Somebody can tell me how can i install sound decoder DSD at-100 lc in engine athearn ac 4400?what do i need for install’
That will be a rather difficult install, as it is designed to fit inside a Genesis or Atlas model, which are ENTIRELY different from the BB/RTR models.
You will need a small soldering iron (15W) with a very fine tip, a method to machine a speaker mount. (See http://www.tonystrains.com/technews/tank_spkr.htm)
This is one of those jobs that if you have to ask, you are not ready to do. Try some simpler installations first.
