Didn't the Pro S Plus come with "VW Premium audio"? I think that means they are already using a separate amp and sub, but they didn't get Harmon Kardon/Bose/Bang Olufsen branding.
There are so few Pro S Pluses out there that I'm not sure how many folks have experience with this. I can check my wiring diagrams and see if I can share anything with you.
Thank you. I'd like to see what the diagram says before I go tearing into it and looking. I'm comfortable with reading diagrams if you share them.
yes, the 'premium' system is better. However, for the past 10 years, I've grown accustomed to the Porsche Burmester variety. While that system isn't competition worthy, it's quite good for an OEM system. My wife's EQS Burmester is also steller... So I'm willing to spend $12-1500 USD and 20-30 hours to get this all sorted out and bridge the gap. I'll never close the gap fully with that budget, but I bet I can get a lot closer.
On the "Plus" I am sure there is a sub/amp in the back, but I'd be surprised if there is another amp on the other 7 speakers. Once my amp arrives, I'll pull it apart more and see what other knowledge I'm missing.
I did find a thread on OBDeleven that discussed this very issue.
That thread is here:
https://forum.obdeleven.com/thread/21052/distance-error-after-speaker-upgrade
As far as coding goes, porsche allowed me to tweak the frequencies on each channel in the system. I didn't see that it was included with OBDeleven when I poked around. I've ordered the RossTech(?) unit to see if it has anything else interesting.
I may unlock the 5f SFD with OBD11 and see if it stays unlocked wile I negotiate it with my Launch programmer. But that's a topic for another thread.
edit I looked at the uploaded diagrams, but they are dated 5/2021, so they won't cover mine. Looking closer at the unit, I dropped the glovebox enough to see behind the panel and saw what pretty much looked like all the photos I've seen in this thread (and others).
edit 2:
@waldo22 looks like I found how to turn these coils off. I have 10 pairs of coils to in the car and 10 are 'installed' in the sound module (47) in OBD11 VAG. Control unit 47, adaptation, function configuration audio. I'll remove the pins on 1 coil each door and tape them off, then see what errors I have so I can then turn them off.
I also tried this, I eliminated one set of voice coil and turned it off. Turning it off disabled the speaker output. So this isn't a viable option.
I'll expand this list as I explore more:
6TT: is the left front door speaker
8TT: is the right front door speaker.
Edit 3 I looked, the media center said it was connected via ethernet, so it's not a MOST system on the 23 pro s plus.
Edit 4 While digging, I found this information.
5h0.035.453.a is the HK front door speaker.
5h0.035.453.b is the HK rear door speaker.
These should be a direct drop in and would offer improvement at a very reasonable price vs the Focal speakers. I'll edit back here as I find more. Though, this is likely well known, I just didn't see it in this thread when I read it.
Edit 5 I went exploring. The audio unit does have ethernet. Looks like two pairs of 4 pins going into a cable that looks a lot like a fiber cable, but it for sure has copper in it. No provisions for door speakers in the connector. The audio unit does have male pins where speakers should be. I assume I could move it to internal outputs (I forget what it's called in the coding) and get it to pass sound there. I may try it, but it may also upset the parking sensors. Hopefully it'll pass signal to the ethernet and internal amp and I can just turn off the channels I don't use, or at minimum wire in speaker simulators. Then run the external amp.
To make the factory amp happy, I had to remove the 4.7 uF capacitor from the Focal tweeter. I'm not keen on running it wide open, but it was a huge improvement.OEm didn't have a cap, so I assume some filtering is done at the amp. My wife sounds true to life from the phone now vs like she has her hand over in front of her mouth talking.
The amp part number is: 5H0035456E. I had to look at a 2024 model to find it. Mine seems late enough of a build that this is the case for several of its features. (Late september 2023). it did not get the bigger screen, however.
I'll keep prowling as I get time.
) I thought I would need closer to 8 ohm. But I got 10 for £2 and figured I could add 2 in parallel to get it closer to 10 ohm if needed , however 1 per channel works fine and doesn’t get hot. I get the feeling it doesn’t need to be exact. I’d be interested to know the spec of the original focal item , if you have a digital multimeter to test the resistance?
