Moin. with me is the purchase of a new vehicle. I have the DS4 in the Performance Line+ variant over the weekend. So far I like the vehicle, I am partly really enthusiastic 🙂 However, I am extremely disappointed by the sound system. Hardly any bass available and the settings hardly affect the sound. Have tried everything possible here in the settings.. Does anyone have experiences about this? Is there an update here to improve the sound? As a comparison, e i a current B-Class with Burmester. Thank you!
