Here is a Project I've been working on , It's a sound box for my 4x8 layout . I switch cars on my layout so I wanted the flange squeals with out having to push a button all the time . This ia a soundtraxx sound-car mounted in a a radio shack project box plug to track power & a set of speakers . The sounds are good still playing with the CV's !!!!! :o

Interesting....What size speakers are you using, and where will they be placed..??

They are 8 ohm speakers & they will be under the layout .

Very cool!
