Hello everyone, do you know that after upgrading from the original amplifier to the HK amplifier, the 451 audio and amplifier levels need to be changed?

In my case, I had the HK as original, I did change to the B&W config when I was learning to do the config on Volvos. It's no harm, it changes the options in the IHU and the sound profile changes a bit. IIRC the "sound stage" settings are not compatible between the two, so if you mismatch the config, those settings just have no effect.

When I swappd the amp to a B&W, I ran it with the "HK" stereo config for while, without changing the speakers it just sounded better to me. But again, the sound stage settings didn't work on the B&W amp.

Once I swapped the speakers, then I changed the config to match B&W, as it does sound good when everything is matched ;-)

There is not much harm in trying the things out, just maybe some control doesn't work. The amp connection is optical, it's all digital MOST connection, there is no worry of any hardware issue like overdriving pre-amp voltages or anything like that.

Hello, may I ask if the 451 audio and amplifier levels need to be changed after upgrading from the original amplifier to the HK amplifier?

No, that is a legacy setting. Leave it as is.

Can anyone else confirm the way the menu will or won’t change on iCUP cars? I tried changing this setting on my xc40 recharge, and saw no change at all. I did not know I had to turn the car off and wait a while for the changes to take effect so I may try again when I get the chance but if others can confirm what should happen, maybe it’ll save me some time. 

FWIW, I have the HK with sub, and I actually disconnected the rear sub and added my own aftermarket sub in its place (fed by the audio from the rear sub, so the subwoofer control actually adjusts it). But if i can get more control of the sound with other menu options, I would love that.
