I've connected the 3 wires as shown in the picture: GROUND, GREEN, and RED (the latter 2 having their enamel removed). [PLAIN]http://img821.imageshack.us/img821/4133/nylonstranded.jpg [Broken] But I'm getting only low-volume (un-amplified) sound. Now, if I connect either GREEN or RED wire to the device's casing/housing (the metal part of it), I do get "normal" volume. Why is this so? Shouldn't this be the GROUND wire's job? PS. Perhaps the GROUND does have (transparent) enamel on it? I'll try to "remove" it either way.
