brax is a fine amp, i bought some of the very first when they imported to the US, back in '95 or 96, the 1400 & 1000 i believe, great amps

This really amazing build. I have an 2019 RS5 and put in

Navtv Zen V
Mosconi 8-12 DSP pro
Mosconi 4/10 powering front miss and rear fill
Mosconi 5/30 powering front tweeters/front mid bass and sub
Focal K2 3 way components active in front
Focal flax in rear
Focal 25kx sub in BBox (sub is too deep for Basser box)

I agonized over tweeter placement but ended up putting them in A pillar bottom location

cheers

Did you gents go digital into the processors and if you did so, does the subwoofer level adjustment still work? In other words, am I forced to go analog out of the zen v if I want to use the on-screen sub adjustment.
And what happens to the park assist warnings when going digital? On the SB the warning tone comes from the front left a pillar lower tweeter and the rear right surround (c pillar). As I plan on setting up downmix on (zen v) for a front 2 ch, rear door 2 ch (fill) + sub, so no front/rear surrounds or center, what happens to the park assist tones?

thanks

Yes digital toslink into processor from zen v from headunit most150 fiber connector. On 2019 the amp/processor on b&o is in driver side cubby in back so just remove and ad zen v.
Head unit still functions all work but I haven’t tried using tone controls. I set the equalization to house curve and like it for all the music I listen to.

All tones and phone still work but sometimes when music is loud (yes I like loud music) phone calls mute music then when rejected it jumps back to previous volume.

Hate it when that happens… oh well, first world problems, right?

I just got a 2021 S5 SB with B&O, I am trying to find some details on how to get to unit behind glove box while I wait for parts like the zen to arrive. When someone who obviously is pretty capable like you says its a "nightmare" that worries the hell out of me. I am confident I can install front three without issue (wiring through door gives me pause) but just how much of a "nightmare" is getting to that unit behind the glove box? Would it be worth taking to a high end install place to get to it or is it just time consuming? I did some digging on youtube and other forums and didn't see much detailed info. Any thoughts would be VERY much appreciated.

edit
Would it be the same method as if i were accessing behind the glove box in a 2018-2020? I saw you mentioned the unit was in the rear near the amp in previous years, but accessing the area should be the same as a 21, right?

Nightmare might be a bit strong of a word... but it was definitely time consuming to remove the glove box in order to access the MIB unit.


I also see you had also PM'd me with a few questions, so i will answer them here (for other's benefit):

Remove glove box and then unhook the MIB to get access to hook up the MOST (male to male) cable to the Zen-v in the trunk, you said the 500cm version will get to the cubby on the driver side.

You want a single female to double male splitter - like this one:

7.65US $ 10% OFF|Free shipping MOST Optic Fiber Jumper Cable Multimedia Connectors 2 Female to 1 male For Audi BMW Benz Porsche Amplifier unit|Flex Cables| - AliExpress

Smarter Shopping, Better Living! Aliexpress.com

I originally ordered a 400cm MOST extension cable, and it got me back to the trunk... but only as far as the passenger side. I had to get another 300cm cable to bring it over to the driver's side cubby area. The extra 300cm was a bit longer than needed, but better than being too short. If you can find a 600cm cable, I suspect that would be perfect.

You said splitter is needed behind the head unit, is that the MIB? If so, I unplug the OEM MOST cable, connect that to one of the two female connections on the splitter, connect the extension MOST cable (going to the trunk) to the other female and then connect the male back into the back of the MIB. Is that correct?

Yes, the splitter attaches to the MIB (located behind the glove box). I called it the head unit... but it's the MIB unit. As mentioned above; you need a single female to two male splitter. Unplug at the MIB and put that into the female end of the splitter, Then plug one male end of splitter back into the MIB, and the other male end into the female end of your extension cable. Then the male end of the extension goes into your Zen-V.

Since I have essentially the same vehicle as you, the NAV-TV - Interfacing the Future Zen-v should work correct? The NAVtv site doesnt specify a device for the 2021+ RS5, S5, or A5 but if its working for you, it should be fine.

Yes, the Zen-V will work for your vehicle... but you need to order the kit with the OBD programming tool. The MIB needs to be re-programmed for optical audio output. The OBD tool does it flawlessly, but you can also reprogram it with a Vag-Com (if you have one).

The programming tool also allows you to re-set it back to factory settings, when you decide to rip the system out and sell the car.

