Hello, I've had my M3 LR for a few months now, almost a year. My speakers for the past month have been acting up. When I play music at half volume or above the base tends to cut out for 5-10 seconds. It happens everyday! It's very frustrating when you're listening to music and your subwoofers keep cutting out. Is this a physical issue to where I have to bring the car in for service? Is there anything I can try to fix it. I've turned immersive sound off and on and it didn't make much of a difference.
