Have you checked the REM wire, if it is the wiring may have gotten fried.
Or you may need to get new parts replaced within the amp.
Both issues happened to me.

Very likely to be a bad earth.
Check the earth connection to the chassis of the vehicle. Remove the screw/bolt and clean around it with a wire brush or wire wool.
May also be a good idea to check for continuity using a multimeter.
Remember to try to have the earth connection as close to the amp as possible, as this will cut down on the risk of a bad earth and will minimise interferance.

There are 4 reasons an amplifier tries to protect itself.
Overheating - thermal shutdown.
Over Impedence - The subwoofers installed are not configured into a load the amplifier can handle.
Output is grounded - a positive wire strand may be touching the ground terminal - a wire may be shorted, or a speaker voicecoil is blown.
Intennal problem - Output on amplifier blown, or some other component has failed.
Check your wiring to the amplifier again - if all is good - disconnect the speakers and try to power on. If the amplifier turns on normally - test the speakers for blown coils.
If the amplifier still goes into protect mode - the problem is internal and needs professional repair.

Hi does the amp return to normal operation once the volume is lowered? If so it sounds like the amp is seeing too low an ohmage due to the way the subs are wired & they are drawing too much current so the protection circuit intervenes to prevent damage.The minimum ohmage this amp must be operated at is 2 ohms so if you are running at 1 ohm this will cause the problem you are experiencing.
