Alpine KTA-450

The KTA-450 is a very compact 4/2-channel amplifier that is primarily designed to be stacked with the iLX-W650BT, but it can also be used standalone in any universal configuration.

With Alpine's Dynamic Peak Power (DPP) technology, the KTA-450 can provide 100 Watts RMS power when needed.

Combined with the iLX-W650BT, the KTA-450 won the Innovations Award at the CES Show 2019. If you are planning to purchase an iLX-W650BT, this small amplifier will make a significant improvement to your system.
