Why do Speakers Crackle?

Sometimes it's the little things in life that just annoy the daylights out of you. Crackling speakers can be one of them. yesterday they were fine, today that annoying sound distorting your listening pleasure. But why.

3 Reasons your speakers might crackle

1. A loose speaker wire. This is likely the number one reason your speakers are crackling. It's also the easiest to fix once you find it. Check the speaker terminals on the back of the speakers as well as your amplifier and insure they have a solid connection. How does this happen? Think cat, dog, kid. 
2. Yeah, a loose wire. This time it might be within the speaker assembly itself. The wires that go from the terminals on the speaker to the speaker cone. This, unfortunately is not something you're likely to successfully fix yourself. 
3. It could be your amplifier. If the crackling is occurring when you adjust the volume knob on your amp or receiver, then it's likely dirt in the pot (potentiometer). There are potentiometer cleaners you can try to mitigate the problem but it's hit or miss. 

Bluetooth speaker crackling? Throw it out and get a new one.

There are other reasons like cone alignment which would only happen on very old speakers, but the most likely reason is a lose wire.
