The cooling fans do not come on at all, is there a menu to set the temp they come on or is there a secret menu i can access, also what is the shut off temp of this amp, it has gone up to 60 dergrees celcius and not shut down is that to hot?

It sounds like there's DC current on the amp output terminals. Disconnect the sub and test the output with a multimeter. If there's DC there, most likely the amp is shorted internally and needs repair.
You need to have the amp bench tested at a car audio shop. Sounds like a dead short in the amp. Try turning the crossover on the sub "off" and connect any other speaker to it. if you have the same outcome, your amp needs serviced. Post a comment with your results and if I can think of anything else you could try beyond that I will. Hope this helps
Hi the over heat will be a result of the fan not running. Most likely the fan itself is faulty, however could be the control also. (more likely fan). Make sure the fan is not being stopped by dirt etc, if you have a tester you can check and see if there is voltage at the fan (when the amp is hot), if there is, replace or seek someone that can assist. Best of luck
He may be right! You might try finding a new source of contact for your ground cause it may not be sufficent enough to ground to, also make sure that no wires from the back of your radio have any wires sticking out touching other interfering things that could possibly be causing the noise
Make sure that your amp turn on wire is connected from behind the radio to your amplifier. Usually the turn on wire is a blue wire but it can be any. This blue wire connects from the blue/white wire behind the radio to your small connection turn on connector on the amps power connections. You have 3 ( 12V , Ground, Switch or the smallest connector)
Also check the amplifiers fuses, and the main powerline fuse as well. If this doesnt work then write back to me.
you trouble shoot the problem by opening unit and force-powering fans to test for overheating during "being used loud for a few minutes". Read the fans' label for proper voltage to apply and proper polarity. I am guessing the fans will run on car battery voltage of 12 volts. Also, attempt to close up the unit to simulate real conditions.
There should not be fuses for the fans. If unit is now cooling, then look for faulty thermistor, which turns the fan on during rising temperature. Once thermistor is located, a fast test is to "jumper" its two wires to simulate turn on.
