Another approach is to build or use an aircraft audio panel, which gives 
you two or three audio outputs. This is not entirely unlike the Motorola 
consoles that have select and un-select audio channels. Check out Bruce 
Lane's installation: (Controlling it all)

 Hello Folks,

 I am wondering what people are doing these days with multiple two-way
 radios and scanners in their vehicle and then outputting it to one speaker
 in the vehicle? How are they isolating each radio?

 Thanks,
 Mike

Mike,
If you decide to combine, make sure you look at the speaker circuit on each
radio.The Spectra for example will smoke if you take it to ground. You would
want to use a 1: 1: Transformer to isolate it unless you have a good
combiner circuit.After asking the same questions you are asking, I decided
on three speakers mounted on the side of the center console. Two years ago
next month I was at Dayton and had a vendor who was selling speakers put
audio into different size speakers. I then took the three SMALLEST I thought
I could like with. Much better than the built in speakers.
Goood Luck.JIM
