Alpine KT-445A is a powerful amplifier designed specifically for use with Alpine head units from 2005 onwards. With its impressive specifications and easy plug and play installation, it is the ideal solution for maximizing your vehicle's sound potential.

With a maximum output power of 4 x 100 W and an RMS power of 4 x 45 W, the KT-445A delivers powerful sound reproduction that takes your listening experience to a new level. Whether you want to listen to your favorite music or add enhanced sound to your vehicle, this amplifier offers the power you need.

Installing the Alpine KT-445A couldn't be easier. Thanks to the direct plug connections, no complex wiring is required. The amplifier can be connected directly to Alpine car radios from 2005 using a black Molex connector. In addition, it is so compact that it fits directly behind the dashboard in many vehicles. With dimensions of just 177 mm x 35 mm x 66 mm (W x H x D), it can be easily integrated into tight installation locations without sacrificing performance or sound quality.

The Alpine KT-445A is characterized by its outstanding signal-to-noise ratio, which is 82 dB (1 W) or better in its class. This achieves an incredibly low noise floor, which significantly improves the sound quality. Even at high volumes, the sound remains clear and detailed.

Another notable feature of the KT-445A is its low total harmonic distortion (THD + N) to frequency. Unlike many other amplifiers, distortion actually decreases at higher frequencies, resulting in a clean and clear signal. With a THD+N of less than 0.03% at 1W and 1% at rated power, this amplifier delivers impressive sound quality across the entire frequency range.

The Alpine KT-445A is the perfect choice for anyone looking to upgrade their Alpine head unit with a powerful and easy-to-install amplifier. It offers premium audio performance, installation flexibility and the trusted quality of the Alpine brand. Enjoy an impressive sound experience on your rides with the Alpine KT-445A.
