SoundXtreme ST-900BT Bluetooth Digital Media Receiver

The SoundXtreme ST-900BT is a Bluetooth digital media receiver designed to add modern music playback and hands-free calling to a vehicle audio system. It provides several listening options in one compact head-unit format, including Bluetooth streaming, USB media, SD card playback, and an auxiliary input. This makes it a practical choice for drivers who use phone-based music or stored digital files rather than CDs.

Bluetooth connectivity allows a compatible phone to stream audio wirelessly and handle calls through the receiver’s hands-free function. The unit is intended for everyday commuting, work vehicles, and simple audio-system refreshes where convenient source selection is the priority. Its built-in microphone supports phone conversations without needing to hold the phone while driving.

The ST-900BT is rated at 60 watts per channel across four channels, for a listed total of 240 watts. That output is intended to power a conventional four-speaker vehicle setup directly from the receiver. For installations requiring substantially higher volume or dedicated subwoofer power, an external amplifier may still be appropriate.

For local media libraries, the receiver supports USB drives and SD cards with capacities up to 32GB. It is listed as compatible with MP3 and WMA audio files, allowing music to be carried without relying on a mobile-data connection. The auxiliary input also provides a wired option for compatible portable media devices.

A digital display, front-panel controls, and included wireless remote provide straightforward operation from the driver or passenger seat. The ST-900BT can serve as the central source unit in a basic replacement stereo installation with compatible vehicle wiring and speakers. Because vehicle dash openings, harnesses, and antenna connections vary, installation accessories should be selected for the specific vehicle.

Design & Installation

Available product information confirms the display and remote-control functionality, while specific cabinet materials, display dimensions, and illumination details are not published. Its design is focused on digital-media operation rather than disc playback.

Install the receiver using vehicle-appropriate mounting hardware, a compatible wiring harness, and an antenna adapter where required. Connect it to a properly wired 12-volt vehicle audio system and compatible speakers before use. Confirm the dash opening, connector arrangement, speaker wiring, and available installation depth for the vehicle before purchase.
