You must be using speakers with lower impedance than what is recommended. This causes the amplifier to over load at high volumes.The protection circuit shuts down the Amplifier to prevent further damage. And please remember no amplifier is designed to run at full volume, same as a car speed - Even though the speedometer might show max: speed 200Miles per hour would you do it???
Have you checked the fuses inside the amp?Unscrew the cover and with the amp sitting on its back,remove the cover.You have 2-4 fuses,old round type,in there.
knock sensor is working at least right but unfortuanantly thats all that is working
it is likely a knock isue check the motor oil it is not un usual for a nisan to knock when the oil is low but on rare ocation it will kick so hard the knock sensor will activate
You definitely NEED a source signal for the amplifier to amplify!
You should have a Main Power Wire, a Ground Wire, A Remote Turn on Wire, and RCA cables (or hi level speaker wires if your amplifier has them) and the speaker wires to the subwoofers.

try hooking up your subwoofers in series. then connecting them bridged to the amplifier. as follows: positive from sub#1 into positive of amplifier left channel.. negative sub#1 into positive sub#2. negative sub#2 into negative amplifier right channel. turn the gain down as this will sound pretty loud.
check to see if the rca's have been disconnected from the amplifier or behind the head unit. if ok, thake a power meter and measure speaker outputs on the amplifier to see if voltage is present. can also check resistance on subwoofers to see if they are blown.
here is a short test you can try, remove the rca audio cable from the amp & connect a diskman or toher audio o/p device that you can hook up with the same rca wires, turn on the amp & see if you have sound. you can also remove the speaker wires from the sub & using multi meter read the ohm's of the sub, most subs are 4 ohm. Hope this help locate your problem
