Re: amp overcurrent problem
Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down (overcurrent), the amp likely has blown output transistors.

this can only mean 2 things, either your over working the amp, which means your amp is trying to push power that it don't have, and it's getting hot which is known as thermal mode. and the other reason can be that make sure amp rms. matches the rms. of your subs.
when the overcurrent light lights up, this means the amp is being run too hard or too loud. try cutting the gain back a little. i always hated putting in the sony amps that had those lights on it. it seems that when you turn it up and get it sounding good the light comes on.... if the overcurrent light is on all the time and it doesnt make sund....the amp could be bad. good luck.
sounds to me like you are overheating the amp, try down tuning the peak level of the amp, and also if there is anything around the amp clear it away, check if the fan is turning on, you may need to replace it,
use a bigger ground wire for amp and protect mode will stop clipping and shutting amp off also make sure power wire and ground wires aren't the same size ground bigger .............if this doesn't help change settings on amp to lower power
easiest way to set amp is (turn the knobs on amp all down turn up your system to the level you listen to normally and then set the amp knobs for bass turn knob slow to set properly but i think the ground needs to be bigger and maybe moved to a new location
hope this helped
If the overcurrent of DC offset lights are not green, the amplifier probably has blown output transistors.
To eliminate other problems, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up normally (all lights green), the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
