Why does my JVC RX-D411S display an error message when using a subwoofer?

If you're seeing an error message related to the subwoofer on your JVC Receiver, there are a few potential causes. The built-in volume control of the powered subwoofer might be set too high, so try lowering it. Also, if the front speakers are small, the receiver might not detect the subwoofer. In this case, check the subwoofer connection and ensure it's turned on. If needed, replace the front speakers with larger ones or try setting the volume level of the subwoofer higher.
