Hello, Members.

My 2015 STi came with Fujiten head unit and Harman Kardon speaker and amplifier.
Without having professional knowledge, I D.I.Y the wiring and have been using the audio with XAV-AX100

Now, I just realize that Audio is played without going through the Harman Kardon amplifier.
I always had suspicion that rear deck subwoofer got weaker after the AX100 install.

I googled and found SVXdc / ae64.com with email and try to order wiring harness but no response.

Anyone have wiring diagram to Wire Harman Kardon amp paired with AX100???

I really want to utilize factory amplifier.

Please let me know.
