This LOC T-harness is equipped with mating 8-pin plugs that remain connected when installers are adding a subwoofer amplifier, ensuring that the factory speakers continue to receiv e power from the radio. On the radio side of the T-harness, there is a pre-wired speaker-level audio output for a dedicated subwoofer amplifier or powered subwoofer, making the installation highly versatile and compatible with various setups. To power your aftermarket system, the wiring can be adjusted using the 8-pin connectors and harnesses for integrating a 4-channel amplifier. This T-harness includes the materials needed for routing the outputs of your aftermarket amplifier back through the factory wiring to reach the speakers. Clearly marked labels on the wire bundle indicate which wires to disconnect and where to do so, as well as which wires should be connected to the outputs of your aftermarket amplifier.
