Disabling audio Listener on the child of a newly instantiated gameObject?

I am making a multi player game, but my problem is when the character is instantiated it has its own audio listener, what Im planning to do is have it disabled by default and when it is instantiated enable the audio listener so only your's will have an audio listener, but I don't know how to enable the audio listener because its a child of the instantiated object, any ideas would be really helpful PLEASE.
