Have recently changed my e46 m3 for an F80 so are inspired to do another audio build. My previous system evolved over a 5 year period was raspberry pi based and was controlled by the bmw Nav head unit. Had dsp and 2 x components speakers front and back and a ski pass vented subwoofer. Audio was digital to dsp and music was mainly from lossless Flac cd rips. Amps were 110 rms x 4 class AB and 600 rms class D on bass. System was tuned to run up to 80% of amplifier power to avoid clipping. For a car audio system it sounded quite good. Move forward 14 years in tech the F80 is far better in terms of taking most forms of usb / Bluetooth/ DVD audio sources. This one has NTB id4 which is the last of the text based menu system and the build is 6 months too early to get the newer gui interface and CarPlay/ Android auto software. The F80 I have has been imported so spec is interesting. Has connected bmw modules, can self park , lane control etc but has only the base audio system for some reason. But from my point of view it’s ideal for an audio upgrade as not too many speakers to replace. This thread will be about uplifting the audio system to above HK level. Pic courtesy of Pete
