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?

If I had to guess you have a stereo to mono 3.5mm Y adapter. It needs to be a mono to mono or stereo to stereo 3.5mm adapter.

@MarkInTampa is 100% correct. Most Y adapters are stereo and not mono. Plus you will have an impedance mismatch whenever you go from to outputs into in one speaker. SO even a mono y adaptor won't work well or sound very good.

I'm surprised that you are only getting audio out on the B side though. I tried a y adaptor and I was able to hear both A and B on one single speaker but the audio was very muffled and just down right horrible sounding.

Wouxun radios do not have the ability to send audio from sides A and B out to one single channel like other brand radios do. I know my Icom IC-2730 has dual audio jacks but I can still hook up a single speaker to to the first audio port and hear both side A and B just fine. The IC-2730 also uses the second audio jack for programming and computer control functions.

I can give a perfect example of what happens when you use the wrong impedance speakers in car audio systems. Back when Chrysler used the Infinity speakers and cross over amplifiers for their premium sound systems, they used Infinity 4 ohm speakers. Replacing a 4 ohm speaker with an 8 ohm speaker results in horrible sounding and muffled music.

Yes I learned that lesson the hard way. I replaced a door speaker on my 2002 Jeep Liberty and didn't pay attention to the speaker impedance. I replaced a 4 ohm speaker with an 8 ohm speaker and was very disappointed with the sound. I realized my mistake once I pulled the new speaker back out and compared it to the old speaker.

SO the issue with trying to connect one speaker to two output jacks is twofold. First is the use of a stereo y adaptor in mono jacks and the other is you are getting an impedance mismatch.

I'm using a mono Y adaptor

The wouxun manual says to use a Y adapter for a single external speaker?

It might say that but a 3.5mm stereo y adaptor will NOT work. The sound will be low and muffled if you do. I can tell you this from personal experience because I wasted my time and money trying a y adaptor myself.

Again, I was hearing both A and B through the single external speaker but the sound was veery low and muffled. 

The KG-1000G manual is wrong when it says to use a y adaptor. Even if you did find a mono y adaptor, you will still have an impedance mismatch that will cause the audio to sound bad.

I no longer have the radio, but I remember that I was able to use a Y adapter, as discussed in the manual.   I have found that some of the cheaper adapters have really unreliable plugs and/or jack on them.   Do you have another adapter to try? 

If you plug the  speaker by itself into either A or B output, do you get good audio out?   (to make sure the rig's jacks are OK.)

To check out the adapter, try plugging the adapter into only A and see if you get audio from the speaker.   Try the same with the B output only.  Both should give you audio.

[OldJunk2]

I just ordered another one to try

Here is an easy way to test the Y-adapter. If it is working on one side of the the radio, swap the speaker out cables on the radio and see if the side that was working stopped and the other side starts working. 

[WRYZ926]

Good luck with it. I did as Mark said and it worked fine when using only one speaker port on the radio. But sound was horrible when both sides were plugged into both speaker ports on the radio,

One thing to check is that they are in phase with each other. Otherwise one channel will destructively affect the other. The same thing can happen acoustically with out-of-phase stereo speakers.

And that is probably the problem with both of my KG-1000G Plus radios. The different y adaptors never worked with either radio.

Can someone post a link to the Y adapter option for this radio? I’ve got two of them and may need to run an external speaker at some point.

The only thing I have not tried yet is using an external stereo speaker connected to both output ports on the 1000G. Most external speakers designed for two way radios are all going to be mono and you will have degraded sound when connecting a single mono speaker to two mono outputs on the radio. Again the reason is that you will have an impedance mismatch.

I know the 1000G manual states that you can use a Y adaptor. But that does not work in my experience when using a mono speaker. I tried two different 1000G radios and several different y adaptors and none of them worked when connecting the adaptor to both speaker ports on the radio.

The subject of impedance mismatches and degraded sound is a lengthy subject. You are best to google the topic yourself.

I think you need a speaker that is designed to have two sides input into the one speaker, like the Yaesu MLS200.

I have to agree with you on that. Most mobile radio speakers are not designed for more than one input. 

I will have to do some research on how the Icom radios are wired up as they can pass both side A and side B through one speaker using just one speaker port. Though you have to use speaker port 1 only to hear both sides from one speaker. Port two will not allow you to hear both sides from a single speaker. Port 2 is also used for programming and computer control.

While it is a nice feature to have two speaker ports on the KG-1000G, it would have been easier for everyone if there was only one port.

I wouldn't have bought a 1000G if there was only one speaker output. While the OP is wanting to merge both VFO (in Wouxun speak "Area") speaker outputs into one speaker, a lot of us want to have each them separated. For my base station I have a external speakers on ether side of my computer monitor and a different scan group setting on each side of the radio. I can quickly tell without looking what side of the radio is receiving based on what speaker is outputting. It's kinda like having two radios in one.

And I do the same with mine at home. That being said, it would have made it easier for mobile installs if Wouxun would change things so that both sides can be heard through a single speaker like the Icom IC-2730 does. Not everyone has room for a bunch of speakers in their vehicles.

I use the Icom SP-35 speakers with all of my radios in the home and in my vehicle. They are great sounding little speakers. I even use one with my IC-7300. I have also used one with my Yaesu FTDX10. And the SP-35 sounds better than the expensive Yaesu SP-30 speaker.

I tried the Icom SP-35 and Midland SPK-100 speakers with my 1000G radios and a Y adaptor. The sound was horrible and muffled even with the 20 watt SPK100.

It's in my Jeep, the radio is under the seat along with my Icom 2730 dual band. I have 2 external speakers, one for the Icom, one for the Wouxun. There isn't any room for the 3rd speaker 

 

I found out today that Wouxun makes the cable I need so I ordered it from them

[WRYZ926]

Hopefully the Wouxun y adaptor works. Please let us know if it does.

I am pretty much in the same situation as you with my 1000G in my Ford Escape. I have room for two speakers but there just isn't any room for a third speaker. One speaker goes to my dual band radio and the other to my 1000G. I just monitor side A on the 1000G since I can't hear side B with the main unit under the seat.
