Started off with a better ground wire for the deck, straight to the chasis and fresh metal.
Connected wires to the ground shields on the RCA's and this increased the noise. Connected these wires to the chasis of the deck and it returned to the level as before...also tried connecting the wires to the ground and it became very loud.

So...should I try and just run a better set of RCA's to begin with? The set I have are not poor quality by any means but not the best available either.

Mind you this audio noise can only be heard over very suttle music or between songs. I think its something simple I just haven't figued it out yet.
