Well.. I need a little more information. Do you have the amp properly installed? Check your grounds, your power lines, your speaker leads.. if anything is out of wack, it will trigger the protection light.

My MTX 600xd amp light won't even come on. ... Red light comes on. ... one.. and some times it goes into protection... once I turn the car off...
Disconnect the speakers and then try it again...there may be a shorted speaker or wire if the amp comes out of protect after you disconnect the wires...if the amp stays in protect after you disconnect the wires then there is a problem inside the amp with the circuitry and it will need to get serviced by an electronic tech
make sure amp is not grounded out or shorted out like if u miss and touch ground to power or the other way around protect light usaully comes on be resets once u turn the amp power off then back on . if that don't fix it maybe ur amp needs some repairs inside.
The unit will need to be repaired by a technician. Most likely you have a bad transistor that is causing the protect mode to turn on. The only way to get the protect mode to turn off is to remove the bad part.
The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.
First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.
Same thing happened to me so I returned it for repair turns out it was an internal 25amp fuse on the output. Got it back an it sounded very weak now it does not play at all. Nothing wrong with my setup as I have now got an 800watt amp that is running great.
New amp sounds messed up... grounds are bad and sometimes the amp tries to draw power but cant... So it immediately goes to protect... All jacked up... Audio specialist could help... Repair shop if local ..
switch off the amp then take off all the wires off including the speaker wire and then reconnect the wires on like before the problem is that the amp is on protection and if that dont work then get it repaired another thing is make sure ur amp fuses havent blown.
