[Nathan]

I am looking at buying one of the 8289X 2-6-6-2's and would like to here from people that have purchased one and put DCC and Sound in them.

What speaker did you use?
Which DCC /Sound unit?
What problems did you face in doing the install?
What do you like and not like about your unit after the install?
If you had to do it again, what would yo do different?

Thanks for the help.
