How can i choose what channel to play my audio by myself?

I have some audio sources in my game, and I set them as 3D Sounds.
Then I set my AudioSpeakerMode to Quad.
But in some special cases, i want to play some specific audio sources in specific channels not in all channels at the same time.
for example, i just want to hear the music in my front left channel, can i do that?
Can someone give me a hand, please?

Try experimenting with a audio source that is child to and position to the left (or right) of the audio listener. Then play the audio clip for said audio source.
