2019 - Starlink problem caused by custom audio install; Warranty concern?

I started a thread a couple of months ago but now that I know details of my problem I'd like to start a fresh thread.

I have a 2019 non-nav Limited. Good sound is really important to me, so I decided against buying a factory audio upgrade and having a custom audio system installed. Details of the install are here. The install consists of an external 6-channel power amp (125 watts per channel) connected to the stock head unit, and six new speakers replacing the stock speakers.

Some time after the installation was done the red error light on the overhead Starlink console came on. I got an email warning saying the STARLINK emergency services in my car may be inoperable. The STARLINK Emergency Services such as Automatic Crash Notification, SOS call, Stolen Vehicle Locator and Enhanced Roadside Assistance—may not be available. Since these functions deal primarily with your safety, security and remote services, it's important you stay connected. Please contact your Subaru Retailer right away.

I checked some of these services, which work fine: calling SOS (red button) and Info (blue button), as well as Vehicle Locator from my computer. Other stuff I'm not sure.

Eventually I took the car in to service. They checked the problem, it has to do with Telematics, and I took a picture of the three error codes that appeared - see photo. 1. Left Speaker/Audio Circuit 2. Right Speaker/Audio Circuit 3. Mute Line Circuit. They cleared the codes, and the red error light went away. But a few days later the red error light returned, along with the same email warning. The service department said the amp was changing the voltage level of the audio connections, causing the error. The car's electronics are very complex and can't be altered like this. The bad news is he told me my warranty could be voided because of this. :frown2:

Before I go back to the audio shop, I was hoping to get some advice here. Could the installer have done something wrong to cause the error? My hunch is that the installation is not messed up, and the amp is creating the problem, like the service guy said. But shouldn't the car be able to handle an amp install like this without causing problems? I appreciate any advice.

As all of you seem to have a lot of knowledge on this subject I’m hoping you can answer this for me (in simple terms). Just bought a 2020 forester without the HK system. I am looking at adding a powered sub. I would like to tap into the rear speaker outputs to run the high to the sub. So now for the questions.

1.) will I run into this same starlink problem using the rear speakers instead of the front? (No speaker amp here so I’m not adding extra back into the system)

2.) I popped the grauments on the rear doors and it seems as if there are 3 speaker wires going to each speaker. These are the exact same color on both sides. Obviously I only need the+&- so any clue as to which of these would be them and how to tell them apart at the back of the head unit? Each door contained yellow, green, black, and red. These were all 16-18 gauge. Additionally (and I’m assuming the speaker wires) each door contained purple, pink, and grey. These were all around 22. Gauge.

You won't make Starlink mad unless you use custom speaker circuits that go around the stock ones.

Reading this thread with great interest. Looking to add an amp and component speakers up front in a 2021 premium. Would either of these add ons allow Starlink to function properly? Vehicle specific and advertised to retain stock functions. "This harness also provides connections to the factory speaker wiring, which you can conveniently use for your aftermarket amp's outputs."

I reroute the speaker level signal to the 2015 amp. Then route the amp speaker wires back to the behind the harness so I don’t have to pull speaker wires again. I even left all 4 pairs speaker wire to the car unconnected and I did not get any error from my starlink when I drove. So, I don’t think it is an issue with speaker signals. I think it is how the shop is tapping into the wires to get the line level signal.

2021 premium w. base stereo. Just had installed a JL 3 channel amp, Focal component speakers up front, and an Alpine sub in back with remote control. Kept the stock head unit and rear door speakers. I tested Starlink before and after install, no issues. Used a JL Audio LOC22 line out converter between the Starlink module and the amp. I'm very happy with the results.
