Alpine, KTA-450
4-Channel Amplifier (main unit power pack) - Dynamic short-term power at 4 x 100W - at 2-Ohms
The KTA-450 is an extremely compact 4/2-channel amplifier designed primarily for use with the iLX-W650BT headunit, but can also be used separately with each universal installation.
Featuring the new Alpine Dynamic Short Term Power (DPP) technology , the KTA-450 is capable of producing 100W RMS of power in the short term when needed.
Together with the iLX-W650BT headunit , the KTA-450 won the 2019a Innovation Auginna CES Show 2019. If you are also planning to buy the iLX-W650BT , this tiny amplifier will make a big difference in your system.
