: Non Premium Stereo Upgrade

05-23-2010, 07:20 PM
I just purchased a 528i and love the car with one exception. I did not get the premium stereo and the stock version I have is very weak. I don't generally like to add aftermarket equipment that might cause warranty issues but am open to any suggestions to improve the depth of sound quality. Thanks!
