I have had a 2017 C250d AMG Line Premium Plus since January. The audio was excellent as it has the Burmester Audio as part of the Premium Plus Pack. However, I have recently purchased a 2015 C63 Premium. It is the same model car and although the C63 has the Premium Pack, this contains the Burmester audio as there is no Premium Plus Pack for the C63. However the C63 audio has virtually no bass at all compared to the C250d. Before I take it to Mercedes claiming there to be an issue, I was just wondering if any knows if both these cars would have the same Burmester audio system or is the system in the C250d better than the C63?

Thanks in advance.
