2020–2022 BMW 3 Series stereo and speaker fit
In the 2020–2022 BMW 3 Series, the factory radio can't be swapped for a standard aftermarket stereo, so the usual upgrade is speakers, an amp, a processor or a sub. Factory speaker sizes: 3.5" front doors and center dash and rear doors. Audio MotorSports in Carson stocks stereos and speakers that fit and installs them in its own bay, often the same day.
