Use as big a speaker as you can to capture the bass...the firebox is your friend! <br /><br />When it comes to the decoder, why not use two? I put a motor decoder in the boiler of my steamer and just used the sound functions of the Tsunami. It's true that there are some load-compensated sounds that you'll lose with this method, but it mitigates the concern of frying a $200 sound decoder by using a $25 motor decoder to handle the big current. I had to do some work to isolate the decoders, but in the end it was worth it. <br /><br />Since you're working in O scale, this may not be a problem, but I had difficulty with the Miniatronics 2-pin connector binding on curves and derailing the tender. I wound up using the Soundtraxx micro connectors and was very pleased. Litchfield Station sells some VERY flexible 51-strand 29 AWG wire that helps with these connections.<br /><br />Hope this helps!!Rhetthttps://www.blogger.com/profile/10859842186861843961noreply@blogger.com
