SoundOff dual tone w/ PowerCall?

[kadetklapp]

We run SoundOff systems in our three PD vehicles. We are in the process of having a vehicle built and I have always wanted a PowerCall-sounding siren. With all of our vehicles, we run dual speakers with dual tones. I was wondering if there was a possibility of getting a PowerCall-esque Wail and Yelp fed into the second speaker. I don't have any clue if this is just an idiot thing to do, or if it would require two completely separate siren systems?

I’m not familiar with the SoundOff options, but Whelen has dual tone sirens with what they call “whoop” and “warble,” which are Powercall type sounds. You could also use a Sho-Me 30.2220 as a secondary amp.
