Always great to hear !

I appreciate that.

It is definitely not wrong to have different ears, not always necessarily a professional, take a listen and adjust though. Competent and with some idea of what they're doing but sometime fresh ears could surprise you, in a good way.

Haha yes, but you can also take those ingredients back to Don and let him whip them together for you!

Not sure where or even IF I'll be able to get the perfect tune for this amp as most of the posts seems to be for the F series. Meanwhile I'm thinking about adding in an active sub to get a bit more out of the lower frequency

I've had the best luck with the two Reference curves I found online: Harman Curve and another file. Loaded those into AudioTools RTA and then a little fine tuning after that. I've been able to leave things alone with those two tunes. I think just one car audio forum shows up if you google Harman Curve Car Audio. Both of those txt reference files are there.

I did not read all the answers but Match is a brand of AudioTec Fisher, a german hifi company. Bavsound Revenant and Bimmertech Premium are also Match UP 7BMW and PP86DSP, respectively. If you go to audiotec's website. There is a database where you can download the default sound settings for your application.

The link--> https://www.audiotec-fischer.de/en/m...ase/soundIndex

For example, I downloaded the Convertible sound settings for the UP 7BMW.

I need to emphasize that this setup will assume you have factory speakers. So, if you installed aftermarket components, it may not sound right.

All correct but, unless they have since changed it, the Bavsound units are locked from doing your own tuning. Which is crap and like having an M3 with a 40mph speed limiter. For the cost of admission (the same as the UP 7BMW) you should be free to do as you wish with it.

Good point! I never owned Bavsound (or Bimmertech) so I did not know that they could not be tuned.

It's only the Bavsound, Bimmertech you can do as you wish (as it should be).

[ctuna]

didn't know that Bimmertech and Bavsound had DRM locks
on there Units. I won't tell anyone to buy from them after learning
this.

Yeah the default profiles on Audiotec Fishers website sound horrible with Morel Hybrids and Jehnerts. I have it so dialed in right now I'm not sure how much better I can get without adding a trunk sub.

Weighted A Harman reference curve plus mild adjustment, TA and turning the gain on the rears down to minus twenty are the biggest help. I've finally got air* and near perfect wide stage. It's like Taylor Swift walking away from the mic to far stage left during the recording and hearing her try to quietly slip out a fart. Turning the rears down to an inaudible level snapped the stage dead center with no more drifting slightly to the right on some songs and left on others. I wasn't aware of how much it was throwing a wrench into things.

From what I read, a sound system needs to be calibrated for aftermarket loudspeakers because of the response curves of the components being different. Unfortunately, I do not know anybody in my area who does that. I will try to do that with an RTA software myself once I add the aftermarket speakers. Is that how you did it? Or did you just tune by the ear?

I did it with a calibrated cheap Dayton audio microphone using the audiotools app on my phone. You can download the Harman txt file to your phone for audio tools. Select A weighted.

Just saw the software update and it added the Auto TA. Just noting that it's an great addition to this amp.

If you can live with your own "cooking", and enjoy doing it, then go ahead, but be conscious of the fact that you are not tasting/hearing the absolute best that could be.

I'm finally going to add a sub. It's a IDMax 12 and I was going to do an IB setup. Was going to double up 3/4" ply and screw it into the seat. What length screws did you use and were they metal or wood screws? Not sure how thick the metal is in the back of the seat.
