stupid panic button

I sitting here at the comp. and I hear my horn blowing. I look out and there is nothing wrong exept my horn is going off. I go get my keys and hit the panic button to turn it off it turns it off but I don't want it to do this through the middle of the night or when I'm not at home. Neighbors might not be to happy. I have no idea why it would do this. How can I disable the panic mode on the car? It is a 2004 cav. Thanks Oh wait it's doing it again it's been a whole 5 minutes.

It's a 2004...take it to a dealer under warranty.

The only problem with that I just had installed an entire stereo sysyem in the car On friday.

Irrelevant. Take it there and tell them you want them to fix it. If they determine the problem to be the stereo, take it to where you got the stereo installed.

If you fix it yourself, you MIGHT break it, and it's better to let someone else break it.

and you didnt make any connections between installing the system and the panic going off?
