The GDS® Audio™ amplified speaker can be hardwired into the cab of your vehicle – with no batteries required for power. An adjustable knob allows for up to 93dB of amplified audio feedback from your device, and the speaker includes built-in overcurrent, short circuit, and overvoltage protection. As part of the GDS® Ecosystem™, the speaker can be mounted to any GDS® vehicle dock using the RAM® short bracket adapter or RAM® standard bracket adapter. Each bracket includes hardware to mount the speaker to the bracket, as well as the bracket to your GDS® vehicle dock.
