The KTP-445a connects any 2005 and newer Alpine head unit that has a black power harness.

The KTP-445a fits behind the head unit in the dash of most vehicles. It’s small and compact at only 7” x 2-1/2” x 3/8”. Its plug-and-play installation keeps it simple, without requiring additional wiring or special tuning. A high/low gain switch allows for proper gain settings, whether or not a subwoofer is part of the system.
