the styrene sheet, use a brush to brush liquid styrene cement
around all the edges, and let dry. When dry, cut away the rest
of the bottom sheet, and you have a nice, air-tight speaker
enclosure.
Install the decoder and speaker
Because of the limited space available in N-scale diesels, creat-
ing enough room for the decoder and speaker usually requires
some frame modification and some sanding of the inside of the
shell. Putting a sound decoder and speaker in an N-scale RS-11
is about as complex an installation as one is likely to face. The
general process of locating the speaker, locating the decoder,
and wiring the decoder to the speaker will apply to any sound
installation.
