External CB Speaker For In The Cab Use. Adjustable Talk-Back feature, noise filter switch.
This top of the line CB speaker is designed to give you loud, clear audio, and also comes with a Talkback function that allows you to hear your voice during transmissions. This can be a useful tool to make sure your radio is functioning correctly, if you hear your voice there is a good chance you are transmitting. The black wire is for the standard external speaker function, the red wire would need to be plugged into a PA speaker jack. If you're radio doesn't come with a PA speaker jack you won't be able to hear the talkback function.
