Re: 147 sound system BlOwSE !
do a search, some people are not impressed with the sound quality of their bose units, I have not heard the alfa bose setup but did try a honda accord (i know) with bose a while ago and the sound was rubbish!
assume it simply wasnt configured right and was on the base default setting.
I have the regular system in my 156 and that lacks the tweeter in the rear doors, so i have lowered the volume at the back as its too mixed and muddy.
i am almost happy with it.
play with your settings.
