I have heard this story some several sources.... An E.E., who hates loud music,
builds a device that can cause a stereo system to self destruct. When teens
pull alongside his car with their subwoofers kickin', all it takes is a push of
a button, and the sonic pollution is stifled....

My question is, is this a B.S. urban legend or not?

I would think that, since many power amps are designed with a wide bandwidth,
all it would take is a sufficiently strong ultrasonic signal to overload the
amp... which begs the question, how would one inject souch a signal into a
stereo system 10 feet away from you...

Just something to ponder over.
