Alpine KTA-450 - 4-channel amplifier digital, dockable

4-channel amplifier (head unit power pack)

The KTA-450 is a very compact 4/2-channel amplifier that was primarily developed for the power stacking system with the iLX-W650BT . However, it can also be used universally in many systems on its own.
With Alpine's DPP (Dynamic Peak Power) technology, the KTA-450 can deliver a peak output of 100 watts RMS power when required.
In combination with the iLX-W650BT , the KTA-450 was awarded the 2019 Innovation Award at the CES 2019 in Las Vegas. If you purchase an iLX-W650BT , this powerful amplifier can significantly enhance your system.
