Installed some speakers along with some tinted plexiglass.  The old style was a 1970's yellow plastic stuff.  We think this is a bit more updated.  And we needed a place to put the speakers.  These will connect to the radio and the TV.  which will go in side the cabinet.....we think...on some sort of moving thingy that we haven't found  yet.  But might....soon...
