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.
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.
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.

These are superb little amps. Very small but pack some power. Great for an upgrade from stock radio to give better sound and more power.
Great little unit, fits nicely under the dash and provides a great punch to my music. This is no tube amp, but for the price, you get a decent quality sound. Most people wont need much more than this little unit.
considering that it is named Power Pack, this amp really deliver powerful sound as it is packed in a compact chassis, and even with its size it is still impressive and has exceeded my expectations
Installation was smooth, and it was also very easy to fit in due to its small size. Can power up my whole system and it surely sounded great.
Got this amp for my Subaru hatchback. Changed out the stock speakers with Alpine Type-Rs and Let me tell you, this little amp is nothing short of amazing. Packs a whole lot of sound in this tiny package. Alpine never disappoints with their killer products.
Tiny but powerful! It was an easy install, and its really pushing my JL Audio speakers cleanly with nice sound.
