SOURCE: amp keeps turning off
an amplifier needs minimum voltage (usually 6Amps) to turn on. If there is 12V at the input of your amplifier, check the remote for 12V as well as making sure the ground is secured. I suspect based on limited information, that your alternator/charging system is the culprit.Take your amplifier to a local shop and have it bench tested (abuot $10) they will hook up to an independant power supply and verify its properly working. Then it can be eliminated as the source of the problem. Also be sure your wiring and fuse are accurate for the amount of current draw.
Since your protection has never come on, and the power light is going out altogether, you may have an input voltage problem.

There are a few things you should check:
Check that you have the correct fuse on your power cable. If it is allowing too much current, the protection feature of the amp will kick in. Similarly if the resistance is too high, there will not be enough current to power the amplifier.
You may also want to check the earth/ground cable to ensure that it has a good connection.
Try increasing the gain slightly on the amplifier (not too much or you will blow something). This will mean that you don't have to turn the head unit volume too high to get a loud output.
Nice amp BTW.

Sorry,after rereading your problem,I gave a wrong answer.Do you have the deck sub RCA pre-amps connected to the amp,then the wires from the amp to the sub?If you do,you need to check what the sub and amp are rated as such as,peak or rms.They are 2 completely different meanings.Greg
This is an indication that you have a problem on the power supply section or on the load because of the following reasons :
1. Over Voltage - the regulator might be cycling on over voltage due to lack of load.
2. Over Current Protection - excessive load or faulty power supply cycling will
trigger the over current protection circuit.
3. Leaky Capacitor - a dried up main filter capacitor or other filter capacitor in the low voltage power supply that is producing an out-of-regulation condition. A bad filter capacitor on the output of a series regulator may result in excessive voltage and the unit will not power up unless isolated.
4. A problem with the microcontroller, relay or its driver, or standby power supply.
This is not DIY and quite technical so I
