i have a 2012 toyota tundra and i was wondering a website that would sell a PA system that i could use to talk on so people outside of my truck can hear me ( like how a police vehicle)

any help for this would be great, thank you.

steal one from the police!

although this is high on the list of the things i should do . i probually shouldn't do that, any other suggestions or anyone know?
