  1. Disconnect the negative battery terminal to avoid any electrical mishaps.
  2. Remove the old head unit and disconnect its wiring harness.
  3. Connect the new head unit’s wiring harness to the car’s wiring harness using a wiring diagram to ensure you connect the correct wires.

  5. Connect the amplifier to the head unit using RCA cables.
