Neil - you're the one with several ex-highway-patrol
cars in your history
The nearest I got to a public safety vehicle was the
ex-DEA dodge dart undercover chase car. It had
the ex-Arizona highway patrol UHF micor in it...

I agree with Coy.

That's the trouble with most of these post, and all of them using
transformers. You are still driving audio back into the other output
stage. That will sooner or later distroy the audio output PA !!!

This sounds like a viable solution on the surface, however, it may be
more trouble than its worth. Care would have to be taken to get it to sound
decent. The speaker grill would have to be sealed properly. Also, be
careful if you use Maxtrac speakers for anything but Maxtracs. They were

Back in the sixties, I worked for a background music provider. He
used dual coil speakers for his customer installations.
Reason for the dual coil was:
Voice coil one: was for the music which the individual area
user could control the music level.
Voice coil two:
Ya right ...

On a seriuos note,I used to use an old powered stereo add-on eq/amp to
feed a couple of MastrII speakers which handled 6 radios.Advantage of
equalizer was to kill any CTCSS and chop off the highs to reduce hiss
and noise-worked very well! The inputs were a mix of cap and xfmr

Go over to your local car stereo shop - the place where they
sell those 500w amps and build the latest and greatest
boogie buggys or thump trucks - and get a pair of speaker
isolator transformers. They may not call them that, but

Then he split it into 2 wires and then butt spliced the wires back to

I think the Motorola Mitrek Consolette Base Station has a one to

Yes, it works really, really well!!
I used to use two speakers for four separate radios in my 1961
Dodge Seneca during the mid-sixties. I didn't use the 'big
capacitor' either.
If one of the radios was not turned on, it worked anyway.
I simply 'refuse' to tell you it won't

Here's what you can do if both radios are

ground side. This will not work if both speaker leads
are hot, this will only work if the speaker amp goes

side grounded:
Wire the hot side of each
