I have a bmw 2012 f20 125i with the base stereo.
I have upgraded the front speakers, installed an amp and fdl coded> hu_entry> AUDIO_SYSTEM_CIC > to 'hifi' using esys.
This definitely reduced the sound level and improved the sound quality, by reducing some of the high frequencies. However the bass is very low so I'm not happy with the end result evening with turning up the bass adjustment to full.
I have read on other posts to updating >amplifier_variant >to 'internal' will improve the bass. However I can not find amplifier_ variant under 3002.
Does anyone know why amplifier_variant is not visible?
I have NOT VO coded the ecu.
