It was a Viper Alarm, I honestly can't remember the model but it was one of the more expensive ones. If you want your car to stay put get a club, if you want to keep your system then I don't know what to tell you...
I've had cars stolen from me 3 times and broken into many many times. My subs and amps are bolted in my trunk, if theives want them they're going to have to spend 15-20 minutes getting them out. This sounds dumb but I've stopped locking my doors now, beats the hell out of picking up broken glass and then paying for a new window..
