Tips to Keep Subwoofers From Cutting Out

Here are some general troubleshooting tips to ensure your subwoofers work for years to come.

Try Different Cables

If you are using a wired subwoofer, faulty connection cables often cause the speaker to cut in and out. As a matter of fact, this simple issue is responsible for the vast majority of these subwoofer problems. How to fix it? Easy; just keep a number of connection cables on hand and whenever you experience the subwoofer cutting out, replace the cables. If you notice immediate relief from the problem, then it was the cables. Swapping out the cords should always be your first troubleshooting step, as it is the cheapest and easiest fix.

Grounding Issues

Some subwoofers, along with regular speakers and record players, need to be grounded to avoid any connection issues. You may notice that some stereo cables come with a third grounding cable and that most subwoofers have a ground connection input. If your speaker is cutting out, try connecting this grounding cable to your subwoofer and to your preamp or receiver. The grounding cable looks like a little, for lack of a better word, pitchfork, though some feature rounded edges.

STAT: When the bass cuts out at high volume, the problem is usually in the amplifier. However, depending exactly on how your subwoofer is ceasing to function, you could also have a wiring problem, an electrical problem, or even a problem with your subwoofer or subwoofer wires.. (source)

Move the Subwoofer

This is more of an issue for wireless subwoofers, but if your speaker is too far away from the audio source, try moving it closer to eliminate any of the aforementioned issues. This can even happen with wired speakers, as long cables of 20 to 30 feet cause latency which can lead to this problem.

Why does my subwoofer cut out at a high volume?

This is likely a preamp issue or a voltage issue. Fix a bad ground by adding a ground wire, replacing the power wire, looking for any loose connections, adjusting the bass volume at the speaker terminals, and adjusting parameters on the preamp.
