1) Make sure the amp is properly connected to +12V power source. 2) Make sure the amp is grounded well, directly to metal - if you have a voltmeter, an easy way to check the first two is to see if there are 12 volts across the power and ground wires. 3) Make sure the speaker output wires aren't touching each other. If none of these are the case, there is an internal problem with the amp and it should be serviced or replaced.

SOURCE: protection light
take the amp out and hookit up to the car battery and let it charge then unplug it do this a couple of times then rehook it to the cars audio system it sounds like your amp may be locked..
also check your speaker wires from amp to speaker box then from the back of the box to the speaker inside the box you may have a short..
thats where i would start.. hope this helps

9 times out of 10 if your amplifire is in protect mode and evrything externaly, like speakers, fuse, voltage, etc. checks out fine then
either you have shorted out output transistors or power mosfet transistors. Basicly that just about what happens with car amps.
It's easy enough to fix IF, IF you know what your doing. First you
need to check the output transistors with a digital volt meter on diode check, If they check out then check your power supply mosfet transistors. I can almost guarantee this is your problem. Very common. I buy non working amps all the time and repair them. Listen to pbabin also he has helped me out. Good luck
