I have an HO Bowser SD40-2F, dcc and sound ready. I have read the Stewart Hobbies dual cube speakers are recommended, but I have no experience with them. Apparently they just plug in? I am going to get an ESU loksound 21 pin decoder for the loco. Just curious if anyone has done one of those installs and if it is actually that easy.
Update.
spoke to a friend who is far more knowledgeable then I am regarding Sound installs, he said this is exactly what the did the bowser speakers for, however, apparently ESU has made a speaker that is approximately the same size housing but sounds much better. So I have sourced some of the plugs that are required and I am going to try that.
