Hi there
you will need to get a larger ground wire and it needs to be mounted to metal surface. this means you may have to scratch some paint in area where you will place the new ground wire (note do not add any other wires to this ground)
if that doesn't solve the problem than your settings may be to high on the amp but this sounds like a ground issue also make sure no fuses in amp are blown
hope this helps

If you disconnect your speakers and input and the problems remain it means you've blown your end-stage and the amp needs repair.

if the problem disappears when disconnecting the speakers you may want to check if the impedance of your speakers is within tolerance of the amp.

It goes into protection mode. how do i get out of it?


Check your speaker connections and speaker resistance of each speaker with an OHM METER. Most speakers are marked either with a 4 ohm or 8 ohm impedance. You might have a burned voice coil (shorted out) and the amp senses the short and goes into protection mode to protect the amp from being overloaded and burning itself out.

Amp goes to protection mode. if the fuse is too small?


Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. . Double check all connections. Good luck.
A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

My amp automatically goes into protect mode


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.

The amp turns on but goes to protection mode


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.

Why does my amp stay in protect mode?


The most common reason an amplifier goes into or remains in protect mode is shorted output transistors. To eliminate other possible reasons for it to go into protect, read the following page.

My amp wont go past protect mode


Disconnect all speaker wires and signal cables from the amp. If it powers up (no protect light), the wiring needs to be checked. If it still shuts down (goes into protect), the amp likely has blown output transistors.
