green response is from my 2009 bmw m3 with individual audio package. Orange is my finally landing spot in the Audi. May tweek some stuff in the future, but it sounds good enough that I doubt I’ll go chasing it any further. I don’t think there is much farther to go without ripping out the stock amp and putting a full DSP in and custom tuning everything anyways

one final quick note, with the sub turned downed the low base response is pretty similar to the green line. I find that as you turn the volume up towards the max 5ish clicks the system tends to “max out” the sub freq outputs (I’m sure to protect stock sub) and as such the rest of the system gets louder those clicks but not the sub. I didn’t test this but it’s what my ears hear. Normally i I’m not one to have a +12 db sub curve, and at the level I actually tend to listen to stuff at I would guess it’s more like half that. If anyone would like any measurements lmk and I’d be happy to take them.
The Dayton DSA175-8 is a really good midwoofer for the price. The only reason I didn't use it was because I was concerned about it's bass performance in the front door location though looking back in retrospect, it probably meshes with the factory subwoofer better.
Regarding the sound position setting, I use ALL in my car with the fader set for a slight forward bias. I think that sounds best.
Finished my B9 S4 Avant install last night, massive thanks to the hard work and genius of both Bobby and Bruce, I was blown away by the results, second best $1000 (aud) investment after the stage 1 tune. Incredible.
My system - Faital 8ohms (3), Aurum Cantus (f), ac165 (r), dt24.3 (4). Didn’t touch sub (yet), 10uf crossovers as couldn’t find 8’s locally available. Dynamat in doors only and around speaker mount holes.
In the interests of giving back I managed to find some Audi Q5 speaker mounts (F/R) and bought them to compare to the Aliexpress versions, the 6.5 speaker mounts are very close but don’t fit perfectly - however - the rear set included tweeter mounts that worked really well. Put the tweeter surround on the tweeter then twist them in, takes a bit of force to get them under the lugs but once in they are tight and not going anywhere, very easy, no cutting or mods required, took maybe 2min.

Great find at Aliexpress ! They look exactly the same as mine, you need push quite hard to get them under the lugs but they do go in.
I’m not the right person to ask about the capacitors, my understanding is the included ones crossover at 3500khz, while the 10uf cross at 5000khz. An 8uf crosses at 4000khz. I went with 10uf because it was closest to what the experts recommend in these forums (ie 8 or 10).
A tip for the rear doors, it’s easier to unplug the cables on the door than the door card, took me a while to figure this given unfamiliarity with these plugs.
I have also been reading about capacitors, it seems that most people are using the speaker "impedance ohm" (4Ohm for the Hertz DT24.3) for the calculation but other experts online are using the "Re Ohm" which is 3.3 Ohm. https://hertz-audio.com/product/car-...-dieci-dt24_3/ I assume it shouldn't make a big difference but just curious to understand...
