Hi, did anyone tried connect F20 HK amp to replace F30 Hifi amp?

As seen on the attachment the connector are of the same totally. Can we just plug and play using the F30 Hifi amp harness?

Appreciate

The H-K and Hi-Fi amps aren't the same. You may be able to use the H-K amp but you'd have to code the HU.

Coding the HU NBT to harmanhifi shouldn't be problem. My concern is does it really work. If so then would be a good Plug and play upgrade

Because F30 original harman amp can't use back the hifi connector as it required fiber connection. Whereas this F20 harman amp seems like compatible with hifi connector

It should work, all input signals and speaker assignments are the same.

The difference is the HK(674) OEM amp having CAN Bus terminals, which the HiFi(676) OEM amp does not have.

Done the plug and play upgrade. And coding to hifisystem harman kardon. Any other coding I miss out?

Improvement: Mid frequency improve but high and low freq not stable and good as hifi 676 amp.

I'd get a Match 7BMW amplifier which is a plug and play replacement for the HiFi amp and has a wider DSP range and more power than the HK amplifier.
