Open Question

Good evening, my car amplifier is in protect mode and doesn´t leave it, i already check the rcas and speakers output and didn´t work thing i notice was that when the voltage was on -12v the amplifier work, but when i start the engine the amplifier entered in protection on 14,4v..but i conected it on a power transformer that on stand by hit 15v to make a test and since that point it doesn´t work, not even on 12v..could anyone help me? thank you

    could you give a more details on your statement:

    " notice was that when the voltage was on -12v the amplifier work ",

    what do you mean by -12V ?

  • raphael_mart Oct 02, 2010

    Palaboy, sorry that error, what i mean is - 12v..i already put the amplifier working, i found out that the overvoltage protection was the problem, when i put 14v on the remote, the sistem think it´s something like 17v and enter in protection, so, i put and variable resistor on the remote and i adjust it until it start..i didn´t touch the board, i don´t know what to replace.

    i notice that the plus simbol didn´t show up, i mean "minus,plus 12v."

SOURCE: Protection Light irritation

If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.

SOURCE: Rockford P550.2 going into protect mode

Have you tried using bigger gauged wires? If the amp can not pull enough power through the wire it can cause it to run into protected. This solved my problem running a 2000W amp on 12 gauge wire, went to 8 and it worked great.

SOURCE: Protection mode

It's normal for some amps to go into protect for a few seconds when initially powered up. If it remains in protect mode, it may have shorted output transistors. To eliminate other possible causes, read through the following troubleshooting page:

Let me know if you have any other questions.

SOURCE: amp goes dirctly into protect

ok well it could be two thing wrong your amp dont have a good ground or your amp is a smar amp and your subs must have to be hooked up so the power from the amp cn go to the subs so the amp can see that you do have subs hooked up to take it out of protect o and look at your fuses to to smal or to big will send it to protect to

NAD M3 power light turns red immediately and PROTECT message displays. Amp keeps functioning but volume control doesn't work up or down.

Check the connection to speaker with this amp, for any short or any other fault. disconnect the outputs, ie, speakers from the amp, and switch it On, and see the protect display comes or not. If it comes, the fault is internal and the set need service.
Your M3 dual Mono integrated amp, is of high output power and its outputs are protected against any overload or short circuit. If the system detect any among this condition specified above, it will show protect mode display.
Never load this amp, as protection display is there, as it may damage the speaker or its internal power amplifier section circuits, may cause more money to get it repaired. OK.

Pioneer VSX-D511 5.1 Channels Receiver over heated and now won't turn on?

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be with your output drivers. Please check for short on the outputs fitted for both the channels. Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise which can be a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board. Maybe the protect circuit by itself is shutting off due to a faulty bias or there is a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the amplifier comes out of the protect mode then check for short on the speakers.

My Harmon kardon is stuck in protect mode

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. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

Short light is on how do i reboot it

You can't reboot an amp. If it's an internal short then unless you take it to a repair shop, it's pretty much dead. Try unplugging all the speaker inputs/outputs first and just leave the 12v wire, remote wire and ground wire connected. Turn on your radio and if the protect light goes out, then there's a problem with one of your speaker input/output wires and maybe your RCA wires. If removing all the speaker wires worked, plug in one at a time until it kicks into protect mode which will tell you which input/output wire or speaker is shorted. good luck

It goes right to protect mode when i plug in the rcas

plug one at a time to check for a short on either the right or left channel. if both do it, then try another rca cable. if that does it too, then unplug your speaker outs and plug your rcas back in and check. get where i'm going with this. process of elimination. if nothing helps, then there's a short in your amp.

How can i get my amp out of protect mode?

Disconnect all wires - then reconnect ONLY...


At this point a protect fault means the problem is internal, and the amplifier must be repaired.

If it powers on normally - add the RCAs
If protection at this point - the RCAs may be damaged bare to ground. Replace the RCAs.

If still operating normally - (and after checking the voicecoils on the speakers are within specs with a multimeter) add speakers to the normal rated impedence of each channel.

Amp went to protect mode and will not reset to green.

Be sure the rca's are not getting severly pinched or worse you drilled a screw into them.

Second make sure your connecting the RCA's to the
1. OUTPUT of the radio
2. INPUT of the amp

if you connect any other way its wrong and could damage both radio and amp especially you screw into the RCA's your sending 12 AC Volts to ground.

Amp powers on, no sound from subs

the output is blown. It is in need of service.
There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause.

Negative speaker output touched chasis of amp.

check all fuses on the unit, pull them all.
look for a way of resetting the amp.


that way you wont short a screw driver across the terminals on to the chasis.
