Alpine KTA-450 4-Channel Power Pack Amplifier

The next generation of Power Pack is here, featuring the compact KTA-450 Power Pack Amplifier. This unit utilizes Alpine’s exclusive Dynamic Peak Power (DPP) technology to deliver a significant power boost within a remarkably small footprint.

Designed for versatile installation, the KTA-450 measures just 17.8 cm W x 8.9 cm H x 3.2 cm D, making it ideal for tight spaces like glove boxes or behind the radio. Its PowerStack capability allows for seamless mounting to select 2-DIN head units, such as the iLX-W650, using the included bracket for a clean, integrated setup.
