Alpine KTP-445A Power Pack -Compact Upgrade Amplifier for Your Alpine Receiver.  45 watts RMS x 4.   The KTP-445A Power Pack amplifies power output on select 2005 and newer Alpine head units, resulting in up to a 150 percent power increase over the original power from the head unit's built-in amplifier.




Compact size lets the KTP-445A fit where most amplifiers won’t. The KTP-445A comes equipped with direct plug-in connectors for select 2005 and newer Alpine head units and it fits behind the dash of most vehicles. It's small and compact at only 7-7/16” x 1-1/2” x 2-1/2”. Its size and flexible wires make the Power Pack an easy choice to save space.




In order to ensure that Alpine sound quality is heard, we’ve created a platform that offers an unbelievably low noise floor, taking extra care to ensure a clean signal path, with no extraneous interference. The end result: The Power Pack boasts 1 Watt Signal-to-Noise Ratio of 82dB or better.
