Hi I see your post was never answered and I doubt you still have this amp.. Many amplifiers are tossed in the trash due to this one little mistake! But for future use and I hope it helps: Install inline fuses on both polarities negative and positive, it is very important not to exceed twelve inches from your battery Reason: after this length resistance starts. to develop thus causing your amp to work harder and cause it to overheat and shut down and yes the red light will be on letting you know... Hey I'm a little warm after I cool off ill turn on again but I probably wont sound the same.... Thermal shutdowns,reverse polarity,low voltage,remote wire installed after ground wire all these mistakes cause the switching transistor to short out n throwing the amp in protect mode!! your local CB shop should be able to help you out next time I've been around amps since 16 yrs of age now I'm 37 and still trying to loose my hearing!! haha lol... hope this helps but remember always hook your positive cables remote, bat, mount amplifier, - batt , last the RCA cables...

If the positive power cable touched the ground, the fuse inline should have blown. Did it?

Installed lanzar 266 amp yesterday it went in protect mode on a song and now everytime i turn it on it is in protect mode


most commonly that means that somewhere there was an arc in the electrical either the pos or neg going into the amp or rcas or its the speaker wire from the amp to to the sub itself look especially for little wires touching opposit polarity wire (like a little +wire has moved and touched a - wire)

Has an internal issue, if you know how to use a ohm meter, check the resistance of the wire on the interior of the amp, also check the fuses, ground, and power wire clean up the ground wire where it is connected to the vehicle

Protection circuit.
Checek the wiring of the amp and speakers, don' forget to look for shorts at the speakers. Make sure no wires are touching each other

Light


The red light indicates that your amplifier is in protect mode. Amps go into this mode if there is something wrong with the setup of the system to prevent fatal damage to the amplifier circuitry. This is bad thing since the amplifier will not function until the problem is solve and it can remove itself from protection mode.

Amplifiers can go into protect mode for many reasons but one of the most common is incorrect mounting. Is your amp sitting on the metal of your vehicle? Is it bolted down and screwed into the metal of the vehicle or your seat? The amp should never be touching any sort of metal. Only the ground should touching the metal of your vehicle.

Speaking of grounds, many people often neglect proper grounding which can cause an amp to go into protect mode. Do you have a solid ground? Is the wire less than 3 feet long and directly connected to a non-painted metal part of your vehicle? Is the ground wire the same gauge as your power wire?

These are just a few reasons why an amp can go into protect mode. You can find more information here. Or simply google for why your amp is in protect mode.

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 Mode with RCA's


It sounds like you have some DC voltage on the RCA input.

You need to figure out if the problem is coming from the head unit or if it is in the amplifier.

If you have a voltage meter, you can use it to find out very quickly.

Set the meter for DC and for a max level of more than 12 volts. Most meters I use have a 30 volt level. That would be a good setting.

Take the black lead and make sure it is grounded to the chassis of the car or to the ground of the power terminal, be careful and make sure it does not touch anything else.

With the RCA cable disconnected put the red lead on the inner part of the RCA cable and see if there is any DC voltage and then check the ground or outer part of the cable. Do the same for the other channel as well.

It should be very close to zero volts. A couple of millivolts is fine to. Any voltage here will cause the amplifier to go into protect mode, which is what is happening to you. You will then need to have the head unit serviced.

If you have a Pioneer head unit, I have seen many of them with an open ground fuse for the RCA jack. That fuse is a surface mounted fuse and is very small and hard to locate on the main board of the radio. If you do have a Pioneer head unit the voltage may seem OK, but you will have an open ground, but that normally does not put the amp into protect. It makes the audio sound very weak and you would have a loud hum. I can help you with that if it turns out to be the problem.

If the voltage on both the RCA leads is OK, then you need to check the amplifier.

You can put the meter lead on the ground of the RCA jack on the amplifier, if you have anything abnormal there, you have a problem in the amplifier. Be careful checking this because you can easily touch the lead to the chassis of the amplifier at the same time as the RCA ground. Most of the time, if yu have a problem in the amplifier like the one you are having, this check of the RCA ground will result in some DC voltage on it. If it still checks OK, then put the lead into the RCA ground and check the positive part of it. You may need to move the lead around a little to get it to touch the metal inside, it is on the bottom part of the hole inside the jack.

I think you will find that you have some voltage on the RCA inputs of the amplifier. To fix this properly you will need to take it in to be serviced.

Sometimes you can ground the RCA jack ground somehow with a jumper wire and then turn the system on with the RCA cable plugged in and it will seem normal. But you do not want to do that as a repair, only to see if the amp will play. If it does play, you know that the problem is in the pre-amp of the amplifier. That would be the only reason to connect an external ground to the RCA jack. You still have a problem in the amplifier. If it does not play normal, you still have a problem in the amplifier if there was some DC on the RCA jack.

Sorry this answer is so long, but the problem you are having will require service of one of your units, you just need to know which one it is. If your inputs get grounded, you will not have the amp go into protect, you just won't hear anything.

Let me know if you need more help and if this was helpful to you a good rating is always appreciated.

Diamond Audio amplifier 1200W


If the speaker wires touched and the protection circuit didn't engage quickly enough, the output transistors may have failed. This is the most common cause for an amplifier to go into protect mode.

If you disconnect the speaker wires from the amp and the B+ and remote voltage are above ~11 volts (place black meter lead on ground terminal of the amp when checking the voltage), and the protect light still comes on, the amplifier will need to be repaired.
