CB Speakers & PA Horns

What You Should Know:

Use & Compatibility: Every CB radio on the market has a 3.5mm external speaker jack that allows you to play incoming transmission through an external speaker. This can be useful if you mount your CB radio in the dash Show More...
(causing the built-in speaker to be covered), or if you use your CB in a noisy environment and need additional volume or clarity. Certain CB radios also come with a public address (PA) mode, which lets you connect an externally mounted PA horn to your CB and use your microphone to broadcast your voice outside the vehicle.  

Wattage Limitations: Speakers and horns are both rated on the maximum wattage at which they can broadcast. The higher the wattage rating, the louder they will sound. Unfortunately, CB radios provide a maximum of 7 watts of power to the external speaker and PA. Regardless of the wattage rating of your speaker/horn, it won't be louder than 8 watts UNLESS you further amplify the signal. To overcome this bottleneck and generate more power, you'll need to purchase an amplified PA horn or speaker, or use an in-line CB speaker amplifier.
