The CDE-172BT and UTE-73BT are compatible with Android AOA (Android Open Accessory) 2.0 for music control from an Android™ smartphone through the USB connection. The AOA connection delivers better sound and control over basic Bluetooth® audio streaming, and these functions are delivered through the faceplate keys on each model.
Both models are also “Made for iPod® and iPhone®.” Pandora® Music can be accessed from an iPhone® or Android™ phone. The models also have a new high-contrast, 1-line LCD display which delivers five times the contrast of conventional screens, for improved readability in the vehicle.
This one-stop music player has an LCD display with one-line, RGB illumination for your choice of display color. The new high-contrast LCD display has five times the contrast of a conventional screen, so the display is always easy to read.
Alpine's signature rotary knob makes controlling all your music a breeze. This unit also comes with a convenient front panel auxiliary input so you or your passenger can plug in a portable media player as an additional source.


The KTA-450 features Alpine’s exclusive Dynamic Peak Power (DPP). DPP intelligently adjusts the gain to adapt to musical needs.
DPP prevents the KTA-450 from clipping by supplying up to double the power for sudden, dynamic sounds. DPP ensures music sounds the way it should at high volumes and boosts the KTA-450 to 400 watts DPP, doubling its power without increasing its size.
Thanks to the efficient power needs of the DPP technology, the KTA-450 does not require a new power supply wire at the battery, so installation is fast using the supplied radio power wires.
In addition, the KTA-450 uses a 22-pin power harness with a recessed design on one side, so the cables can be tucked-in for a cleaner, less-bulky installation.
