Static noise coming from interior rear by speakers
I have a 2002 jag s type. there is a static noise that sounds like a speaker turned up real load without music. It's coming from the area around the back speakers and shuts off whn the car shuts down electricaly. It sounds like a speaker short but the noise is not coming from the speakers.

If the radio fader is adjusted fully to the rear and there is no sound the speakers and wiring should be tested.
Best way of testing is to remove the radio to access the wiring to the speakers. Identify the pairs of wires to the rear speakers and apply a 9 volt battery to each pair. If the speakers and wiring are good they will make some noise and the fault will be either the connection to the radio or the radio is defective.
If no noise is heard when applying the voltage, the rear speakers should be accessed, disconnected and tested in the same way. If you have noise it is the wiring at fault. If no noise the speakers are faulty.
The result of testing can be verified at every stage by using a known good speaker and a couple of micro jumper cables.

The fuse might be built into the cable to the lighterand/or radio. It's called "fusable link", this type of fuse looks like a cable. Or another type of fusable link might be in the fuse box under the hood near the firewall.
The volume control on your radio is called a potentiometer, which may be going bad. It works better when its warm because materials expand as they warm up and make tighter contact with each other.
It is also a possible a bad wiring connection exists. Poor contact will cause static, poor audio quality and intermittent output.
Your radio will have plug type connector(s) Your speakers will most likely each have two wires with single female spade connectors of different widths (keeps the polarity correct) the wire with the stripe (of whatever color) will be connected to the negative (-) speaker terminal.
So you need to check all the connections, one is making poor contact.
If both speakers (assuming you have two) sound good or bad... then start with the plug connectors for the radio and any independent black ground wire coming out of the radio.
If one speakers sounds okay check the connections on the other one. You check the connections by carefully pulling the speaker wire off of the speaker and then carefully pushing it back on making sure it feels tight and secure.
PS: If you pull the fuse for the radio, the radio will have no power and will not work. The radio coming on proves the fuse is good.
PSS: Your owners manual should provide lots of information on your sound system components.
The sound chip may have gone in the stereo, especially if someone has had it on very loud they sometimes blow, otherwise you have 2 speaker wires touching each other, that way you only get static noise, insidee the door they sometimes come free and touch the body
You should obtain a tool made specifically for removing door panels. They are attached by "snap" connectors, and by pulling on the door panel itself will invariably ruin it. Get the tool from a parts place and carefully peer into the slot between the door metal and the door panel. Use the tool slowly with resolution. You should really acquire a manual that guides you for your particular Jag.
Remember, to take the panel completely off, you need to remove the door handle. Look for a plug that has a screw under it. You'll need to pop the door window/lock control panel too, to access screws under there. This can be tricky, so be careful.
This might be a problem with the rear bearing brushes. This, unfortunately, is not a cheap problem to have fixed. An authorized Jag dealership will charge about $900 to fix this. And just as unfortunate, many other car mechanics will not touch a Jag from fear of messing something up.
Check the connector at the back, if the speakers had gone altogether is likely to be the cause. If it is not the connector, test the audio output on speakers on the stereo, if it works check connector and wiring to speakers, if you have no audio the stereo is faulty.
