How to make audio play when passes a collider

Hey sorry I didnt explain this right lol,

Cos i have a trigger but i need it to activate a sound when a Car goes over it cos i have cubes that can move everywhere but when they touch the trigger it activates the sound which i dont want i only want the Car to activate it

  var audio1 : AudioClip;
var audio2 : AudioClip;

function OnTriggerEnter (other : Collider) {
    if (other.gameObject.name == "Car"){
    audio.clip = audio1;
    audio.Play();
    }

    //Play another sound
    audio.clip = audio2;
    audio.Play();

}

You appear to have that second clip playing audio outside of the OnTriggerEnter event.

var audio1 : AudioClip

var audio2 : AudioClip;

function OnCollisionEnter (other : Collider) {

if (other.gameObject.name == "Car"){
audio.clip = audio1;
audio.Play();
}else{
audio.clip = audio2;
audio.Play();

}

if this help you rate it positive =D
