module clips (anyway i connected the two clipping outputs one for volts and one for current)... no clipping
But it is possible to let one of this modulesa clip
www.pascal-audio.com
But only when using one for 2 Speakers with 2 BTL iam far away of clipping, surely with full Power it kills my speakers.
But not sure if these modules are good , the measurement says not really.
If the are good i would buy two of these

And connect only one channel its rated 2000 Watt4 Ohm/1400 Watt ( oHm)
The measurement in the under 400 Watt range seems to be better than the 1200 AS1/2
Yes i can buy an ociloscope but i will use music for testing.
I have better multimeters for using at cars etc.
What i will know is can i bring my KLipsch Speakers with my music and an NCx500 Module to full output or will the module clip .
If it surely clips the measuremnt is unessesary than it is the wrong module.
Buckey says the NCx500 is not bridgeable.( I think he means his amp is not bridable).
Hypex says the new Nilai is bridgeable but with one power suplly the ouput is only 500 Watt but with two SMPS the power is 1000 Watt at 8 OHM, the KLipsch goes from 3,5 till 63 OHm.
Not sure if an bridged NIlai is worth it.
If not i go with the Pascal(Icepower till Purifi realeases their new BTL module.
Also i conected one of this modules.

One channel has also 600/1200 Watt but with 2 channels driven the output is only 620/700 Watt , but also no clipping.
So my idea was using one NCx500 with one Smpe (dual MOno) also rated 700 Watt 4 OHM will not clipp with my music.
But this amp i can bring to clip.

Its an Dual MOno Hyped UCD400 OEM with 2 Power supplies an some added capacitors.
But its only rated 400 Watt 4 OHm
