7.5-Watt External Speaker for MOTOTRBO Mobile Radios

The Motorola RSN4003A is a genuine 7.5-watt external speaker designed to make incoming radio communications louder and easier to understand in vehicles, control stations and noisy work environments.

By positioning radio audio closer to the operator, it can improve intelligibility when the mobile radio’s internal speaker is obstructed, mounted remotely or unable to overcome surrounding equipment and road noise.

With more output than the compact 5-watt model, the RSN4003A provides a strong balance of audio performance, manageable size and installation flexibility for professional communications systems.

Key Features

• Provides up to 7.5 watts of external radio audio

• Improves the audibility of incoming communications

• Helps overcome road, engine and equipment noise

• Allows audio to be positioned closer to the operator

• Useful when the radio’s internal speaker is obstructed

• Suitable for mobile and control-station installations

• Designed for select Motorola mobile radios

• Genuine Motorola Solutions accessory

Improved Radio Audio

The RSN4003A can improve incoming radio-audio performance when:

• The radio is mounted beneath the dashboard

• The internal speaker faces away from the operator

• The radio transceiver is installed remotely

• Vehicle or machinery noise reduces intelligibility

• A control station requires better speaker placement

• Audio must be directed toward a specific operating position

Actual volume and clarity depend on the connected radio, volume setting, speaker placement and surrounding noise level.

Compatible Radio Families

The RSN4003A is designed for select Motorola mobile-radio families, including compatible models from the:

• MOTOTRBO XPR 4000 Series

• MOTOTRBO XPR 5000 Series

• MOTOTRBO XPR 5000e Series

• MOTOTRBO DM3000 Series

• MOTOTRBO DM4000 Series

• MOTOTRBO DM4000e Series

• Corresponding DGM and XiR mobile-radio families

Compatibility varies by radio model, connector and installation configuration. Confirm compatibility before ordering.

7.5-Watt Audio Output

The RSN4003A provides more audio output than the Motorola RSN4004A 5-watt speaker, making it better suited for moderately noisy vehicles and workspaces.

For extremely loud environments, a compatible Motorola 13-watt external speaker may provide stronger output.

Speaker Comparison

• RSN4004A: 5-watt output for compact installations and moderate audio needs

• RSN4003A: 7.5-watt output for increased volume in noisier environments

• RSN4002A: 13-watt output for demanding high-noise applications

Radio compatibility should be confirmed before selecting a replacement or higher-output speaker.

Important Product Distinction

The RSN4003A reproduces received radio audio. It is not a public-address horn, siren speaker or independently powered audio amplifier.

The connected radio must support the speaker’s electrical and connector requirements.

Installation Information

Install the speaker where it:

• Directs audio toward the operator

• Does not block vehicle controls or visibility

• Remains protected from excessive moisture

• Does not interfere with airbags

• Allows safe cable routing

• Has sufficient clearance for the speaker and mounting bracket

Professional installation is recommended.
