I had to add LOC (which converts balanced differential to balance standard signals) to get rid of noise and to be able to use normal amp with differential BMW HU output.
2 questions Sam:

1. With the JBL amp you tried, was that with RCA connectors straight onto the speaker wires, or did it have speaker level connections?

2. Which LOC did you use in the end?
