How to use

Connect the speaker to the CB transceiver using the standard speaker output wiring, ensuring correct polarity where applicable. Mount the housing on a stable surface inside the vehicle or at the base station using suitable screws or brackets, taking care to avoid interference with vehicle controls or ventilation. Adjust the CB radio’s volume and squelch settings to achieve the desired listening level and clarity. Position the speaker for direct sound projection toward the operator for best intelligibility.

Usage recommendations

For optimal performance, place the speaker where it has an unobstructed acoustic path to the operator and secure all wiring connections to prevent rattles. Avoid mounting on thin panels that may vibrate; use solid mounting points or additional damping if necessary. Check the transceiver’s output level and adjust audio settings to prevent distortion at high volumes.
