J&M JMCB-2003B-DU CB/Stereo/Intercom for Driver Headset Operation Audio System

- Audio performance is superb, even at high speeds and that is most impressive considering it's compact size

Note: The JMCB-2003 is a J&M 6-pin audio system that requires the pre-amplified microphone signal provided by Dual Mode (ECD/ICD/BCD/CD prefixed) helmet headsets along with the #HC-ZIM or #HC-PJM lower-section hook-up cord