You also need to set the Zen-V dip switches to a Porsche setting (as the new Audi MIB and Porsche are the same. If you set it to Audi, then it won't work (thanks to @SkizeR for that tip).

Here's a link to the kit with the OBD programming tool:

I appreciate the clarification and taking the time while traveling to respond. All parts ordered, when they arrive in a few weeks I will make sure to log the build. Thank you again for paving the way, I am honestly shocked I couldn't find a single other build like yours.

 

[JimmyDee]

There are a few guys on the Audi forums that have done lesser builds... but I found none that were at the same level as what i wanted to do. It was a lot of research, and some trial and error. I've also owned a few Audis and a few BMW's, so this isn't the first MOST vehicle I've done a build on. But the new MIB is different from the old MOST25 systems...

I'm glad I can help a fellow enthusiast.

I'll give credit where credit is due... I mentioned him in my post above, but @SkizeR threw me a few information bones. He's a wealth of knowledge, and he's done a lot of Porsche builds, so he was aware of some of the quirks with the new Audi / Porsche MIB.

I have some resonix barrier and blackhole tiles i'm itching to put to use, Nicks videos got me into car audio some years ago and I made sure to pay it forward when i can buy his stuff. I would be a lot poorer if I was closer to NY that's for sure. Anyway, I have a bunch of parts for my audi enroute from China, Europe, and Coral Springs... Pretty excited to start in a few weeks.

The biggest hurdle for me is not breaking clips and doing the install clean with no scratches etc. This is my first European car that I will be taking apart. Personally that is the most impressive thing (other than tuning) about good car audio installation shops, taking apart a "difficult" vehicle and putting it back together again without a hint of work. I have about 20 tabs saved from audizine, diy, youtube, audiworld, etc showing how people have removed Audi door panels, trunk, glovebox, dash, run wiring through door seal, etc etc. Last vehicle I did a good job but the mistakes i made on that journey were painful for me, broken clips, tabs, stripped screws, scratched A pillars, etc. Uhggg.

Again, thanks for the contribution to the community.

 

[JimmyDee]

You'll find that new Audi's are fairly easy to take apart. They don't use cheap plastic clips to hold the door skins on. They have a series of steel posts that are welded onto the door, and the door skin has receptacles that these steel posts go into. You won't break any cheap clips on a new Audi... every new car should be designed this way.

would try to get the technical manual. really a lot of good stuff in there for basic finding bolts and tricks for taking off panels. also wiring diagrams. got mine at factory-manuals.com

 

[dkc7]

Nothin like a factory service manual. Prevent one f**k up and it pays for itself. I watched lots of u tube for removing audi door panels and unfortunately there are still guys yanking on the bottom of the panel to get it off. Anyone can make a you tube video!!!

 

[surfsq]

The beauty with Audi doors, is that they run two separate feeds of 16awg through the Molex to individually power the midrange and the midbass. You don't need to pull new wire through the Molex.

How did you use those two 16awg speaker wires? My plan was leave existing wires for when i sell it later and run new wires. I would be quite pleased if i didn't have to run two sets of speaker wires through each front door.

 

[dkc7]

If your factory amp has a 38 pin connector get one of these. It makes thinks way easier. Specially when u put everything back to stock

Been down this road... the connector you're referring to, doesn't work on the new Audi MIB3 units.
Totally different pinout configuration.

 

[dkc7]

I wonder if bruce meranda is working on a new pinout. Hint hint. Cause his 38 pin adapter is a real game changer.

 

[JimmyDee]

It's not his design... you can buy this pinout connector unit on Alibaba for 7 dollars...

1. What did you use for remote in? I have done a fair bit of searching, other than tapping into the fusebox I didn't see any wires I could use in the trunk area. Might have to actually get the FSM and look it up.
2. Did you research any other subwoofers for that box or is the Hertz just a proven winner you happen to have lying around? I would rather buy once cry once for the 10" sub, we have just over 5" of depth to work with and 15 liters of volume (iirc).
3. Did you replace your front door speaker grills with the ASS (non B&O) or cut out the blocked portion of the existing?

Next week I have to take my s5 in to get the Navigation database on the MIB3 reinstalled, I carved out this weekend to start the install so hopefully this won't cause an issue with Audi since the issue is covered by warranty. https://static.nhtsa.gov/odi/tsbs/2021/MC-10189150-0001.pdf


I will be taking a reading on REW of the stock system, then also get DB's for non sport comfort mode before and after some sound treatment. I am not sure how crazy i will go, I'd rather not add too much weight.
