I installed this amp in mine, 230i with hi fi sound system. I installed their speakers and sub upgrades. I am finding the sound to be dull, not enough presence or highs for me. Is your tune sounding like this as well?

I had a 328 years ago and installed the Audiotech Fischer amp and Bavsound speakers in it. I tweaked it quite a bit and downloaded some shared tune files, wish I could remember where from. Tuning these amps can be intimidating and tiresome. Steep learning curve and probably a mic needed to measure the sound.

I'm gonna talk to a car audio shop about this. Seems ridiculous that bimmertech would not have a developed Harman target tuning for each car with their system. I was suspicious when I was configuring and they were asking me these dumb questions about what kind of music I like. (That shouldn't really matter)

For the premium they charge vs the Audotec Fischer amp you would think they would have some tune files. I had one of these years ago and downloaded some files other users had made and tuned them with the dsp software. It can be a rabbit hole and there is a steep learning curve.

I wish I could remember which website it was that had a thread with a bunch of users sharing them. Might have been here on the F 3 series forum.

Creating one from scratch is daunting and probably needs a good mic and tuning using a RTA measurement. Very hard and time consuming for the non experienced at this.

Yes, I found the default sound file to seem dull... not enough highs or lows for me, too much mids, didn't like the balance between front/rear, not enough gain, etc. I think BimmerTech probably setup the sound profile "correctly" using measurement tools, especially the sound stage with proper delays, etc., but different people like different sound characteristics, so definitely not a "one size fits all" scenario. Sort of like calibrating/tweaking your OLED TV for "perfect picture"... I usually find those settings too dull for my tastes too, even if they are technically "correct".

I think they do provide the initial tune for the car you have... it just may not be to your liking. To BimmerTech's credit, they did have me try another sound profile once I told them what I didn't like about the default one, which to my ears was a bit better, but still way off from what I prefer. When I bought the amp, I did have the impression that it would come with 10 different sound profiles preloaded, so you could try them all and use the one you liked the most without having to do any tweaking, but that was not the case in my experience.
