So, it started about a year ago or so but when I first turn on my car, I would get nothing but static coming from the center front speaker. Then they will slowly start working after about 30 minutes or so. Sometimes when I start it, it will work as if nothing was wrong, but most of the time it was static. Today I was driving when I heard a noise come from the front driver door speaker then the whole sound system stopped. No sound coming from anywhere. The radio display was still on but no sound whatsoever. Help please.

From the description it sounds like component failure in the amplifier. The amplifier is in the trunk on the right side. The static then working sounds like a component that would heat up and then function and now it has finally failed in a way that turned it all off. Step one would be to check fuse 15 in the fuse box under the right side of the dash. If it has blown you could replace it, but I suspect it will fail again. To test if it is the amplifier, you could take a speaker with a couple of wires and go to the amplifier and unplug the B connector which is the input feed. Then use the speaker with the radio on and check that there is audio at those connections. If there is audio at the input but not the output, then it's internal to the amplifier. If there is no audio at the inputs, then it is a bad radio module. The amp unit is plug and play so if it is bad, you could likely find a used one and swap it out.

Okay, so I replaced the fuse, and it blows after about 5 seconds. I have to find a speaker to do the other test.

If the fuse blows that fast, it's likely not worth it to do the other test. That fuse only powers the amplifier, so if it's failing that fast the amp is the issue.
