If you have a signal RCA wire that is shorting out, this could be your problem so check to see if your RCAs are in-tact and not shorted. Amplifiers will also enter protection mode if there is a short somewhere.Vice versa, if your battery is low and the amplifier is not receiving a constant 12v, it will enter protection mode. If your alternator is producing too much power, it will trigger the amplifierвЂ™s protection mode. Most aftermarket amplifiers have a protection from low and high voltage.If your speakers randomly stopped working and you noticed that your amplifier is in protection mode, there are a few reasons why this might have happened.After finding the location of the fuse, pull it and make sure that the leads are not corroded and that the fuse has not been broken or popped.

Your manual should indicate which fuse is for the вЂњAccessoryвЂќ, вЂњCar StereoвЂќ, or something of that sort. Easiest way to locate the correct fuse is to look in the OwnerвЂ™s Manual and find the fuse number and box location.

If you do not have power, and you know for a fact your wiring is correct, check the fuses under the dash or under the hood (depending on your vehicle).

If you find that one of your power wires or ground wires are not correct, check your vehicle wire diagram and make sure you have the correct corresponding power and ground wires.

Make sure to use your ground, as well as another ground (like the frame or body of the car) while testing your constant and accessory to test that you have a good ground. Accessory will be 12v only when you turn the key to the вЂњONвЂќ position or the car is running. Constant will always be 12v, whether or not your car is on. If you have a voltage meter or a test light, test the ground (black), constant 12v (yellow), and accessory 12v (red) wires to make see if you have the correct voltage in the correct wires, as well as a good ground. Problem: Installed An Aftermarket Head Unit and Now It Has No Power Possible Solution: Blue/White wire located on Head Unite wire harness. If your car has any of these systems, check your AMP TURNON signal wire for 12v.

Many cars have built in amplifiers that require a 12v signal to be sent in order to turn on the Amplifier, most common being Bose, Infinity, and JBL.

Problem: Head Unit Has Power But No Sound Possible Solution: Get behind the lighter and tap into the positive wire and connect it to your RED Accessory/Ignition wire on your aftermarket wire harness. The easiest way to locate an Accessory/Ignition wire is to find a cigarette lighter that turns on when the car does. Many Jeeps and Chevrolet systems have a data signal wire that carries a very low voltage signal that tells the OEM Head Unit when to turn on, however it is not compatible with aftermarket units.

In some cases, car stereos do not come wired with a 12v Accessory/Ignition wire, making an aftermarket radio difficult to install and work properly.
