No rush, I will not be available to work on the car for the rest of day but I will be back at it tomorrow.
Yeah @eduard4us and I figured a bunch of stuff out.
So instead of turning off the DSP, and with upgrading to 6.5" rear pods, I should just change them to speaker or speaker/sub via Forscan and flat EQ of flat EQ on 727-01-02?
If you have B&O then your 727-01-02 setting is already set to off, because the EQ on the B&O setup is run via the DSP rather than the ACM. There is nothing for you to change.
Are you on LUX? If so, follow RK's advice above. If you are on a 6 speaker with delete, then my post applies. When using tweeter alone, you are allowing the system to apply a high pass filter and by using speaker/tweeter, you are telling the amp you have 2 speakers connected in parallel and running a lower impedance than you actually are. That's why speaker is the correct choice when going up to 6.5's for the sound bar. And of course speaker/sub if you want to turn on the wiring to the amp in the rear for the sub. As for the EQ, the 01 setting is to help the cheap ass factory speakers better produce freq that they suck at. Going to the flat EQ (00) setting allows upgraded coax's to perform as expected without over emphasis of certain frequencies...
Great information. So much floating around in terms of Forscan settings, but pretty basic options for base system.TLDR:
3800 mod only changes front speaker settings. You need to also change the middle code block at address 727-01-01 to affect rear speakers. This post contains a list of all the code values you can use and what they do.
FULL POST:
What I have detailed below is applicable to my 2021 4 door Base. YMMV.
My "as built" values in ACM were:
727-01-01 382B 14F1 0098
727-01-02 0901 000D 0048
The conventional wisdom I've read on this site says changing 727-01-01 XX** to 00 or 01 will send full range to rear speakers. In my internet searching and tinkering with ForScan, I can confidently say it doesn't do anything to my rear speakers. And I don't think it does anything for anyone else's either.
My as built front power source and left speaker specs was 2 = internal power, speaker and tweeter (I believe S&T sends the widest range of frequencies from the list of options). I wrote 3 (no front left speaker) just to confirm my cheat sheet was right. It was. When I wrote value 3 in this spot the front left speaker went silent. I changed value back to as built, as it seemed like the right value to use based on the options below.
Front right and center channel specs: my as built was B, which is speaker and tweeter for front right and no signal for center channel (base has no center channel). Again I tinkered to confirm the list below did what it says it does; the as built value seemed appropriate so no change.
Here's where it gets interesting... rear power and left rear speaker specs. As built value was 1 = internal amp, tweeter only. I changed this to 2 = internal amp, speaker and tweeter. I perceived it to get slightly louder and when turned up mid frequencies would break up the stock speakers a little. I think it's sending a wider frequency band, and that's what we want!
Rear right, sub, and rear center specs... as built was 4, I changed it to 8. Both rear speakers now sound like they are getting pushed slightly harder. I have replacement speakers and 150 Hz blockers on order that will be installed next weekend. I'm expecting to hear an even more noticeable change once those are installed and for the midrange slop I hear in the factory speakers to disappear.
moving on to section 727-01-02, this is supposedly the various preset EQ options. I changed mine from 01 to 00 and didn't notice a lot of difference, but that may be due to the crappy stock speakers. I'll try changes at this address again once I get new speakers in. What's not clear is if there are actually different EQs assigned to all the values below or if some of them are simply unused placeholders. My ears couldn't tell with factory speakers. What we do know is some upper trims have as build value of 00 (flat response) here, but my base has value of 01... so there's at least one real EQ preset in the list otherwise every as built would be 00.
Some other things worth noting as I played with these changes in ForScan:
1. I used the fader and balance to isolate changes to the speakers I was tinkering with. Every time I wrote a change the fader and balance would reset to center.
2. I was playing music through CarPlay to listen to these changes so I could repeat the same track over and over. When I was done with my changes and went back to satellite radio I found that it was back to demo mode. I had to call Sirius to push my subscription settings back to the vehicle.

I think I'm missing something....based on spreadsheets the original 727-01-01 Ist set is As Built 382B. If you change to 3800, that would change third number from 2 to 0 (speaker only), but the last number I don't see an option for changing B to 0 on any spreadsheets? You would have to change it to 3 for speaker only. Correct?Correct.. others’ experience might vary but 3800 and 0901 were the sweet spot for me, big difference over stock Settings.
As for the sub - if you ever want to really fill out the complete spectrum of audio then you’ll need one. I was able to get a little more base out of the upgraded kicker speakers (particularly the 6.5” kick panel ones) when I added the Key amp but it definitely won’t give you full spectrum audio. Adding the Kicker Hideaway 8” was the perfect solution for me.. made a monumental difference in the total sound output of the system and I’m extremely happy with it. Small form factor too so it doesn’t take up space. I mounted mine in the trunk area as pictured
Great information on cyanlabs site. Am I viewing correct drop downs for front and rear stock?TLDR:

My original as-built was in fact 382B and I do in fact have it currently running 3800 and it does in fact work great... on mine at least.. non-B&O mid package setup
Got it. 0=SO Non-Tweeter Only, SCO Non-Tweeter Only That's from the CYANLABS. On the spreadsheet I'm only seeing options 3,7,B, and F. No options for 0 for xxx*-xxxx-xxxx
Could always experiment and change it back if it doesn’t work right.. save a copy of your original specs obviously
Definitely., I'll try a few after speaker upgrade, but just trying to zero in on what may work best based on others.
I'm new to this stuff.....what's the difference between SO and SCO?
