ALPINE KTA-450 - 4-channel amplifier 4 x 100W

The KTA-450 is a very compact 4/2-Channel amplifier, that is mainly designed to be power-stacked with the iLX-W650BT, but can also be used stand-alone in any universal configuration.

Featuring Alpine’s Dynamic Peak Power (DPP) technology, the KTA-450 can add bursts of 100 Watts RMS power when needed.

In combination with the iLX-W650BT, the KTA-450 won the 2019 Innovations Award at CES Show 2019. If you plan to buy an iLX-W650BT, this tiny amplifier will make a significant improvement to your system.
