How can I make my BMW speakers sound better?
Each BMW model and trim can have a different number of door speakers, amplifiers and have a greater or smaller variety of speaker types. Some stock BMW speakers sizes and arrangements provide an excellent sound quality, but others have room for improvement with aftermarket parts and amplifiers.
Another important thing to consider is the effect speaker size has on the overall sound quality. Usually, larger speakers are better for bass, and smaller ones provide higher frequency. And for more volume, you can try amplifiers instead of changing the BMW speaker size.
