Stereo & Electronics - Can I add a siren?

My ,99 T/A factory alarm only honks it's horn...can a siren be added?Is there a better alarm out there that will work in tandem with the BCM?

No, you can't just add a siren because the factory alarm uses a pulsed output to honk the horn but a siren requires a continuous output. You can add a Hornet 700T alarm upgrade (made by DEI) to the stock system for about $75. It will give you a siren, a new shock sensor, and the ability to add additional sensors such as a perimeter sensor or a glass shatter sensor. With the exception of the siren and the power/ground connections, all the wires can be connected at the BCM so installation is easy. Also, it still uses your factory remote key fobs.

Thanks, Whitebird00 I'll look into that. My son,who says I'm being paranoid,suggested louder horns, which may accomplish the same thing.
