  • Add an after-market speaker amplifier and/or subwoofer to your factory head unit

  • Install a Line Output Converter, audio processor (LC6i, re-Q, 3sixty.2, CleanSweep, MS-8, bit one), etc.

  • Install a car phone kit, gauges, or any other accessory that you need to connect between the car's factory harness and OEM radio

  • Defeat in-motion lockouts present on many factory HUs

  • Do all of these without cutting your factory wires

Use this harness when you are keeping the factory radio in your Subaru or Nissan and want to add something in between the radio and the car.  This combined harness will save you time and effort.  All 20 pins are already connected straight through.  All four speaker channels (8 wires) are longer, ready for you to cut or tap in the middles and connect to your speaker amplifier, Line Output Converter (LOC), audio processor, or other aftermarket gear.

The ground and two +12V power wires already have "T" branches connected.  You can use the Red +12V Accessory line for an amplifier remote turn-on (since most Subaru factory radios don't have that signal).

Wires have the EIA-standard color-coding used by after-market car audio equipment, with printed labels (for example, "LEFT FRONT POSITIVE").

Wires include:

  • Four speakers (8 wires)
  • Ground with "T" branch
  • +12 Volt Accessory (key-switched) with "T" branch
  • +12 Volt Battery (always-on) with "T" branch
  • Power antenna control (power for antenna booster amplifier or remote trigger for motorized antenna)
  • Illumination ("Illumination +")
  • Dimmer ("Illumination -")
  • Audio Steering Wheel Controls (2 or 3 wires)
  • CAN data bus (2 wires) and/or additional signals used on some models

Fits all Subaru and Nissan models that can use Metra 70-7552 and 71-7552, Scosche NN04B and NN04RB, American International NWH-704, Aerpro APP091, etc., including:
