Commonly, a blown subwoofer, issues with the connection and wiring, volume and other settings, input problems, short circuits and issues with the speaker can be some potential reasons behind a subwoofer not working even if the amp has power.
How can you tell if your amp is blown?
How do you diagnose an amplifier? Test the sound by unplugging the sound cables or colored RCA wires. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers. If the noise doesn’t stop, then you probably have a faulty amp to replace.

Check all accessible fuses and use one fuse in the amplifier.
What happens if an amp is not grounded?
Turning your system up creates a demand from the amplifier for more current. Without a good ground, your system cannot create this current, which creates clipping issues with the amplifier. Properly grounded systems help stabilize voltage levels.

Your speaker system isn’t loud enough
If you crank your volume knob to the max setting and the audio still isn’t loud enough — at least not without sounding horribly distorted — that’s a dead giveaway that there could be a power issue affecting the sound quality.
