Hello!
I've read through the forms and havent found a solution so maybe someone can help.
I've had my front speakers replaced yesterday at a car audio workshop and the guys noticed the old speakers were connected to the amplifiers in a weird way which messes up the sound quality.
The AVIC pre-out signals have been omitted completely, and the speaker out signals were used for the RCA amplifier audio signal. The unit is missing the 24 PIN ISO with the pre out RCAs completely.
They wanted to correct that, they adapted a 20 PIN ISO according to 24 PIN Iso schematic, from here :
