RCA grounding blocks?

[Dexter]

hey im using the Kenwood AUX adapter on my MP919 and i am getting horrible buzzing. when i touch the two RCA plugs to the metal case of the radio, the buzzing is gone, and nothing but clean audio is heard. do you know if they make some kind of RCA grounding terminals or blocks? or should i just solder a grounding wire to the plug?

You can try coiling copper around the RCAs.. and have one end of the copper wire bolted to your frame.

Solder a wire to the sheild of the RCA at the source end and ground it, short of a wire as possible. The AUX device you're using has an impedance mismatch or isn't properly grounding the shield. Your picture is correct, but I don't know of any grounding block.

cool, i fixed it. i used 2 of those loop terminals and crimped them to a cable, which i screwed into the dash frame. on the RCA end, i had to drill the hole bigger, but i made it just right and snug so it fit right on the end and now i get no buzzing at all and it works. sweet.
