Greetings from the Netherlands! I have recently changed my BMW 5 series for a DS4 and I have to say I am delighted with it. I do have one niggle though, and that's with the Denon HiFi - I've turned the bass to full on the eMyWay system but it still ""¦ it still sounds flat - has anyone else noticed that their subwoofer doesn't seem to have much bass? Do you know if there is a way of increasing its volume?
