Check to see if all the speaker connections are in polarity ( all + to + connections and all - to - connections in their corresponding places)

also you could check to see if the speaker cables are not exposed and touching any metal surface from the amplifier to the point of where the speakers are installed, any contact would cause a short and force the amp into protect mode.
hope this helps, need any more help let me know

SOURCE: Autotek XS-900.4 stuck in protect mode

Hi.

The amp does not go on protection only because of wiring or power source problem , but also and mainly when there is an internal fault.

Protection is started whenever an out-of range voltage value is detected from the controller circuit.

Protection can be triggered from a burnt final IC or from a speaker wiring problem.

Since you have ruled out speake, wiring and power source problems, then this Amp is probably defective

If the Amp works fine on a different vehicle, then protection mode may start either because speakers impedance is not within Amp specs, or because the amp has a too big power draw. In this last case the problem is fixed installing a capacitor on the Amp 12V line.

Regards.

Ginko.

Hello
There is some short inside the internal circuit board. Normally, this short will occur to its audio output section. If any audio output IC get shorted, the set will switch to protect mode. If this mode should chage to normal, you have to find out the damaged component, and should replace them with same type and number. OK.

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.

Aplifier gettieng protection signal and excess heat


for that amplifier, it is recommended that you are driving a 4 ohm load. It can drive a 2 ohm load, but will produce more heat and shorten the life of the amplifier. Is the subwoofer a single or dual voice coil? You'll want to make sure that you're not running below a 2 ohm load or you'll always go into protection. Also, try disconnecting the speaker wire completely from the amp so nothing but power is connected. If the amplifier is still in protection mode when no speakers are hooked up, then the amp is bad and will need repair or replacement.

Amp in protect mode


Most time they go to protect there is something shorted in power supply. And at times it could be a bad amplifier transistor.
