Imho, Oscilloscopes are really only useful for making sure headunits don't clip at its max volume by checking the rca outputs. It shouldn't be used for amp gains.

Your midbass will always be the bottleneck of your system. They are usually the most inefficient, power hungry drivers in the system. It's limited in output by the excursion needs of the driver fighting the general hole around 60-80hz on the left side midbass. It's also useless in the 120-300hz range as there is always a big hole somewhere in there.

So with that in mind. Play music. Have your headunit maxed out. Turn off all other amp channels so only midbass are playing. Have crossovers turned on. Turn up your gains until your midbass distort or it gets too loud.

Stop. Set all other speakers in the car to match the midbass output.

I gotcha. Sometimes my friends turn the volume up past max and before I catch them, the mid bass just pounds so loud it sounds like the speakers are just gonna pop. I currently have the Morel Maximo Ultra MKII 602 and it’s range in Hz is 50-20,000, so should I use a 50 Hz test tone or somewhere in the 60-80 Hz range? Or should I use just music that I listen to frequently?
