Does setting like gain like this only work if the speakers have a higher rated RMS than the amp can put out? If they are below the amps and volume is increased on the head, won’t that cause damage to the speakers?

@STE6168 no. Distortion is what kills speakers, not power. You can run 1k watts to a 10 watt speaker, as long as it has a clean signal and you dont bottom out the driver. Essentially, you are setting the maximum clean volume. After that, you have to listen to your system. The speakers will let you know when it is too much- burning smell, popping, crunchy audio, etc. Regardless of the speakers and their power ratings, you always set your gains this way so that your signal is alwasy clean no matter how loud you turn it up, provided you don't exceed the head unit's max clean output.

When i check tha max outputs of my estéreo Kenwood exelon dmx 907s 😅 i used 1 kilohertz testtone and no distorted but when I set my gains of my amplifier dsp audiocontrol D-4.800 they shows distortion?????of my estéreo wy 😂😅 l

You always start at the signal source and then work your way to the amps. Is the dsp output is distorted, then you need to dial it down.

When setting the gain on the amp without the speakers connected does this mean the oscilloscope will be reading distortion at the stability of the amp? What i mean is if you going to use the same amp at 1ohm vs 2ohm will the clip point be the same?

Based on ohm load, the clipping point can change, occuring sooner than without a load. You can make (or buy) dummy loads for this type of test, which is a video I am working on. This would be a good real-world test to see just how much difference there is between unloaded, 4, 2, and 1 ohm loads. In most cases, I like to use the scope to determine the max clean input level from the source unit and any processors, then I set the base gain at the amp. For mids and highs, this is usually as far as it needs to go. For subs, you can tolarate a little more distortion (under 10%), but I prefer a zero-distorion system for SQ, so I will test everything with speakers connected and fine tune it. If you are running SPL or SQL, a lot of installers will build in a little distortion, specifically on the subs. for SPL, we often run square wave for competition, as square is louder due to the fact that the wave has no ramp-up/down, the peak of the wave is much longer than a sinusoidal (sine) wave.

Ground to negative speaker output, probe to positive.

Should I set my gains with my eq settings already set? Or set the eq settings after the gains. Also should the cross over be off or on HPF for fronts and rear speakers

You want the signal to be as you will use it, at least as close to what you can. Crossovers, eq, etc should all be set. That doesnt mean you can't adjust after, but the idea is to find the max clean volume and then don't go above that point. Some people tune in 5-10% distortion as it hard to hear, particularly in bass ranges, but that's a person preference. You can play with it, and once it starts making sense, you will figure out what you prefer.

Depends on if you are using the stock amp output. If you are running high-level input, then yes.
