I had a feeling you got it installed at a chain store I had mine done at Circuit City and the thief who stole my car got it in like 30-45 seconds, cause both the siren and the brain of the alarm were easily accessible, needless to say, I won't be taking my car there for an alarm install anytime soon. A quality install will include hiding the siren and brain, so if you do decide to just get another siren and call it a day, make sure the siren isn't in plain view under the hood
