I have a 2014 5 series F10 Lci with stereo audio system. I replaced every speaker with HK speakers and added new HK tweeters. The sound is great, but i want more. I've doing some research, and I found that I need to code my unit with HK system. So, I coded AUDIO_SYSTEM to hk_surroundsound and AMPLIFIER_VARIANT to most, as I've seen in more topics. But after this, "No Warning Tones" displayed on iDrive screen. That means i need to buy an amplifier, as the stereo system do not have one. What aftermarket amplifier should i buy to be plug&play with AMPLIFIER_VARIANT to most? I don't really want to buy the original HK amplifier because it's a bit expensive. Any ideas?

The cheapest way to enable MOST is the OEM HK amp. Other amp like BavSound that support MOST will cost you more than double HK amp. Also, it is not plug and play. You will need to run extra cables to turn on any amp with MOST. Fiber from amp to HU and KOMBI and additional power cable from battery to amp.
