I have had my stinger for about 6 weeks now and I have noticed some quirks from the Harman Kardon speakers. First issue I have is it feels like the audio lowers itself and sometimes feels like the music from the rear speakers becomes more prevalent. I tried searching through the forums and gave up after a few attempts and keywords heh. Another issue I am having is the volume levels between radio/satellite radio and android auto. While using satellite radio I can get comfortable sound levels around 10 on the dial. For Android Auto I need to have the dial set over 20 to get the same volume levels and I feel I lose a lot of detail in the music. I thought I read somewhere here on the forums of issues with the head unit with audio levels and moving the speaker levels to the rear ones and it being fixed under warranty. Can't remember the code that was being used. I take my car in to the dealership next week for my 12k regular maint and I am going to try to bring it up. Has anyone seen these issues or maybe can direct me to a thread that talks about it? Thank you! PS Does anyone have any tips for using the forums search function that will give relevant information and doesn't spit out garbage?
