Federal signal AS-124 setup

So I got my first siren today completely by random. A very stripped crown vic at the local LKQ junkyard had a Federal Signal AS-124 100W speaker on it. I connected it directly to my Nokia 7.1 and it did work but very quietly. However, the Vic was completely stripped inside and had all of the wires chopped. I couldn't find an amplifier or a microphone. It also must have been an undercover car, as it had no lights save for the manual spotlight. The yard had no idea what to price it at. I offered $10. $10 later and I had a Federal Signal.

My question is what controller/ amplifier system would be designed to go with this thing? Also, Would any 12V auto amplifier work or would it blow up?

They are 11 ohm speakers and are not designed for a normal audio amp. You need a 100w or 200w electronic police siren, even if it's just a cheap Chinese knockoff.

Turns out this speaker pairs nicely with a Whelen 295HFSA1. I got it out of an ambulance at a northern KY pulling yard for free since the microphone was missing.
