Alpine KTP-445A - Head Unit Power Pack

Quick Overview

Add higher output and more dynamic response with this easy-to-install head unit power upgrade. The KTP-445A amplifies the head unit power output, resulting in a 150 percent power increase over the original power from the head unit's built-in amplifier. The KTP-445A fits behind the head unit in the dash of most vehicles. Its plug-and-play installation keeps it simple, without requiring additional wiring or special tuning. The KTP-445A connects any 2005 and newer Alpine head unit that has a black power harness.
