This compact and efficient amplifier is designed to give your car audio a significant boost, ensuring you can enjoy your favorite music with greater clarity and power. Say goodbye to lackluster sound and experience an audio upgrade like never before.

Small Size, Big Impact

The Alpine KTP-445U is specifically engineered to fit in places where most amplifiers can't. With its small and compact dimensions of 7-7/16” x 1-1/2” x 2-1/2”, this power pack can easily slide behind the head unit in the dash of most vehicles. Its size and flexible wires make it an ideal space-saving choice for your car audio setup. Despite its small form factor, this amplifier packs a punch that will transform your audio experience.

More Power, Less Hassle

Looking to crank up the power of your car receiver without a complicated installation process? The Alpine KTP-445U is the answer. It increases your receiver's power output to 45 watts RMS by 4 channels, a significant improvement from the 7-20 watts per channel typically produced by a car radio. This amplified power is more than enough to drive high-performance speakers or complement a big subwoofer amplifier. The best part? This compact amplifier is incredibly efficient, allowing you to run it off the same circuit that powers your receiver. No need for complex wiring or additional power sources. The universal plug lets you easily feed a signal via RCA outputs or speaker-level wiring, making the installation a breeze.

Versatile Input Options

The Alpine KTP-445U Power Pack comes with independent filters for rear and front inputs, providing frequency filtering options for a wide variety of speakers. Whether you prefer full range or selectable range options like 60Hz, 80Hz, or 120Hz, you can fine-tune your crossover points to suit your audio preferences. Moreover, the bottom panel of the Power Pack offers selectable input options to accommodate Speaker-Level (0.5V-10V) or RCA (0.2V – 4V) inputs. The selectable 2 Channel and 4 Channel options give you control over your source inputs, eliminating the need for Y-adapters. These configurable inputs ensure seamless integration with your car audio system.

Simple and Accessible Controls

When it comes to adjustments, the KTP-445U Power Pack keeps things simple and accessible. It provides variable gain controls on the end panel, allowing you to fine-tune the settings based on your specific system requirements. Whether you want to push the volume to the max or dial it back for a more laid-back listening experience, the choice is yours.

Unbeatable Sound Quality

Alpine is renowned for its exceptional sound quality, and the KTP-445U Power Pack is no exception. Designed with a low noise floor, this amplifier ensures a clean signal path with minimal interference, delivering the purest audio to your ears. The Power Pack boasts an impressive 1 Watt Signal-to-Noise Ratio of 82dB or better, ensuring that every note and beat reaches your ears with unmatched clarity. Furthermore, the Total Harmonic Distortion (THD+N) is exceptionally low, measuring less than 0.03% THD+N at 1W and 1% THD+N at rated power. This means that even at higher frequencies, where distortion is most noticeable, the KTP-445U delivers a clean and clear signal that stays true to the original audio.

Installation and Compatibility

Installing the Alpine KTP-445U Power Pack is a straightforward process. It can be installed behind most dashboards, but you will need 4-channel patch cables to connect your car stereo to the amp's preamp inputs. Alternatively, you can splice into your speaker wiring to get a signal to the KTP-445U. Please note that for optimal performance, we recommend running a dedicated constant power wire to the battery. This will ensure that the amplifier operates at its full potential. The KTP-445U Universal Power Pack is compatible with both aftermarket and factory-installed head units, providing up to a 150 percent power increase over the original power from the head unit's built-in amplifier.
