Turns out deleting the ANC module changes things a bit. Deleting it got rid of some weird distortion I was having of certain times. Also, the DTS neural surround works a lot better now. Best of all though is the engine note. The engine sounds AMAZING at WOT now. Only downsides are a tiny loss of audio volume at speed, wind noise increased a little bit, and other cars were louder on the interstate. Put it this way, she's still quiet, but she is no longer a bank vault. Oh and there are no fault codes when you delete the ANC. It is like the car doesn't know it was even there in the first place. Lastly, I'll post a D.I.Y if anyone is interested.

 

Please post

 

I’d be very interested to read how you did it. Thank you!

 

Sorry for the wait. For some reason, I didn’t get any notifications about this thread. Attached are the SM instructions. Make sure the ANC connector is zip tied when you remove it or else it may rattle. Ideal settings for me is +6 bass, +6 treble, balanced L&R, -1 fade, -4 center, level 1 SVC, and no DTS neural surround. Obviously experiment as you see fit.

 

Here is a pic of the ANC module. Part #s will be different, but box size should be the same.

 

why remove it?

 

To improve the low end of the sound system as well as improve the exhaust note. The ANC is tuned to drown own the low end of road and exhaust noise. This unfortunately comes at the cost of bass and the soundstage. I was also getting weird interference and deleting the ANC got rid of it.

 

Great settings for the audio if anyone cares is +6 Bass, +4 Treble, neutral L&R and Fade, -5 Center, +4 Subwoofer, and DTS Surround enabled.

 

SIR - I did this and listened to Down Under by Men at Work. This Krell system is amazing! why TF didnt they tune it like this from the factory?! I actually think it’s better than the ML in my Lexus with this setting

 

They probably made the middle settings the exact middle of the system's capabilities. I think the thought process was that the Krell system would attract audiophiles that would toy with the settings anyways and that the same Krell system was used for the JDM version where the target audience (boomers) would listen to traditional Japanese music.
