SoundXtreme ST-940BT Single DIN Digital Media Receiver

The SoundXtreme ST-940BT is a single-DIN digital media receiver for vehicles needing modern music playback and hands-free Bluetooth capability without a touchscreen head unit. It combines Bluetooth, USB, SD/TF card, AUX, and AM/FM radio sources in one compact dashboard receiver. This makes it a practical replacement for an older factory radio or a basic upgrade for a standard single-DIN opening.

Bluetooth connectivity lets a compatible phone stream audio wirelessly and supports hands-free calling through the receiver's built-in microphone. Front-panel controls provide access to playback, source selection, volume, radio tuning, and clock functions. A supplied wireless remote adds convenient control of common receiver functions from inside the vehicle.

The ST-940BT is rated for a maximum output of 60 watts across each of its four channels, or 240 watts maximum total. Its stereo speaker outputs support a conventional front-and-rear four-speaker vehicle layout. Rear RCA outputs also provide front and rear signal connections for use with compatible external amplifiers.

For stored music, the receiver supports MP3 and WMA playback from USB storage and SD or TF cards with capacities up to 32GB. A front 3.5mm AUX input accommodates portable devices that use an analog headphone-style audio connection. The source selection system also includes AM and FM radio listening, with automatic station storage capability.

This receiver fits into a straightforward audio upgrade path: use its internal four-channel amplification for a basic speaker system, or connect its RCA outputs to external amplification as system needs grow. It is intended for 12V negative-ground vehicle electrical systems and uses the included wiring harness for power, ground, speaker, and remote-turn-on connections. Installation keys, a remote control, and a user manual are included to support setup and everyday operation.

Design & Installation

The ST-940BT uses a compact single-DIN receiver layout with a central digital display, rotary power/mode/volume control, front USB connections, SD/TF card slot, front AUX input, and front-panel operating buttons. Product documentation does not specify the chassis or faceplate materials. The display shows operating status, time, radio frequency, and track information, while the IR sensor receives commands from the included remote.

Install the receiver in a standard single-DIN opening using a mounting sleeve, then connect the included harness according to the unit wiring diagram. It requires a 12V DC negative-ground vehicle system; connect constant power, accessory power, chassis ground, speaker leads, and the blue antenna/amplifier remote lead as applicable. Disconnect the vehicle battery before installation, verify all connections, and use the rear RCA outputs when adding compatible external amplification.
