Can you rephrase this. I do not understand. Do we reprogram the ID4? New software? Does the ID4 recognize the sub? Does it recognize the amplifier? I hear that US ID4 have high treble in rear. How does this system sound installed.
Can you give me the full part price list?
Thank you
It doesn't matter whether there is a tweeter or not, you can upgrade for better sound quality. This is not complicated. Few people in your country upgrade the audio of the original high-end models
The amplifier is new. not used. So there are no parameters. You need to import parameters using ODIS. We can provide parameters. Send it to you.
We only provide wire connection instructions. Do not provide coding instructions. And activation instructions.
You need to find a service provider that can complete it.
