Loving my non-crabbing (Yet!) C43 Convertible with Premium Plus but there is one niggle after a few days of ownership I have always upgraded the sound system in any car I buy and have enjoyed 400W to 665W systems from Meridien to Bose and was really looking forward to the Burmester "high end" system in the C43. Sound quality is great but I am totally underwhelmed with the base/volume - Just feels like the volume knob won't go past 6! Other systems of similar power will suck the air out of your lungs when turned up but this one just tickles your eardrums. Am I missing something in the settings or my expectations? - Probably just need to move on and enjoy the real soundtrack of the engine!
