First of all the amp was playing then it start it to shut down in protect mode but would come back on an play again. then the last time it stop playing it stay in protect mode and was making a ticking sound. someone told me the outputs were bad so i replace the transistor that look to be bad but the nte 2395 that replace the factory install blew as soon as power came on and now the fuses are blow as soon as power is connect to the amplifier. how can i get the right parts for this amp like power supply and output switch.

Also could be that the power wire and earth wires going to amp are to thin amp could be heating up and could be going into protection mode. Will switch on after it cools down what gauge wiring are you using?
Ok because your wattage is too high for the amp when adjusting a amp with speakers always start like this turn amp gain all the way down head unit bass all the way down and treb all the way up then turn on ur highest listening volume that u like then ajust amp to that hight if will stop protect from happening if continues ur sub is too many watts for amp ok
This amp uses a TDA2050 chip that has thermal protection. It is also a small amp that is NOT capable of high sound levels. If *********** can't stand to be within 5 feet of this amp you are playing TOO LOUD for this amp and it will shut down until cooled off to protect the amplifier chip. This amp is intended for practice. It would be adequate for sensible listening level in a 10 foot by 10 foot room. If you need more sound you will have to get a bigger amp. I would suggest you get a sound meter and verify the sound level. DO NOT exceed 4 hours at 90 DB... I know a lot of deaf musicians that have lost their hearing and they are not much good anymore.
might not have enough voltage going to the amp. depends on the size of the power wire too. had the same problem with mine, had to upgrade my wires, i couldnt turn it up past 14 with out it shutting off and then back on.....
Amps shut down due to, A: Short circuit, B: Overload. C: Over Heating. It is possible that the Output devices inside the Amp. get too hot during use, Are your speaker "Leads" "Big" enough? Is you Power Positive wire the same, Also as you say, Check your Earth. Sometimes a Fan on the output devices helps.
The amp is being overworked and is overheating so it is shutting down to protect itself. You could try to add a fan and point it at the amp to help keep it cool. Also make sure the amp is not located where it will get heat from an exhaust pipe under the car for example. They may have external fans that you can attatch to the amp to help cool it. The constant overheating could eventually damage the amplifier.
How long will the bass play before the amp kicks into protection mode and how loud are you listening to it? I've noticed with my amps that if they don't have enough air flow they will get hot and kick into protection mode. They will also kick into protection mode if you are running it at more than it can handle. Check your adjustments on both your amp and the head unit. Make sure you are not running more bass than the amp can handle.
It is most likely an amplifier problem. I had this problem before. It went into "Protect" mode and shut down. When I turned it back on, my left channel speakers made a buzzing noise and did the same thing again. I got it diagnosed at an electronics repair shop and they found that the two STK amplifier IC's were bad. One is about $106 and the second one is about $78. I got it fixed for about $200 and works basically like new again.
