Hallo Greg

I think you can do like this.

You need 2 switches (1 pol ON/ON)


!---------------- To amp A
!
switch 1 o-\ o switch 2
In-------o \------o
o---------o
!
!---------------- To amp B

Switch 1, Switches between amp A or amp B
Switch 2, Switches between singel amp or Both

I hope i understand the schematics
