Alpine UTE-63BT is a shallow-chassis single-DIN Bluetooth® digital media receiver designed for easy fitment, everyday wireless connectivity, and practical sound tuning. Its 4.25-inch mounting depth helps it fit in vehicles with limited dash space, while Bluetooth® hands-free calling and audio streaming, AM/FM with RBDS, and a front USB port cover the core daily-use sources. The receiver also includes an external microphone for clearer calling. The UTE-63BT is built with an 18W RMS x 4 amplifier, three 2V pre-outs for front, rear, and subwoofer channels, and Alpine tuning features including a 3-band parametric EQ, high-pass and low-pass filters, Bass Engine SQ, and a 24-bit DAC. A 1-line high-contrast LCD with RGB illumination keeps the interface simple, while Android™ compatibility, Pandora® Music support, and steering wheel control compatibility add practical upgrade flexibility.
