First of, when you say your car audio isn't making any sound, are you talking about your head unit, or your amp?

Why would you not check for codes & make the proper
repair within a week of any check light,that is what is required

You say been on awhile,the vehicle had a fault code & system

any repair shop return your vehicle with a check light on

Neither you nor the shop seen to have any interest in
these check lights Why is that?

Try to check first the audio setting in the main menu, to make sure that the speaker are not set off or the mute setting. and you can use a multi media speaker or computer speaker and install it at the audio output of your tv to be sure that you are getting sounds, if you are getting sounds then the problem can be in the power amp circuit, but if you do not get any sounds the problem would be the sound processor circuit you may need to bring it in the repair shop or you can contact a service technician to repair it for you and save you from stress good day and best regards.

My amp suddenly stopped working last night. As

You have a bad amplifier section and your unit will need to be repaired by a technician. I would disconnect the speakers to prevent possible damage. In some cases components in line with the transistors will be bad in the amplifier also. There is no way to tell without electrically testing the unit in shop. Estimated repair cost would be in the 60 to 80 dollar range depending on the number of parts that are bad and the labor rate in your area.

Radio is on, but no sound. 2003 Olds Silhouette.

I had avery similar problem with my radio. At first I would lose audio but it would eventually come back. Then I lost it for good. I replace the radio and that work for a bit and then replaced the speakers and they worked for a bit. Eventually no audio. I took the radio and speakers back to the tech who installed them and he found a short in the speaker wiring to the passenger speakers. He installed a jumper around the short and the new radio and speakers worked fine. Then I had him put in the original raidio and speakers and have had audio ever since.

JVC dual bridgeble AMP

Have the speaker checked out and if it checks good you need to take the amp back to the repair center and have them test it better. Most repair centers have a 30 day warranty on the work they perform. Make sure they know what the problem is in detail, so they know how to check it properly. But my first thought is the speaker could be faulty. You can check the speaker yourself by switching them at the amplifier. If the same speaker sounds bad you know it is the speaker that is bad. If the sound is bad from the other speaker, then the amp is bad unless it is coming from the head unit. You can also switch the RCA input jacks after that and see if the problem changes speakers, if so, the RCA output of the head unit is bad, but that is less likely.

Amp in protect mode

Check to see if the fuse is blown. If it's not, the amp is unfortunately fried. It would not be worth repairing the resistor in it
