Record speakers

Hello Next week my Rainbow SLX 265 deluxe will come. You should record the loudspeakers. But since I hardly drive during the week and am currently not on the road at the weekend, I would like to record the loudspeakers at the home system. The amplifier is a Pioneer SX 304RDS with 290 W and 8 Ohm. Can I connect the Rainbow there and if so how do I play it properly? Can I hang the loudspeakers normally on the crossover and then on the amplifier? Do the sounds have to be How and how long do I have to play it? So howvie operating hours. How loud? Certain music? Greetings Mathias
