Tony,

Thanks for remembering! Yes, this is probably the third time i have has this happen!

To answer your question...all of the wiring that was done for the installation was either crimped or wire-nutted (?)

nothing was soldered

all cables are monster cables and the hot wires for the amps are all heavy gauge

I have the output from the Rio going to an MTX..which then leads to an Alping (for the sub)

I have the hot wire in the dash, from the stock wiring harness, tied into both the sony and the rio

i have the sled, the sony and the rio tied together and grounded to the stock ground..which is a much heavier gauge wire than either unit has

between the sony and the rio i have a noise suppressor

and again...this is the killer


When i hook the sony up directly to the amp, thus bypassig the rio..i have absolutely no noise!!!

that is why i think there is something going on inside the rio

and FWIW...one time the noise came back just about the same time i was have a dry solder porblem with the ide cable....
