How do you test a subwoofer to see if it works?

Can you test a subwoofer with a multimeter?

Connect the multimeter’s probes to the positive and negative terminal of the subwoofer’s voice coil after setting it to the ohms setting, specifically in the 200 Ohms range. It is good if you get a reading between 1 and 4, if it shows no resistance, the subwoofer is probably blown.

How can I test my speakers without an amp?

Speaker Testing Option 1: Connect a 9 Volt battery to the leads of the speaker, positive lead to positive battery end and negative lead to negative battery end. If a pulse is generated in the speaker then the speaker is still functioning properly.
