Hello…new member here. Have a question for the forum. I have a 295SLSA6 controller with an SA315P speaker. I’m using it in my personal vehicle. I’m using it for the PA, air horn, and auxiliary switches. Not using it for a light at or siren. Don’t want it connected into my horn either. So I’ve got everything connected I need, I believe. So when I connected the speaker to the unit, I get nothing! No PA or horn. But controller backlight lights up, and slide switch and buttons all work. And yes, I did have the switch on. Have rotary knob set to MAN 1. The wires I have connected to the speaker are the yellow and brown. Am I missing a connection somewhere? Or does the wire gauge from the speaker make a difference? I’m hoping someone here can help! Thanks!!
