How to perform a sound output test on a Renault Megane III? It requires some knowledge of electronics and initiative, but it is quite simple. If you have a Renault Megane III with a factory radio that no longer outputs any sound, before rushing to buy a new radio, it is advisable to perform a test like this: it could be a problem with the speaker wiring, so changing the radio could be rewarding, but pointless.

The YouTuber removed the radio from its housing, connecting it to external speakers. And it works perfectly.

So the problem is not with the radio. Testing the wiring with an Ohmmeter, he found that the white and green wires have a low voltage, so they need to be replaced.
