   You will need an amplifier and an audio source. Depending on the connections of your subwoofer, this can vary. Choose a bass-heavy song and listen for rattling. If the speaker is "blown", it can be fixed, but it's just a pain in the ass and professionals usually charge a bunch for such a small problem. I'd be able to better help with more info (pics, model numbers, etc.)
