The KTA-450 4-Channel Power Pack Amplifier produces 400-watts of Alpine’s Exclusive Dynamic Peak Power for big subwoofer power in a small space.

With the highest performance value on the market, this mono-power amplifier provides an easy update path to add more bass to a sound system in vehicles that don't normally have the room for a traditional amplifier.

Utilizing Alpine's exclusive Dynamic Peak Power (DPP) technology, the 200-watt KTA-450M delivers bursts of power to meet the peak demands of music, effectively rising to 400-watts and then rolling back to maintain efficiency.

With the compact, Power Pack design, the amplifier can fit in hidden areas, like a glove box, under a seat, or mounted behind a receiver to optimize power and space in the vehicle.

The KTA-450M mounts behind the iLX-W760 7" Mech-Less Audio/Video Receiver with PowerStack™ technology.

When mounted to the iLX-W650, the KTA-450 is a CES 2019 Innovations Awards Winner.
