The KTA-450 is a very compact 4/2-channel amplifier designed to be power-stacked with the Alpine iLX-W650BT but can also operate as a standalone amplifier in universal installations.

It features Alpine Dynamic Peak Power technology to add bursts of up to 100 Watts RMS per channel when required. The compact form factor simplifies installation in tight spaces and improves head unit driven systems when paired with compatible Alpine receivers.
