Power Pack Series Car Amplifier
With Alpine's Power Pack car amplifiers, you get a louder audio output compared to what built-in amplifiers from car receivers can offer you, and a great example of that is the KTP-445U. This compact amplifier can give you more power than you'd ever expect.

Class D Amplifier
Thanks to its Class-D amplifier design, the Alpine KTP-445U can deliver 45 Watts of RMS Power at 4 or 2 ohms and 90 Watts of continuous power output at 4 ohms when setting the amplifier on a bridge mode. It has a signal-to-noise ratio rate of 82 dB, which means that it has minimal noise when you use the amplifier at high volume levels.

Variable High-Pass Filter
It has a variable high-pass filter to filter out unwanted frequencies that can affect the quality of your audio output. Whether you set the Alpine KTP-445U at full-range or want to cut all frequencies below 60, 80, or 120 Hz, you get a more defined audio quality performance from the amplifier. You can also set it in a two or four-channel mode, depending on what your car's speaker system needs.
