Well Stan, I am back. I received a couple of MP3 players, I put one on to the chassis, connected the power input and then hooked up the amplifier to power and one wire to the MP3 and two wires to the speaker. I may have gotten a bad amp, it made no sound at all, but not to worry. I took the amp out of the system and put one of the speakers that I had purchased in its place and got the music. I thought the volume was a little weak so I replaced that speaker with one of my Fatboy speakers, a spare I had from some of my ERR Railsounds installations . Plenty of volume now, I actually had to reduce the volume on the MP3. It is a little late for Christmas but it is now playing Christmas carols, I plan on building one more in a box car and loading it with railroad tunes.
Just wanted to give you an update and say thank you for the pointers on building this, I am a happy camper now.
Ray
