Should be a straightforward task to knock up a little switchover box for the
sub. One box. Three sockets. One double-pole double-throw switch. Switch
should be rated for several amps carrying capacity if your Sony sub is
passive, or just a small miniature toggle switch if it's an active type.

Connect one socket to the two tags in the middle of the switch, and call
this one " SUB ". Connect another socket to a pair of tags at one end of the
switch, and call this one " NAD ". Label the direction of the switch toggle
AWAY from these tags something like " MUSIC STSTEM ". Connect the remaining
socket to the remaining switch contact pair, and call it " DVD ". Label the
other switch position " CINEMA SYSTEM "

Oh, and it's bass, not base.
