My amplifier cuts out as soon as I exceed a fifth of the maximum dial turn on the volume dial. All of the LEDs start to flash and I can only get the amplifier to work again by switching the amplifier on and off again and reducing the volume. Any suggestions gratefully recieved.

Hello KAMAL, This means that the unit is going into protect mode. This is typically caused by something internal or a speaker connection could be causing it. To isolate if it is a speaker or the receiver you would first have to turn it off and disconnect all of the speakers. Turn the unit back on and turn the volume up to 45 with no speakers connected. If the unit stays on then you will know that one of the speakers was causing this short to happen. If that is the case I would check all of your connections. If the unit turns off when the receiver has no speakers connected then it is an internal issue and it would have to go for service. Thanks, FJD
You may have to increase the size of you power cables to the amplifier. Both the POSITIVE and NAGATIVE wires should run directly to the battery. At this power level, you may actually want to install a battery right at the amplifier, and use the shortest possible cables between the battery and the amplifier. connect the battery Negative and positive terminals directly to your car battery using #6 cable as a minimum size. This will almost guarantee enough power for your ampl,ifier to run properly.
First of all find out the recommended speaker impedance for the receiver. Then find out the impedance of the speakers you are using along with it. Simple rule is the speaker impedance can be higher but not lower than the recommended value. If it is so the receiver will run hot and if you turn up the volume higher it will run even hotter and then the protection circuit will cut off the Amplifier output to prevent burn out of components. Even if you have one defective speaker this cut off can happen. To confirm defective speaker -- disconnect one speaker at a time and turn on the amplifier and play it at cut off volumes.If by disconnecting one particular speaker the Amplifier does not cut off -- THAT SPEAKER HAS A SHORTED COIL and needs replacement.
be sure the master volume is in minimum some amplifier has protect circuit when the volume exceed the maximum sound level to protect circuits from damage. try to disconnect speakers maybe one of them are shorted already
This will be a protection feature of the head unit. If you are not using an amplifier, when the power required by the speakers exceeds the power output of the head unit, it will cut out until the volume level is reduced.
If the head unit turns completely off, you may consider adding an amplifier to the sound system.
You may have speakers of an incorrect impedance attached to the unit since the problem occurs when audio signal level is increased and the current goes up.The unit is shutting down to prevent damage. I would check the speaker connections and make sure that the speakers impedance are matched for the unit you are using.
