For the output side you can just use a multi-pole switch, I used to have 
opposite system ages ago where the  'music centre' (yes I'm that old) could 
output to local speakers in the lounge, or to the 'study' or both with a three 
position slider switch. And a lot of wire and solder on the terminals round 
the back! Putting two devices into one set of speakers would work just the 

Input is a bit trickier in that you need to shield it, but providing you put 
the switch in a metal box and connect the co-ax shielding to the box it should 
be OK.

BTW about three years ago I wrote a piece for the now defunct Micro Mart mag 
about fitting a 12V power amp intended for in-car use to a desktop PC,and 
driving the speakers from the above-mentioned music centre. It's powered by a 
molex plug from the PSU and fitted into a spare drive bay. It still works. 
Copies on request.
