Whelen speaker for 2011 Crown Vic?

I recently picked up a 2011 Crown Vic Interceptor. I absolutely LOVE the car so I have been adding fun things to it.

One of my techs @ the motorcycle shop I work @ found me a Whelen siren off an old police bike we worked on. The speaker does work but I need a PA to hook it up to I think? I am new to this so bear with me if I don't quite understand what I need to purchase. Links would be appreciated.. I did some reading and read it is more for sirens than any other sounds and that is fine I just want it to play with.

Help! TIA!
