Wouxun KG-1000G-PLUS external speaker issues

[OldJunk2]

My old Jeep is noisy. I added a Lido headrest speaker and used a 3.5mm "Y" adapter to connect the speaker to both out puts as directed in the manual. I only get output on the external speaker to area b, no matter how I have the speakers set on the radio (radio, mic, both)

What is going on with this radio?

The Y adapter is the most logical issue. However and this may sound silly, have you turned both volumes up?
Also I saw this note in the manual “The radio must be powered off/on after external speakers are connected before they will become active.” 

Yes, tried all of that

Sorry to hear that, I hoped it was worth mentioning.

Electrically this should be simple.  Are you certain both output ports work? 
If a single mono speaker works fine plugged into either of the outputs individually then you know the ports both work and are active.  Better yet, plug two separate mono speakers with mono plugs.  Do they both work simultaneously? 

One last thing to try is to use a mixer to combine the two separate audio feeds.  Most mixers are meant for line level outputs rather than speaker level, but if you can find something that matches the impedance and will accept speaker level output it should work. Or you can use speaker level to line level converters and then run the outputs into the mixer, and then take the mixed output and amplify it to feed a single speaker, but that seems like a lot of work.

I ran into the same problem about a year ago when I tried several Y adaptors with my KG-1000G. All of the adaptors were stereo to stereo. They work fine when connecting a single mono speaker to a single port but not when trying to use both ports at the same time.

As I stated before, part of the problem is the impedance mismatch. And @SteveShannon a mixer would definitely help along with the correct mono to stereo y adaptor. 

The only thing I have not tried yet was using an actual stereo speaker with both left and right speakers in one unit. 

Some radios, like the Icom IC-2730, will push audio out for side A and side B from one single port. But the KG-1000G definitely won't.
