Yeah i too thought of a siren inside, espeically if it was mounted in a tamper proof case with the wires sealed in either conduit or inconviently hidden behind molding. The perfect position would be mounted directly behind the driver seat on the pillar between the driver window and the back window. F-em up real good...
Off the subject I was curious what companies make dependable alarms with remote warnings whenever the alarm is triggered? Churppers i think there are called.
Yeah idk about good citizens anymore especially when a car alarm is going off, I guess society is just used to so many people accidently sounding there alarm there dont even pay attention.
