I had an annoying neighbor in College and I used a tweeter and 14,100 =
Hz....man that will give you a headache!!!  Maybe not great for a car =
alarm because it took awhile to figure out it was caused by sound and not =
your own ears ringing.  I left when I turned it on...:)

I asked the list about this last year. End result was a smoke
generator + horn to attract attention if the car's driven and an
indelible ink sprayer + piezo bomb in the dashboard. Green
