In general amplifiers do not like driving low impedances. I'd fix the crossover to increase it a little. With passive xovers you sometimes have to sacrifice some sensitivity to make this happen.

The SB Satori tweeter is also a tweeter of low nominal impedance. If low impedance is a problem then you really need to go for an 8 ohm unit. Or a 4 ohm unit that needs resistive padding so you can increase the effective series resistance.

I know, but in my case it is impossible, only 4 ohm🙁
 
# output devices doesn't guarantee you are staying within their SOA. It is not wise to put 2ohm load on any mass market amplifier. You may have fried your Yamaha amp also. Measure the amp output for DC before you use it again.

Maybe you can redesign your crossover to make a more benign load? Or use autoformer to increase load impedance?
