SoundXtreme ST-950BT Digital Media Receiver

The SoundXtreme ST-950BT is a digital media receiver designed to add modern music playback and Bluetooth calling capability to a vehicle audio system. It provides FM radio, Bluetooth audio, USB, SD card, and front AUX playback in one compact head-unit format. It is suited to drivers who want multiple source options without a CD mechanism.

Bluetooth connectivity allows compatible phones to stream audio wirelessly and handle hands-free calls through the receiver's built-in front-panel microphone. The receiver identifies itself as ST-950BT during pairing, with a documented pairing code of 0000 when requested. Front-panel controls and the included remote provide access to source selection, volume, track functions, and radio operation.

For local media playback, the ST-950BT supports MP3 and WMA files from USB storage devices and SD cards. Supported USB drives and SD cards can be up to 32GB. A 3.5mm front AUX input also accommodates a wired portable music player or phone audio adapter.

The receiver is rated for a maximum output of 60W across each of its four channels. Its FM tuner provides FM1, FM2, and FM3 bands, with six numbered preset buttons and automatic memory-store functionality. Rear RCA outputs are provided for connection to an external amplifier.

The ST-950BT can serve as a straightforward replacement receiver in a basic vehicle audio upgrade. Its supplied wiring harness supports constant 12V, switched 12V, chassis ground, power-antenna or amplifier remote turn-on, and four speaker connections. Installation keys, a remote control, and a user manual are included to support installation and daily use.

Design & Installation

The ST-950BT uses a digital front display, a multifunction power/mode/volume knob, numbered preset keys, a front USB port, a front 3.5mm AUX input, and a front SD card slot. A built-in microphone supports Bluetooth calling, while an IR sensor receives commands from the included wireless remote. The supplied installation keys and trim-ring mounting approach support serviceable in-dash installation.

Connect the yellow lead to constant 12V power, the red lead to switched ACC power, and the black lead to vehicle chassis ground. The blue lead is designated for a power antenna or amplifier remote turn-on, while the harness includes separate positive and negative leads for front and rear speakers. Confirm vehicle fitment, connector needs, speaker wiring polarity, and fuse requirements before installation; professional installation is appropriate when vehicle wiring is uncertain.
