But that 1.25 amps is using the speaker with the built in amplifier/siren driver, right? I think most of us are just using the speaker for audio purposes and with the built-in siren amp.Spanky said:On an eight ohm speaker running 12 VDC driving the siren amplifier you could be running 1.25 amps through the wires. I like to use 18 guage minimum, 14 to 16 on long audio runs. You will loose some audio on long wire runs.
Temporarily I plan on having an output from the M1 trigger a siren in my intercom. Not exactly what the NFPA would call Kosher
