Front speakers only produce static

Depends on which sound system you have - BOSE systems in Devilles have two left front speakers!
If it's an amp problem, you will have an error code (DTC) set which you can see with a code scanner.
Check to see if the L/R balance control is working properly - cycle it a few times to make sure there are no dead spots.
If it's the door speaker, it is probably water damaged or it has open coil wiring and will need replacing.

PULL FUSE OUT AND PUT IT BACK,GET SOME PINK FLOYD AND CRANK IT UP REBECKA.

No, it's not supposed to be like that. It's blown.

switch wires around at speaker ... your polarity is backwards

take out the speaker in question and test it.
a 9v battery is good enough to 'burp' it.
if it makes a scratchy noise when you put power to it then you have a short in the voice coil.
Burping a speaker is just a short power up. Don't hold power to it.
Tap it on and off like a music note measure.

either inlet manifold or head gasket,big job best advice is to trade it in against the goverments trade in plan and buy a new small car like a VW polo or beetle or a mini ,or better still a citreon C3 diesel ,60mpg on this vehicle think of the saving on petrol and the enviroment

if your truck has bose the you probably blew the bose amp and will need to bypass it now to prevent speakers from making noise.

Hi, check to see if you have any surpressor fitted to the alternator?

try different speaker if works .its the speaker. if another speaker does the same .your radio is the problem.
