yea i got a viper 595 a few years ago when i was headin off to freshman year, i got the backup alarm (incase someone cuts my battery power it sirens for like 12 hours or something crazy) and a glass break sensor. the sensor is placed about where my right knee goes under the console and if i tap my keys on the window (any metal-glass contact) it will go off. vipers are the **** and they have so many options
Nice sounds like a good system I'll look into that one!
