Batboard

Wanted to add the siren/pa horn to my Astro Spectra.
I know I can use the Motorola TDN6251A with no problems except for space to mount it.

Can I use the Federal Signal MC 100 ?Is it compatiable with the AS series radios.

Thanks
Tim

Per Federal Signal the impedance of all there siren/pa speakers is 11 ohms so it should be good with the AS.
