Hi my amp ( Earthquake Mono block 2000 watt digital amp TNT t2000wd1 IS haveing a problem with the protection light going on..i guess it all started when i took a hard turn my amp is bolted down so nothing hit it but idk what happend...i removed all wiring and just had the wires to power it up and still had the protection light on...could it be that i have the wrong 2 fuses connected cause i bought new ones which where 25's and i dont got the manuel to double check it.
When you made that hard turn your volts on your amp drop, cause it to go
on to protection? and also your driving the amp with not enought current? steady 13 volts you need!!
the fuse on the amp are just to protect it, you should always fuse it with another line fuse
same ratting 50 amp!! what ever the size it has on the out side..
If that does not work send it to the factory ..
Same thing happened to me a while back it is one of the reistors inside the amp, when you took the turn it anything bumped it or it fell it might have broken off, shake it and see if anything inside rattles, if so then you need to take it to a repair shop or some who can solder

What is the speaker load in Ohms that you are running? Or what exactly is hooked up to it? are you bridging it? The protection light will come on if the load is too much for the amp to handel. If the load (in Ohms) is less than the rated load that it can run, it will stop the output to keep the amp from self destructing. The amp will sense that the demand for power will be too high for the amps circuitry which will either make the amp get so hot that it will burn up the copper on the board or more likely burn up the power mosfetts that power the speakers. If the Ohms are within range then it will allow power to flow through the circuit until the rails that the mosfetts are bound to until they get so hot that it will go into thermal protection. So if your amp has both thermal and overload protection lights and the overload is light then the load is probably too much for the amp. if it's bridged in mono the you can only have 1 speaker setup hooked up it if it's a 2 channel amp. a 4 channel amp bridged in mono for both front and rear channels will be able to have 2 speakers rated a 4 ohms each hooked up to the amp 1 set per bridged output or channel. Try it running in stereo with only 1 speaker per channel and see if it will produce sound. If not then you have an amp that has internal problems and will need to be serviced. Check your warranty to see if you are covered.
The high current drain due to a possible short in the sub output drivers must have pushed the connectors to melt off and fail.
Your amplifier driver MOSFETS might have shorted to bring about the protection on. Make sure that the wiring to the sub woofer is not touching a ground or shorting.
You can ask any audio tech. to have a look within and test for shorted driver outputs.
Hi the protection light comes on when there is a problem within the amps. circuitry. Generally speaking the protection light normally comes on when powered up while the amp checks all of its voltage rails so that they all lie within a specific tolerance, when all have been verified to be in spec. then the protect light goes out & the power light comes on. If the protect light stays on then a fault exists within it's circuitry. Cheers, acbva.
Two things, a problem with the speakers, or the amp is toast. If there is a short is the speaker, wire touching, bad voice coil, the amp will go into protect. I have also seen many, many MTX amps that go bad, and just stay in protect. the easiest way to check, is to unhook the speaker wire from the amp, then power it up, if it still goes into protect without a speaker hooked to it, you have a bad amp. Hope this helps.
probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.
No, this amp is not a heavy power consumer- matter of fact it takes very little power to run.Maybe you should check the fuses on the amp to see if they are what is recommended.Also check your fuse kit to your amp- your fuse might not be big enough.If neither works take it back where u got it.
