DCC GP9

I just purchased a Bachmann GP9 diesel #6431 B&O (Blue and Yellow) with DCC onboard.
What do I need to do for the sound at it's optimum?

Click on the search button at the top. Enter GP7 sound install and bapguy in the by user box. My thread will be the first one. Scroll down for photos and how I did it. I used a Tsunami decoder # 828020 and a 1" speaker. Joe
