I have a BMW 335 for a few weeks and just put in a Reus Audio System. All I can say so far is WOW! Reus added a sub in the rear with a dedicated amplifier, replaced the front tweeters, added 1 center channel speaker, 1 speaker in the rear view mirror, and 2 speakers at the bottom of the door panel. The rest of the speakers remain stock. Because the heavy lifting is now done by the new amplifier for the sub, the stock amplifier can now more easily power the rest of the speakers. The system was tuned and matched beautifully. It's really hard to describe how good it sounds. The system just comes alive with outstanding clarity and excellent bass. I normally don't write these types of reviews, but wanted folks to know there is a great alternative out there for someone who wants to upgrade their stereo with a well designed and implemented system but have it look totally stock. I'm a very picky person, but am very satisfied.
