My latest project changes era again, back to the 1990s, after spending the last couple of months in 1930s Chicago and 1940s Pennsylvania. I hope to fit a Quantum Revolution soundchip into an Atlas SD35 and then detail the loco to show three different owners at once - Atlantic Coast Line, Seaboard Coast Line and CSX, with lots of patchwork evident. The first job is to make room for the speaker and soundboard, including the capacitor by cutting away parts of the loco weight. I also removed the dual-mode DCC decoder that came with the loco.   The next job is to make a seat for the speaker above the rear truck and fit the rear light. Ps. Those of you who have followed the progress of Sweethome Alabama may have noticed that the hill in the background has been somewhat de-forested - the trees went to Sweethome Chicago last month Jon |

Not a problem.
If you use a railmaster medium speaker, you can simply take electrical tape, make it double sided and tape the speaker on top of the truck clip. Then hook up the decoder on top of the motor and set everything ready and test fit the whole setup.
Once done, you can slide the speaker up in place, tape it in and go!
Got a few of them like this, but with Soundtraxx Tsunami.

Thanks for the tip - easy fix by the sound of it.
The speaker I'm using, is a bit long to negotiate curves with that method, so I'm building a 'seat' for it above the truck, with the rear light attached to it.
I couldn't find a turbo 567(16v) in the current Tsunami range, so went with Quantum Revolution instead.

Some decoders are just a bit too long when using a enclosure speaker from my experience. (I've done many Tsunami installs) My preference is the Railmaster speaker, thus why I suggested it.
Yes, good idea to build a seat for it out of styrene. I've done that also, you can even fit the styrene into the shell and glue it that route.

I finally finished the install tonight after a few busy days at work. I added some lead to the top of the motor to compensate for what had been cut away. More will be fitted beneath the long hood, when I start on the body. I modified the 8ohm high-bass speaker to include the LED for the rear light. This was the only way I could get the LED at the correct height. I also had to cut away some of the clear plastic from the lens/numberboard casting so the speaker would fit. The capacitor wires were shortened to suit and the capacitor sits loosely on a cradle made using the pickup wires and those for the front nose-mounted LED. Here are the photos     Even without the body-shell in place, I am pretty pleased with the sound quality from the speaker. Now to start on the detailling and weathering on the loco. Jon |

jon, I was wondering if you did in fact install a QSI or a Tsunami decoder. I'm interested to know because all the soundtraxx that I've installed into an ATLAS specifically yeilds poor running quailty. This only happens in the Atlas models and I've heard others complain of that as well. Also I like the Railmaster speakers as well. They just came out with a new rectangular 14mm speaker that should fit in anything when you have limited space. Also Jon, that looks like a nice clean install.
