Stage 1 and Sub System Review
Here's a link to a thread over on bimmerforums, where one of the most experienced installers in the country installed a Stage 1 and Subwoofer System into an E90 3 Series. He was more than impressed, to say the least. Unbiased, user generated reviews are always nice to receive, but when you're talking about an IASCA (International Auto Sound Challenge Association)winning competitor, we couldn't be more pleased. If you're in the Atlanta area, or the Southeast in general, I highly recommend having Jeff work on your BMW for you if you choose not to do it yourself.
