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

4-channel amplifier (head unit power pack)

The KTA-450 is a very compact 4/2-channel amplifier that is mainly used for the< nonbreakingspace/>Power Stacking System with which iLX-W650BT was developed. However, it can also be used independently in many systems.

With  DPP technology (Dynamic Peak Power) from Alpine, the KTA -450 deliver a peak power of 100 watts RMS power when needed.

In combination with the iLX-W650BTthe KTA-450 was awarded the Innovation Award 2019 at  CES 2019 in Las Vegas . If you purchase a iLX-W650BT this powerful amplifier can add significant value to your system.
