Static is coming out of one of the speakers - Bose 3 2 1 GSX System

There are many possible reasons. Few pointers.
Disconnect antenna and check for static. If it is still there then turn off everything on boat , including battery charger and check for static. If is gone then start turning on electrical devices to narrow what is causing electromagnetic interferencw. If your still have static then disconnect all speakers right on stereo harness. Start connecting speaker to individual output to check for static. If there is no static then one of speaker wire installed on boat is shorted somewhere. If you have static when connecting speaker straight to stereo harness then likely internal ampflier inside stereo is a problem

Static electricity could be causing the static . It's possible the way they were soldered together That's what I was told so I got sick of the static and gave my old ones away and got another set of speakers. They work fine. Was also told it could be the plug ins for my amp as well not being tight enough.

Check all leads are plugged in the right spots and are in good condition. Sometimes "static" is caused by plugs not connecting properly.

That means that if too much power is going to the speaker or extraneous signals are being picked up by the wiring, it can come through the speakers as static. Stopping static requires finding and eliminating that extra electricity from transmitting through your speakers.
If you're still hearing distortion, turn down the volume on your amplifier until the distortion goes away. If the volume is too low to be easily heard, the problem may be that your amplifier produces too much power for your speakers to handle or that your amp and speakers have different impedance ratings.

clean the dust from your computer dust causes static which causes your computer to overheat and all sorts of problems
be sure to wear an anti static earth strap before touching anything inside your computer try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your SOUND CARD dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

Speakers are't really capable of producing static but can REproduce static coming from the amplifier.
If speakers are defective they can rattle (loose cone) or can produce random scratchiness if the voice coil is going bad. This last can also happen if a speaker has a lousy connection from the amplifier.
But I'd guess that the amplifier is at fault.

When you say static that they both work but one is noisy or are you saying that the only one is making a noise and nocoherent sounds coming from either

try replacing the cable

The static is probably coming from the computer sound card itself. Turn the volume down on the computer mixer it should limit the static you are hearing.

Check for the Third earth wire of your computer else check for the motherboard taking earth for the cabinet.

 

Good luck
