I just purchased a 2005 530i and I love it! I got out of a gas-guzzling Chrysler Aspen(Dodge Durango) and I couldn't be happier. However, I'd like a little more volume and bass from my speakers, anyone have any good advice?
You might give the Bavarian AutoSport foks a try. They have a Basslink add-on sub that out performs the woofers installed with the premium sound system. Its basically a plug-n-play add on (designed for the BMW system). I think that would be your easiest bet. You could always go the custom route but it would be way more expensive and intrusive to the systems. Cheers.
