Alpine KTA-450: 4-Channel Power Pack Amplifier

The KTA-450 4-Channel Power Pack Amplifier produces 400 W of Alpine's exclusive dynamic peak for big subwoofer Power in a small space.

Through 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 W KTA-450M delivers bursts of Power to meet the peak demands of music, effectively rising to 400 W and then rolling back to maintain efficiency.

Through 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" mechless audio / video receiver through Powerstack technology.

When mounted to the ILX-W650, the KTA-450 is a CES 2019 innovations awards winner.
