Thank you!!! Its exhausting trying to find the actual power output for some of these amps. I greatly appreciate you making this content.

I can’t find any information on these amps so this video was very useful. Do you know what power it will do on bridge mode at 8ohms?

Try yhe nx6000. Even though one channel is the same as an nx3000, it doesn't clip the same way at least when using one channel

I have this same amp for already two years in a half. It sounds good and hits bass nice. But the volume at half way it’s already limiting. I tried it at 4 ohms and 8 ohms . Still gets the limit light on. Full volume at 8 ohms stereo mode redlines but won’t shut down . It’s just crazy how the limit lights comes out so soon with out hurting the speaker or sounding loud.

Not sure if asked already. If I set this amp to bridged with a 16ohm load from two speakers/transducers wired is series the amp will run at its best?

@killcar5nbike2 Would you know the bias voltage of the mosfets I just did a repair replaced the mosfets and pwm IC’s and apparently I have to test the bias voltage of the mosfets even though they are the same mosfet make and model they only difference would be the batch number cheers Rick

Class D don't have output stage bias. They use a dead time that's controlled by associated components around/in the control IC. Whoever told you that is an arm chair technician.

Can anybody explain why several heaters are not used in direct parallel connection, stupid transformer makes no sense then, as if its easier to find such transformer compared to heaters. 2kw heater has impedance about 24 ohm, old school electric oven is even better about 7kw. Transformer creates more problems and limits.

Because the heater is from my bedroom and the transformer is one I had laying around that just made the heater an ideal load impedance. If I was doing lots of power tests on high power amps I'd make a proper load out of several heaters with series capacitors to cancel out the inductance to make the loads purely resistive.

@@MrSookonn I'm well aware speakers are a reactive load. For quantifiable results over repeat tests you need a purely resistive load. The transformer is only a purely inductive load when there is no load on the secondary. The heater is still a very near resistive load and it is easy to measure the power being dissipated in the load as it would be if the transformer were not there.

@@MrSookonn the transformers voltage rating for saturation is at 50hz and with no secondary load whilst flux density is at it's highest. Every octave increase in frequency increases saturation voltage by 6db. At 1khz that's 26db voltage that the transformer can take before saturation than at 50hz. The limiting factor is no longer core saturation but I2R dissipation in the windings.

Thanks for the video, do you think it is reasonable to work with two channels at the same time at 2ohm with a 300rms load?

This one's running 2.6 ohm on each channel. If your load is only rated for 300 Watts then you need to keep the volume level low to stop it being over powered.

so why is it a 8ohm rated amp if it does not like anything less than 16 ohm actually? also why does it have a bridging ability if it hates 4ohm cause we know 4=4ohm=8ohm load and most people bridge amps to run dual 18s and thus this amp will cook if you run it bridged so yeah...

It's rated 2 ohm per channel, or 4 ohm Bridge. An amp with a bridged load sees 1/2 the impedance, not double. Music isn't a constant amplitude sine, the average to peak ratio is significant. The amp can happily deliver short term transients without clipping but stay within its average power output.
