So I'm looking to completely redo the audio in my 2019 forester. Since a lot of websites dont have anything listed for the 19s yet I decided to try to find what works as far as adapters and such. Here's what I have so far: The speaker sizes are Dash - 3 1/2s, Front Door 6x9s, Back Door 6 1/2. Speaker harness adapters appear to be Metra 72-8104 for the front and back doors. The dash had a different connectors which I couldn't find, so I just ended up just cutting them at the wire and spicing in the speaker wire ends that came with the speakers I used for the dash as I already replaced those. The speaker brackets for the front and back doors appear to be Metra 82-8146 (6X9s) and Metra 82-8148 (6 1/2s) For the Dash Kit, I noticed that the 2018 CrossTrek had the same radio design and look as my 2019 Forester. So it looks like the Dash Kit would be the Metra 95-8908HG Kit. Wondering if anyone has upgraded the head unit can confirm this. As for the radio harness, I have not taken my radio out to see what the factory harness looks like or how many connections there are. I'm also look to see what SWC adapter I would end up having to use to retain my steering wheel controls. Im also trying to retain my usb ports, mic and backup camera. If anyone has any good websites to check or knows what wiring harnesses and or diagrams that would work with 2019 please let me know. Im looking to replace the unit with a Sony XAV-AX5000.
