Just ran across these: Mini Transducer Array with Enclosure

With a little work, and an Arduino, you can create a replica of the LRAD. If someone were to array three or four of these behind your grill, could we use them as an ultra 150DB or louder car horn?

The reason an LRAD would be preferable would be to focus and aim the sound directly into the space in front of the car, making it able to penetrate even an SUV or Semi.
