Rear speakers not working how to troubleshoot?

[Wpedrozajr]

Hi Goldwing family,
I hope everyone is doing GREAT!
I'm a new used Goldwing owner with a 2007 Audi, Navi Gl1800A.
Would it be ok if anyone can help me troubleshoot?
Both rear speakers have no sound coming out.
What, where and how should I begin to troubleshoot?

Check out the wires at the trunk hinges. They get bent back and forth so often that occasionally they break. Your problem is likely there. That or your speaker balance is not set correctly.

You, The main Viking, are the man!
The wires at the trunk hinges, both side, were all broken.
After splicing all 12 wires on each side, then using butt connectors, and reinforcing with electric tape, now I have sounds coming out of the rear speakers.
Thank you so very much for the advice.
A perfect example why this Goldwing Docs forum helps!!!

I just found the same thing on my wing. All wires completely cut on one side. I haven't checked the other side yet. I never used the bike speakers (always used headset) so I don't know how long it's been like this. Plus I just pulled it out for the first time in almost 3 months

I fixed the wires on one side and the speaker works fine. The other side didn't have any bad wires (that I could see) but does not work.

HELP PLEASE!

May LOOK fine but could be broken internally and not visible at all. Need to do some continuity probing with a meter to determine if the wires are ok.

Do what Steve F says.

On some, sometimes I can feel the breaks in the wires through their insulted coating.
