If your subwoofer stopped working, there’s a good chance it was blown. To check, unplug the subwoofer and plug it back in. If it still doesn’t work, try switching the input from AUX to SUBWOOFER on the amp. If that doesn’t work, the subwoofer is probably blown and needs to be replaced.
When you find that the amp is working properly and the subwoofer does not produce any sound, check the input cables. Any cable issue will lead to transmission loss and result in audio issues. Check and ensure that the input cables are properly plugged in and fix any loose cable.
