F20 with 676 HiFi - Upgrade options
Hi there
I just received my F20 116d a couple of weeks ago and I'm quite pleased with it.
The audio is the 676 HiFi option, which sounds OK, but I'd like a bit more punch and definition.
Is it possible/worth it to retrofit the Alpine kit into a factory 676?
Are there other options for upgrading?
Thanks!
