I'm planning to upgrade audio in my XC70 from 2014 (P3) from High Performance to Harman Kardon/Dynaudio/Premium Sound (dependning on what I find on the market) and I have some questions.
1. Do I only need to crack CEM to swap High Performance amplifier by using VDash? What will happen if I connect a new AMP without doing it?
2. Will High Performance speakers survive the amplifier from Harman Kardon/Dynaudio/Premium Sound? I'd like to first replace an AMP and later the speakers.
3. Are older amplifiers (before XC70 lift) compatible with XC70s after lift? What I mean is if for example AMP from 2008 will work on my 2014.
I've found some information about audio upgrade on P3 in the following link but that isn't enough for me
