Car Stereos: all speakers pop and static when turned on, fiberglass door panels, pioneer head unit

Question
setup:
2 - 6.5(front doors)
2 - 6x9(rear deck)
^ connected to small amp
2 - 12 kickers (powerbass amp)
pioneer head unit


so i took out the 6.5s out of the front doors so i could make fiberglass door panels and i had the speakers sitting around in the garage for a few days.. went to put the 2 speakers back in and the drivers side speaker was cracking at medium volumes.. then it stopped for a minute so i kept turning up the stereo to high volume to see if it would crackle anymore and all of all of a sudden all of the speakers started making a constant loud static noise and it does it as soon as i turn the stereo on and keeps doing it until i turn it off. so someone told me that maybe the front 2 speakers were grounding out so i unplugged both of them and all of the other speakers still have problems..... help =O

Answer
Hi Alani,

I'm not quite clear on the system setup: are the front and rear speakers connected to an amplifier, or just the rears?  And are you hearing the crackling and static through the subwoofers as well?

If your front and rear speakers are both running from an amplifier, then I'd suspect the amplifier is defective.  Otherwise, there may be a problem with the head unit.  I doubt the issue is a grounded speaker wire, at this point; usually an amp or head unit will just shut down if a wire is shorted or grounded.  But I don't think that all your speakers have failed at the same time, either; so if there's a problem affecting all the speakers, it probably goes back to the source unit.

Good luck!
