[QUOTE="keep_hope_alive, post: 7339889, member: 576029"] if you say "Ground the RCA" it doesn't tell someone what to do. ground what? the center pin??? that would be a bad idea. that's why I clarified how to do it. the purpose of grounding the shield on one RCA is to verify if something inside the deck (ahem, Pioneer) has failed resulting in noise due to a lack of continuity to reference ground. Really, it's just a Pioneer fix because of their silly diode. And since all RCA shields are internally tied to signal ground (not always chassis ground, and does not apply to balanced two-wire systems) then you only need to do one shield. in the future, don't say "ground the RCA" since it isn't telling the whole story and someone could damage their gear trying it improperly. instead, provide proper advice by suggesting they "ground the shield of one RCA at the head unit). details are important when giving advice.
