Hi Akash, welcome to Arylic Forum.
The crossover is not showing in the normal way because of the tool. But, we apply different filters on the output. Normally, we use a high pass filter for the Left/Right channel which is the major stereo output, and use a low pass filter for the Mono channel which is normally used as the subwoofer output. and you could use different frequency for the filters.
And a audio path picture to help understand how the audio flows, the blue blocks could be adjusted in ACP tool.
