  I recently installed your Roadanvi X12 unit in my 2019 Subaru WRX STI (non-Harman Kardon model) using the supplied DYX027 harness. While power, rear speakers, and most functions are working properly, I am not getting any sound from my front speakers.

  Can you please advise how I should properly connect the front speakers?

  Is there an updated or complete plug-and-play harness available that correctly wires all speaker outputs for Subaru models without the factory amplifier?

  Please go to DSP/DTS app to adjust to see how it work.
