I have an Atlas SD 24 that is decoder ready ( 8 pin) and a place to mount two speakers. If I want to add DCC control and sound, does anyone offer a plug in package with dual speakers pre wired so it can be dropped in the unit?
Welcome to the Forums [#welcome]
You would get 2 speakers that would be the correct size for the units and wire them to the sound decoder.
QSI and Soundtraxx should both have a decoder that would fit. The speakers would be wired in parallel or series depending on the electrical properties (Ohms)
Here’s a link to the soundtraxx site that helps select the right decoder.
You are going to have to make some choices on this unit. The SoundTraxx Tsunami is one of the best ways to go.
First off the SD-24 has a prime mover ( diesel engine) that is a EMD 567 with a turbo. I have looked on the SoundTraxx web page and see NO 567 turbo decoders made.
I think that I might go with the EMD 645 which is turbocharged. I would use the TSU-AT1000 decoder as it will be a much easier install. If you use two speakers they should be wired in series.
You might just go with a single speaker and leave one of the weights in. Make sure that the place where you mount the speaker is closed off and will make a speaker enclosure.
