All car amplifier manufacturers will integrate a protection circuit to protect the internal circuitry from getting damaged if a problem occurs. An car amplifier can go into protect mode when the volume on the head unit is turned up almost to its maximum level or can continuously be in protection mode regardless of the volume level. Most car amplifiers will have a red color 'LED' protection light to inform you that it's being protected. There are many reasons why this problem can occur to your amp, so check out the solutions provided to help your overcome it.
1) Check if the fuse is blown out. If the fuse on the car amplifier is blown out, it will prevent it from functioning and immediately will put it into protect mode. So look on the sides of your car amp and locate the blade fuse. Once you have located it, grab it from the middle and pull it outwards to release it from the holder. Look in the middle of the fuse, if the small is wire snapped or looks burnt, the fuse is blown out and needs replacing with a fuse of the same amps.
2) Check if any speakers wires connected are shorting each other out. Locate the speaker wires that are connected into the terminals on your enclosure and amp. Ensure that they are not loose and that the copper braids are not touching each other.
3) Check if the RCA leads are firmly connected. RCA leads are used to feed the amp with input signal from the car stereo. If they are connected loosely, it can cause the amplifier to see it as a major problem, so it will purposely put itself stuck into protect mode. So check that the RCA jacks are connected firmly into both the amp and headunit RCA sockets.
4) Check the grounding is solid. If you have grounded your amplifier to a weak spot, the amp will not be getting sufficient current to operate on. So recheck your ground wire, sand down the spot with sandpaper and ensure that it is connected onto a bare metal. This will provide the best conductivity with the car chassis.
5) Upgrade to power and ground wire that is a large gauge size. If your car amplifier only goes into protection mode when you turn up the volume really high, it is because the car amp can't get enough current to circulate around its electrical components. This is because the current power and ground wires you are using are below the required gauge wire size. So check out the user manual for your amp, find out what is the recommended gauge size is for both power and ground wires and buy a new amp wiring kit according to spec.
