Replace the speakers. Adjust the Fade/Balance and listen to find which speaker is popping. The popping noise is most likely from a broken cone in the speaker
It can be a defective CVC-joint or other things. Have it inspected by a qualified mechanic and they will find the cause of the popping noise.
PS I know the speakers aren't broken physically because the sound works when it's low battery and it makes noise but it will not do sound after someone was messing around on it trying to fix it.
The gas making the popping noise is hydrogen.
If by "popping noise" you mean backfire, it could be crossed ignition wires, or some sort of misfire.
Change your plugs.
Yes, that popping noise you hear is the first sign that they are breaking. It is caused by the disposition of the detectors in the cable or cable port.
When mine did that popping noise it was the fuel pump. But it could be a number of things. It depends on exactly what kind of popping. The Chevrolet Blazer wasn't the best of the bunch. They do really well as trucks. But the maintenance is that of a Toyota.
Yes, it is possible.
I would like to know. I have had a popping noise in my throat for about a year now. My doctor says it's harmless and normal since there is cartilage and bone moving in that area of the throat.
You will have to determine the source of the noise before you can fix it.
bad axle joint or ball joints and turn stops can make popping
A bad axle will cause that sound
