Axxess LOC-NIH1 Active LOC T-Harness Nissan Infiniti Subaru

Add a Subwoofer or Full Amp System Without Cutting Factory Wiring — Axxess LOC-NIH1

Upgrading your Nissan, Infiniti, or Subaru audio system doesn't have to mean hacking up your factory wiring. The Axxess LOC-NIH1 is an active LOC T-harness engineered for non-amplified factory systems, letting you add a standalone subwoofer amplifier or a complete 4-channel audio system with a clean, plug-and-play installation. Your factory speakers keep working exactly as they should — no interruptions, no compromises.

Key Features

• Active LOC T-Harness: Mating 8-pin plugs stay connected during installation, ensuring factory speakers continue to receive power from the radio throughout the upgrade.
• Pre-Wired Subwoofer Output: Speaker-level audio output on the radio side of the LOC T-harness is ready for a dedicated subwoofer amplifier or powered subwoofer right out of the box.
• 4-Channel Amplifier Compatible: Wiring can be adjusted using the 8-pin connectors to integrate a full 4-channel amplifier into your factory system.
• Routes Amp Outputs Back Through Factory Wiring: Includes all materials needed to send your aftermarket amplifier's output back through the factory wiring to reach the speakers — keeping the install clean and hidden.
• Clearly Labeled Wire Bundle: Color-coded labels indicate exactly which wires to disconnect and where to connect your amplifier outputs — no guesswork.
