Protect light will never go off

I've been unable to complete installation and test the speakers that I've got because of the protect light. At first I thought it was something to do with the subs so I've temporarily removed them, but the protect light remains on. I've tried about 3 or 4 different ground spots, and am using zero gauge wire for both the ground as well as power from the battery. I've also tried a few different spots for the "other positive cable" (it runs from the amp between the positive and negative large cables... unsure of name, earthwire?, ...usually goes into back of deck to determine whether to turn on amp). I've tried placing it in different fuses in my car like power windows and power seatbelts because they have a higher amperage and I was worried that that could be the problem. I seem to be fairly lost as to what to do next. The only suggestions I have left require me buying a new fuse for the power cable as it could be blown, and/or getting the installation done professionally. Neither are really viable options for me because I'm poor.

Re: Protect light will never go off

Unfortunately, it sounds very likely that you have a defective amplifier. Usually you see a protect light on an amplifier because of an internal short, supply voltage too high, voltage too low, or speaker connections of too low impedance or grounded. If your speaker wires are completely disconnected, that eliminates the most common external cause of a protect light. Also, a protect light from the voltage being too high is very unlikely without the engine running (and an alternator problem). The "other positive cable" you're referring to is the remote input, and it won't cause a protect light no matter how it's connected. You'd need a voltmeter to do much more troubleshooting; a protect light can be caused by a very poor ground connection, or it's possible that a poor connection at the battery or fuseholder, or a defective fuse, is causing a severe voltage drop. However, based on what you've described, it seems most likely to me that your amp is defective.

How do you reset nitro amp that is in protect mode?

If the amp is in protect mode, then there may be a speaker wire that is shorting out or you may have a bad can test this by completely unhooking the speakers on the amplifier and then turning the amplifier on...if it comes out of protect mode then you will need to find out which speaker is bad...if the amplifier does not come out of protect mode when you turn it back on then there is a problem inside the amplifier and you will need to take it to a service shop for further diagnoses

My amp overheated and entered protect mode and I smelled burnt wiring what do I need to do

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. Hopefully you have warranty . Please check speakers prior to connecting another amp. .A thumbs up would be greatly appreciated if this answer is helpful to you

The red protect light is coming on

It is possible that your amp is going over the threshold limit of draining current to give out the protect signal. What could be done is to first checkout if your speakers are loading the amplifier, check the rating of the speakers and the impedance, must not be too low.below 2 ohms. Now check the source signal if this is bringing in any transcient signals to power out the outputs particularily high/low freq. So decrease off your bass and treble to mid position and test again. see if there is any improvement, if so there could be a filter problem with your set. Connect an external source and see if the amp powers better , in such case check for fault in cables, input lines and ground with in the set. Repeat this and check. Hope this helps you out. Good day

I have a dual electronics 4 channel amp that goes into protect mode as soon as i throw power to it

unplug all the speaker from amp then power on. if you still have a protect light amp is bad and if you have no protect light continue to hook up each speaker one by one while amp is on till you get a protection light and that speaker would be the source of your problem

Xplod XM-554ZR Car Audio Amplifier: powr/protect light comes on red not green...

Hi, disconnect all speakers from unit and try again - if red light still shows then your amp has died.
If the light goes green, then start testing for shorted speaker/wiring. This includes speaker wiring to vehicle shorts - there should be an o/c reading on your meter

Amp in power protect

Protection Circuit is bad. It needs to be serviced. If all speaker wires are disconnected and it's still in protection, it's got a problem. Hope this helps

Protect light comes on, no power

Hello patrick_h_mi,

You'll also need a remote turn-on source for the amp to operate. Normally, this is a blue or blue/white wire from your head unit, but for test purposes, you just need 12V to the "remote" terminal on the amp. The amp should power up without speaker inputs or speaker connections, but it is not recommended.

Hope this helps.

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.

Protect light

check speaker wire is not grounded and/or the proper impedence is followed. Those amplifiers are 2 ohm stereo stable. Know the difference.

Remove speaker wires and try amplifier.
Add 1 speaker at a time until the problem recreates itself, or test them with an ohm meter.

More than likely, your speakers are wired up in such a manner that they are creating more resistance than what the amp can handle. That's usually what puts amps into protect mode.

Car speakers should be 8ohm's resistance, but if you're bridging and running a dual voice-coil sub or two subs in series... you could have inadvertedly wired it up so the amp is seeing 4 or 16 ohms of resistance? (depending on which way you went)

Try removing the speaker wire completely, then turn the amp/car on and see if it still goes into protect.
