Does anyone know where the speaker wires go on pcb galaxy 2-20 on manual I can only see one thanks
 
Would that be the aux or the bell + also the speaker doesn't have +\- does it matter thanks
 
I normally use the aux +12v, but it doesn't matter. The polarity doesn't matter on the speaker, as it's just a coil.
 
Do you know what connects to use for speech dailler it's a menvier sd1 on the optima I was using on pcb it has 3 pa-inturder-fire thanks
