Follow these steps to troubleshoot the issue:
- Turn off the audio device.
- Make sure that the speaker wires are properly connected to both the speakers and audio device.
- Turn off any nearby electronic devices that may be interfering with the speaker sound.
- Move the speaker wires away from any electrical cords.
Most likely what you're hearing is clipping (sounds like crackling or popping), which happens when you try to drive an amplifier or receiver beyond its capabilities, often with inefficient speakers. It usually results in the damage of either the speaker or the amp/avr or both.
Another source of occasional static is harmonics that each piece of equipment sets up when operating. Properly dressing your cables away from electrical, mechanical interference may also help. Check each speaker cable for broken, cracked or damaged insulation.
Here are a few more easy tips for how to get rid of static electricity:
- Add Some Moisture to Your Air.
- Treat Your Carpets with Anti-Static Spray.
- Stay Moisturized.
- When All Else Fails, Use Metal.

On electric guitars, you do a lot of plugging and unplugging of your cable, and these actions can eventually loosen the output jack, causing a crackling sound through the speaker. This crackling indicates a disconnected ground wire.
Why do some speakers sound fine at low volumes but distort at high volumes? You're much more likely to hear distortion or cause damage if your amplifier is under powering the speakers. Higher volume means asking the amplifier for more power. If it is unable to provide enough, your speakers will distort.
Distortion of the output signal waveform may occur because: Amplification may not be taking place over the whole signal cycle due to incorrect biasing levels. The input signal may be too large, causing the amplifiers transistors to be limited by the supply voltage.
A healthy amp is likely to make some sort of noise when idle. Poor quality pedal boards, FX units or even guitars will feed noise into the amp that will be exponentially amplified. If the AC supply is poor or your outlet is not earthed well enough then it can create a humming or buzzing sound.
The majority of bass amps keep things simple and clean and there are a number out there that have some great built-in distortion. A lot of rich, heavy distortion can be had with older, non-master volume amps, as long as you're willing to get loud.
Always ensure the amplifier volume is low, as this will restrict instant feedback. Turn up bass and lower the treble: Low bass and higher treble create feedback. When playing music, ensure the sounds are robust to eliminate any feedback.
Unwanted distortion is caused by a signal which is "too strong". If an audio signal level is too high for a particular component to cope with, then parts of the signal will be lost. This results in the rasping distorted sound. Once the component's maximum dynamic range is breached, you have distortion.

To fix subwoofer distortion at high volume levels there are a few things that you can do to help minimise it.
- Reduce the bass level on the stereo.
- Turn off the bass booster setting on the amp.
- Tune the gain control properly.
If Your Amp Doesn't Power on at AllIn order to turn on, your amp needs to have power at both the remote and power wires, in addition to a good ground. So if you notice that your amp isn't turning on at all, that's a good place to start. If the remote turn-on wire doesn't have power, your amp won't turn on.
Loose wire connection somewhere in the system. Ground Loop Noise. Electromagnetic Interference. Low-quality RCA cables.
Crackling, squeals and feedback, excessive noise and muddiness or low output are all evidence of tube problems. Power tubes.
