Hello, I would like to have a new sound system installed in my C class Cabrio (2017). I made contact with a local specialist and already made an appointment. The following question remains to be clarified: End stage with DSP or without. Since I will only drive the car in the summer and then hopefully much open, I do not know if the surcharge is worth it. (12000-1400 without DSP vs. 2000 incl. DSP) I actually want a nice discreet sound, although I like to hear it loudly. Does DSP make sense with a convertible and wind noises, etc.? What would you do? Greetings!
