Alarm Sirens???
 

Im looking for the biggest and Loud Alarm Siren is... and no Im not lookin for a fog horn....:P

Any Ideas if there any thing like that or even illegal i dont care i want to beef up my alarm now...

I find it easier to just add more sirens, hooked up with relays, and you can't forget small piezo sirens for in cab use... I don't know anyone willing to steal a stereo with a few of those babies going off.. they are f'ing loud.
