Description
The remarkable KTA-450 Power Pack amplifier takes system expansion and power performance to new heights. Equipped with Alpine’s exclusive DPP (Dynamic Peak Power) technology that produces an impressive 400 watts ensures a solid boost of power during music peak transients and high output when it counts.
Whats more, the KTA-450 Power Pack amplifier perfectly pairs with the iLX-W650E 7” audio visual receiver (sold separately). By utilising the ultra-shallow chassis design of the head unit the amplifier mounts seamlessly onto the back of the chassis. This innovative space saving design, delivers incredible power output and dynamic sound—making the PowerStack duo an industry first and honored with the prestigious 2019 CES Innovation award.
