5-Watt External Speaker for MOTOTRBO Mobile Radios

The Motorola RSN4004A is a genuine 5-watt external loudspeaker designed to make incoming radio communications easier to hear in vehicles, offices and control-station environments.

By positioning radio audio closer to the operator, this compact speaker can improve clarity when the mobile radio’s built-in speaker is obstructed, mounted remotely or difficult to hear over surrounding noise.

Ideal for commercial fleets and professional radio installations, the RSN4004A provides a practical balance of clear audio output, compact size and flexible mounting.

Improved Radio Audio

The RSN4004A can make incoming radio traffic easier to understand when:

• The radio is mounted under the dashboard

• The internal speaker faces away from the operator

• The radio body is installed remotely

• Vehicle or equipment noise reduces intelligibility

• A control station requires better speaker placement

• The operator needs audio directed toward a specific position

Actual volume and audio quality depend on the connected radio, volume setting, installation location and surrounding noise level.

Compatible Radio Families

The RSN4004A 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.

Compact 5-Watt Design

The 5-watt output makes the RSN4004A well suited for applications that need clearer, better-positioned radio audio without the additional size or output of a higher-powered speaker.

For louder environments, compatible 7.5-watt or 13-watt Motorola external speakers may be more appropriate.

Important Product Distinction

The RSN4004A is intended to reproduce 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 adequate clearance for the speaker and bracket

Professional installation is recommended.
