I was looking into getting a car alarm with a remote starter, but I realize the alarm is only as good as the person who installs it. The last car alarm I had was just hanging and any theft could have disable it. I understand the basic of how an alarm, but I want to know what are some good qualities to keep in mind when searching for an alarm? What are some questions to ask when getting the alarm installed? There is one question I don't understand about an alarm. If the power to the alarm is cut off can you still turn on the car? If so what can you do differently?
