SOURCE: Protection

It seems the unit has a thermal overload issue. It could just be an adjustment, or a defective part is going bad. Also try and check all the speaker wireing for pinches or shorts. Also have the speakers checked as maybe one is going bad and overloading the output stage. If you do all these things and it is still shutting down then you have no choice then to have it tested on a bench at a repair shop or replacing it. Good Luck PS Please dont forget to rate this thread.

SOURCE: 12 w 3 v3 2 cut off

Again as I have stated in my other answer to you. You can not wire two SVC 2 ohm subs to acheive a 2 ohm load. more than likely you are running your amp at 1 ohm mono and this is why it is clipping and shutting off.

The ohm load may be too low. What make/model amp is it?

SOURCE: Problem with SAMSUNG HT-X20!!

The fan is going bad and when u play dvd's the spining of the cd is acting as a fan witch is why they play longer then any other mode i had the same problem 2 times the second time samsung wanted 160$!!! thats bull because it keeps going out so what u do is open the case and remove the cover over all the capaciters and whatnot and replace that fan in the back then cut a hole in the top of the metal case directly about the cap's that warm up and install a aditional fan to act as a chimney a little noisy but i did this and the player had been runing in aux and radio mode for a few days stright now no problems at all it's alot of work and skill but for 2 5-15 dolar fans sure beats the 160 for repair or buying a new recever!

My sound plays for a while and then the amp goes into protection


Try a different set of speakers or if it keeps going into protection you have a channel going bad.

Speakers cutting in and out at high volume


The amp is going into protect on the two channels powering the speakers. Turn down the gain on those two channels. You also may want to consider crossing over the speakers a little higher than they are now.

The rating on those speakers are way too high. 6.5's and 6x9's will take 50-100 clean watts tops before they start to break up.

The best solution to get it perfect is....unplug the subs. Turn the gain on the speaker channels all the way down. Then turn up the deck 80% as high as it will go. Play a song. Then increase the gain on the amp until the speakers are as load as they go without distortion. Shut off the car, replugg in the subs and do the same thing. Gain on sub channels all the way down, deck then to 80%, find a bass heavy song, then turn gain up until subs become distorted. If you do this procedure your speakers and subs will be "gain matched" to the proper levels.

Good Luck

Amp shuts off then on


It's getting so hot that it's going into thermal protection. Turn down the gains of lighten the speaker load. The more speakers that hook up to it the more power it will put out causing the amp to overheat. Eventually it will burn up some of the output Mosfett Power Transistors.

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

I bought my g-dec jr form ebay last summer and really like this little amp but this past winter I went to use it, it worked for 3 to 5 min and shut down, but the power light just blinked moderately. I...


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.

Why does my reciver say portect


Does it come up with Protect as soon as you turn it on or does it play for a bit and then come up with protect?

The Amplifier has a Fault and is shutting down to protect itself (If it will jet you play for a bit). Repeated cycling of this will cause a total failure in the Amplifier (If it says protect as soon as you turn it on).

If you haven't got the Technical ability to have a look at it yourself then your only option would be to take it to a service engineer.

There are really only two possibilities here. If you have the gain turned up too high then your amp will get over worked and will go into protect mode. It is a safety feature. You should never really have the gain at much over 50% up. If you have to consistently run it higher than that you are overworking your amp and it will either shut down to protect itself or you will fry it.

Amp cuts off


sounds like you are overheating the amp, if the amp has a fan to cool it off, make sure it is turning on and working... if it is not then replace the fan to fix the problem...also turn the amp gain down a little bit and try running it again and see if it still shuts off...if it doesn't shut off then you have teh gain to high and are cutting out the amp with to much power going thru it...
