Instead of installing an expensive car alarm system or using ineffective methods to prevent your car from getting stolen, learn how to install an inexpensive, hidden kill switch. http://simplisafe.com/dreamcar This kill switch is easy to install and anyone can do it at home with basic tools. It can also work along with your car's current alarm system. How it works is it cuts the power to the fuel pump so you cannot jump start the car, hot wire it, or even push start it. In order to steal the car you need to tow it! It is better than a batter quick disconnect because your computer wont restart and you wont lose your radio stations.
