Have you figured anything out with this? Dealership ordered in a new HU for me, takes about an hour to install, but I honestly think it's a wiring issue.I bought the Rockford Fosgate upgrade for my 2018 Crosstrek and I have a question about how it was installed.
With the factory system, when I turned the key off, the radio would keep playing until I opened a door. After the upgrade, as soon as the key is turned off, the sound stops but the radio is still powered. Should it still be making sound until I open a door?
I'm wondering if maybe the installer connected the amp to the wrong power line. It seems that if the head unit is powered, then the amp should be as well.
If other people that have this system could comment on how theirs works, I would love to hear it.
