Neuvo 2007 Rear radio Speaker

I have a 2007 Neuvo where the radio speakers are mounted in the rear ceiling, but only one of them seems to work.
I have tried the Fader and Balance controls on the Kenwood radio, but no luck.
Does anyone know how to remove the speaker/ covers so I can check the wiring connector ??

Hi welcome to the forum from Bridington.

On my similar vintage Sigma, the black metal mesh simply pulls out revealing screws to detach the speaker.

If you find the speaker wires are securely connected and want to test the actual speaker, remove the speaker wires from the speaker and connect an AA or AAA battery across the speaker terminals, it doesn't matter which way round. If the speaker is OK there will be a loud click. Then if the speaker is OK replace the wires, remove the radio (teenagers call them head units - presumably because it does their head in) and ascertain which wires are that particular speaker. Unplug the radio speaker plug, connect the AA or AAA battery to the 2 wires that go to the speaker and the speaker should do the loud click. If it doesn't the wire is broken somewhere. If it does, the radio is bustikated and you need a new one.
