It changes the output of you headunit to flat clean signals.
So if you are upgrading sound system (Alpine kit or aftermarket), with coding head unit to hi-fi, your amplifier get cleans signals and thus cleans and less distorted sound output.
There is no point of having it done if one is not upgrading the sound system.
Hope that helps mate.
