How does yours sound now that Sam has played with the settings?
Seriously it sounds amazing... even surpassed Sam's expectations I believe... I wasn't expecting too much when going to see him as I know sometimes it's tricky, but I had the biggest smile on my face on the drive home, even took the long way round as I was enjoying the sound.
I've had the Alpine upgrade on my previous E92 335D and had BMW loudspeaker system on my E92 320D... This system is far better than both of them defiantly a noticeable difference.
Hope that helps... p.s. I used a 2 channel harness an use the head unit to power the rears.
