how can i make a samurai sword with a saw and metal file
From reading your question, it's obvious you really don't want an answer. I don't care what you put on the car, if some wants your stereo, it will be gone. So, if you are dumb enough to make your car that big of a target do two things. 1. Put on the best alarm you can, preferably one that will page you when it goes off. 2. Add an umbrella coverage to your insurance to cover the stereo when it does get stolen. As an aside, they will probably take your whole car away and remove the stereo at their leisure, so make sure you have theft coverage on the vehicle also.
if it is a rental unit there has to be smoke detectors, if it is your house it is up to you
