Noah, I am sending the units to the gentleman in Littleton to have the Sony option taken out. It gets rid of the sub output and changes the output to a higher voltage. From my conversations with the people who have done this, the output is then completely flat. I am gambling that I will then be able to feed the output directly to the amplifiers and not need any signal processing, summing devices, separate volume controls or such and retain all factory functions. I will keep you informed.
I did confirm that those are the correct modules that need to be reprogrammed.
