Speakers 'Crackling'

I've got a Panasonic stereo setup with 4 speakers. When I plug our jukebox into the in-jack on the stereo the speakers crackle when the music is played. How can I stop them crackling?

You need to turn down the volume on the jukebox, your overloading the input on your stereo.

The thing is the output for the jukebox is independant, there is no volume control. thats why you need an amp or some sort.

If it is overloading made a patch cord with a dropping network using resistors.

it comes from the jukebox with rca cord (its like 30m long, i think thats the problem) and gets converted into the headphone jack for the stereo input

Actually the 30m distance would help in this situation the length would attinuate down the signal a little bit. I concur with wizard-Fred, if you have no volume control for the output of the jukebox, then your only option is to make a resistor network to attinuate the signal.
One thing that bothers me about your last posting, you say your going into the headphone input on your stereo. There is no such thing as a headphone input, the headphone jack on your stereo is an output. If you are really doing this then There lies your issue. You need to go from the line level output of the jukebox into the line level input (such as a tape input) on your stereo.

yea thats what i meant sorry. i meant it was the headphone jack size (3.5mm or whatever)

Ok, gotcha. Well try this. play some music and twist the headphone sized plug back and forth. Does it crackle while doing this? If so you may have some dust or oxidization on the plug/jack. take some WD-40 or 3in1 oil and apply it to a Kleenex. Then wipe a very light amount on the plug and plug ti back in and see if that helps.

If the crackling is not related to the plug, then I'm afraid you will still have to go with a resistor network

ok so where can i get or how do i build a resistor network?

Are you good at soldering? If so you could try splicing two 50k ohm resistors inline on the audio cable.

I have an an old school stero receiver 4 main speakers equializer and cd player hooked up it never made a big time crack noise before when turned on I recently rearranged componets and not sure if eq is hooked properly but has a startling pop at first then it plays lights out help if you can

I went into JB HIFI and they told me that the stero is only designed to run 2 speakers, so runing 4 was overloading it.

Fixed it by buying a new amp, works perfectly

Glad to hear you got it fixed.
