Give us more information, as much as you can. It could be a bad power wire, a bad RCA wire, a bad amp, a bad HU output, a bad voicecoil, etc.

Check what ohm load your subwoofers are at on the amp using a Digital multimeter. Make sure all the settings are the same. Ya could have blown a coil, a former or Many other things. Stat by checking what your subs are wired at. Maybe a wire fell out a terminal.

They have randomly started working again... wtf?

Obviously some sort of connection issue. What happened to the ports on your box?

This here for sure especially if it randomly started back working again..Id also look for a better means of ground,a bit more solid,but...its working for you.Loose wire somewhere to check for.
