Speakers have a crackle in the sound also rear speakers not working

Make sure the positive and negative wires for the speakers are correctly(not reversed) and securely attached to the mounted speakers and the speaker outlet wires on the deck

factory amps are located on the stereo unit itself or in the trunk but only if the car was ordered with premium sound and the possibilities of that car being ordered with premium sound is unlikely. so at the harness in the back of the stereo find the speaker wires and hook up a 9 volt battery to the said speakers that dont work if they crackle then its in the stereo if not its the speakers or wires to speakers with battery hooked up and speakers dont crackle go to speaker and test with a vom and test for 9 volts dc

bad signals

possible reasons:

Impedance mismatch
wiring is grounding out on frame/metal
speaker isn't OEM and is slightly "pinched" thus causing cone distortion

One of these three will be your issue.

Also, you may remove the speaker and leave it hanging with the wires attached. Knowing that no wiring is shorted and nothing is disturbing the cone, try running your stereo. Same crackling problem? It may be an impedance issue or you reversed the polarity on your speaker.

It will require some work but the solution is there if it was working before.

this is actually a quotation from a site on the net as i've wondered about it to

"Speaker wire has a mark or strip on one of the conductors this is to indicate polarity of the wire. When installing speakers to the output of an amplifier you need to observe the proper polarity. This is particularly important when installing a surround sound system with front and rear speakers. If the polarity is not followed then the results will be poor balance of sound and even cancellation of some frequencies."

BLOWN OUT SPEAKERS OR BAD WIRING

yes it could be going out on you, if you have empty slot on mainboard or another computer you can try it on,then you can confirm if it is broke or not. hope this helps, glen

usually, crackling is due to 3 things:

1) the soundcard (or sound device you have them plugged into)
The best way to test this is to plug in another set of speakers or a headset directly to the sound
device, and listen. if you don;t hear the crackling, than consider that idea scrapped.

2.) speaker wiring/cables. Check the wiring for cracks/frayed spots. Do you get any crackling during/after you move the wires? if there is ANY change, for the better or the worse, than you have your culprit.

3.) the speakers themselves. when the first two options above are exhausted, there's only the insides of the speakers themselves to blame. you might not have seen any cone deterioration- but other things could happen, such as deteriorating wiring, etc.

for new speakers, they are relatively cheap- Here in Canada at least, I can get a new 2.1 set for anywhere from $25-60. Although, I'd strongly recommend any of the Logitech brand speakers- most models have subwoofers with unbelievable bass (for the price) through them. I myself have the more expensive Z-5500 series from them (5.1), and I've been more than impressed.

you have defective speakers! you can repair your speaker change the spider suspension wire! thats why your speaker is crackle sounds!

Check the connections to the speaker and the receiver. Had a loose connection once that did the same thing.
