I have to say here is a link to a youtube video where you can kinda here the problem

. I just installed the x910bt into a 2000 audi a6. I have a terriable humming noise when the rca for the speakers are pluged in I have the metra wiring harness for a factory amped bose unit . I performed a bypass and only had 5 wires i had to solder on the kit , postive,negative,memory,illumination,and amp signal wire.

Ok I pulled the deck out 2 inches it went away now I got to figure if I need to keep all those wires extreamly far away from the deck lol

Pulling the deck out seemed to fix it upon closer attention going closer towards the speaker it only softend the hum/buzzing noise im still proplexed .

You might want to check the resistance on each cable between the center pin and the outer rim on each RCA plug. I am guessing one or more has bad insulation. Be sure to unplug the connector from the head unit before you test the plugs.
