I used to have a Sportback A3 which didn't have Bose (judging by the fact there was no badges on the speakers), and it had the Symphony head unit. I now have a 3dr A3 with Bose and an RNSE unit (all installed at point of manufacture) however the sound in my Sportback was tons better than what I have now with the Bose sound system... why would this be?? By that I mean the bass was a lot better at low-medium sound levels even with the bass settings set at normal, whereas the new sound system has poor sound and bass even after adjusting the settings. There's also no effect of surround sound filling the car, it very much just sounds like it's coming out of the speakers in the doors.At first I thought it might be the RNSE unit not having as good sound output quality, but after reading about it a bit on here that shouldn't be the case. I was always impressed with the sound in the sportback so the difference in the 3dr was one of the first things I noticed, so something doesn't add up... and suggestions?
