As you have indicated there is no sound at all in the out-puts available.What this could probably mean the out put ic is dead.Another thing to remember is to connect the red positive wire to the standby wire which is mostly yellow in color.

Nick i believe that you have a simple ground loop problem. To fix that you'll need to run a ground wire from your EQ to the body of the car. (the shorter the wire,the better the ground)

Find the ground wire (black wire) coming out of your EQ. Splice a wire into that wire,and then connect that wire to the black wire coming out of your Head Unit,and that should solve your problem.

do you have the yellow wire going to a constant power source??
