Product Description
This car speaker amplifier with an integrated decoder processes audio files directly in the vehicle, without the need to connect external playback devices. The module decodes MP3 and WAV formats and drives speakers directly, reducing the space required in the vehicle.
Power is supplied by the vehicle's 12 V electrical system. With up to 2*10 W output power, the module is sufficient for mid-range vehicles and simple installations; an external power amplifier is required for higher demands. Operation is controlled by three buttons for playback, volume, and track changes.
Audio sources are memory cards (SD, microSD) or USB connections. Mono or stereo output can be selected depending on the vehicle configuration. The module fits standard compartment applications and does not require a separate power supply system in addition to the vehicle's electrical system.
Installation is limited to vehicles with a 12 V electrical system; consult the manufacturer regarding 24 V systems. Vehicles with factory-installed safety wiring or active antenna systems may require additional level converters or isolators. MP3 and WAV files must be transferred to the memory card or USB flash drive before use; file management on the module itself is limited to the three buttons.
Safety Information
This module is not intended for connection to household electrical installations and is exclusively intended for constructing vehicle audio prototypes and for testing and development purposes. Work on or near vehicle electronics must be carried out by qualified electricians; if in doubt, consult a qualified electrician before commissioning. Ensure correct polarity when connecting the power supply; reverse polarity will damage the module.
