I got this at a local shop thinking it was a pa speaker, but I can't get it to work. It has no markings and it has three wires red,white and yellow. If its a horn how do you connect it? Thanks!

 

I'm thinking it is a horn, as Pa's use a headphone type connector to connect to the CB.

 

That's what I'm thinking usually a pa speaker only has two wires.

 

Well actually now that I think about it my pa horn only has one 3.5mm plug.

 

Like a headphone jack? I had to install one on my old pa speaker.

 

This is a similar style to the one i bought a few years back.

 

that looks like a alarm siren.

 

It is possible to make a horn set up with it? Like have it's own button.

 

Yes. But I don't know if it has the horn sound.

 

Anyone? I bought this at an electronic store where all sales are final. I want to use it. Any ideas of how this thing can serve a purpose? Any reason why it wouldn't work as a PA?

 

Shouldnt matter whether its a PA or horn speaker. Either way its a loudspeaker. You just have to figure out what wires are what. I have a very similar speaker in the garage I can take a look at tomorrow. It has 3 wires but I forgot what each was for. I was originally using it as my PA until I got a smaller PA speaker.

 

Looks like an alarm siren.. i have the same thing just all black.. Grab a 12v drill battery and play with the wires.

 

like already said, thats an alarm siren. should be easy to get it to work since there are only 3 wires.

 

That's what I was thinking, alright thanks! Private message me tomorrow.

Do you use it as a pa?

If its sole purpose is siren, do you have a diagram of how to connect it to a button that would sound off the alarm?

 

its a siren I have damn near the exact same thing, 2 wires are a siren sound and one should be ground...wierd that theyre red white and yellow tho
