I have the premium audio system and it seems whenever I use my phone to play music it is quieter than the XM radio even when at the same volume. The Bluetooth is really only slightly noticeable with the subwoofer when I play hip-hop and rap and the apple car play is very noticeable overall with speakers and subwoofer when playing hip-hop and rap along with when I listen to punk and hardcore. I have an iphone 6s and use spotify as my streaming app, dont know if that matters in case its an apple issue. Is anyone else having this issue or am I just crazy about this? Sorry if there is already something on this but I didn't come across it when I searched.
