Description

The Metra LOC-GMH3 is a vehicle-specific Active LOC T-harness designed to easily add a subwoofer or a complete audio system to your vehicle. It provides convenient access to speaker-level output signals from your factory radio. The harness offers signal connections for constant 12-volt (with a 10-amp fuse), ground, and remote turn-on leads. It simplifies the installation of devices like active signal processors by allowing the factory radio to remain fully connected while providing additional wires for aftermarket amplifiers.
