True.. I have a backup siren on my car. But the only manufacturer to give out a battery backup siren in the package right now is Viper. The rest it's an aftermarket add-on.
A real pain in the ass if I ever bring my car in to Charlie's or something... because if he has to do something which requires disconnecting the battery.... backup siren in that little garage can get annoying.
