Giulia Harman Kardon Amplifier replacement

[Liska]

Hello everyone I am a 3rd generation alfist and qualified and audio specialised auto elec.
I am lately starting to see harman kardon amplifier fail on giulia and stelvio,
I have worked out a way to replace it with a high end amplifier dsp which will save you a lot of money (alfa replaces it with same problematic amp for around 7k) and improve the sound quality.
If anyone is interested I am in the Melbourne area.
