Thought I'd write up improving the factory E46 10 speaker audio system. I'm going down the intergation with the factory system route which is $$$ debatable when you consider what a Dynavin can do and how easy it be to put a couple of amps off the back. I'm doing this as a techincal challenge as I work in IT communications and for my sins Manage staff rather than do much of hands on these days.
