Recently converted to DCC and now I'm looking at an engine roster of approx. 15 engines that need to be converted. I am assuming (hopefully I am not too naive) that the decoder installation is relatively straight forward-that there are instructions and help from here to get it done. However, converting older engines not designed for speakers has me concerned. Do the speaker mfg's offer instruction of a particular speaker going into a particular engine? What would you advise as a first step to really getting a hold on this project(s)? I don't have access to a club so I am kinda on my own. Any advise on getting an education would be appreciated. Thanks all.
First off a list of the loco's,manufactureers, and how old they are might help. Some lococ's are more DCC "friendly" than others. Also what scale? Steam or diesel? Joe.
No, the speaker manufacturers have no conversion data on what will fit what; that's up to you to determine through trial and error.
The best advice I can think of is, buy several sizes and types of speakers and enclosures to use for testing the fit. Steam engines will normally have more room for a speaker since it can go into the tender. I have several diesel locomotives that have absolutely no room for a speaker, and some not even a decoder, without access to a milling machine.
There are sites that have install examples, such as the Train Control Systems site, where they have photos and instructions submitted by users, or Tony's Trains and Litchfield Station, who do installs.
Rick Bell's RPM Clinics group on Yahoo has a lot of sound decoder installs in their library, step by step fully illustrated with photos. Problem is, due to the limited space Yahoo gives you for files, the constantly drop older ones off. So be sure to copy them down and save them if it is a loco you are interested in.

If you want an education on sound in a loco, then take look at

select "Tech Info" from the top line of options
go to the bottom of that 'page' and

Step 2. Research each DCC one and see if there is a drop in decoder for it. Or what the best decoder for each one would be.
Step 3.Research each one for sound and make certain there is a decoder that has the proper prime mover and horn/whistle sounds for that loco. If not decide if nnon-prototypical sound is OK by you, and what compromise decoder will work.
Step 4 .Examine each one where sound is to be installed and measure various places to fit (wedge) in a speaker. Some installs require milling of the frame.
Step 4. Put the list into priority order. And start working on the first unit. I do not recommend buying all the decoders/speakers up front. I've got piles of decoders and speakers I purchased for projects over 5 years ago that are still waiting for their turn. Try one at a time until you start figuring it out.
