Check all your speaker wiring. Plus make certain the speakers are in good working order, and that low ohm speakers are not connected to it. For example if the unit says 8 Ohm, don't connect 4 to 6 ohm speakers.
If that doesn't solve the problem there's a fault in the main power amp.

SOURCE: need help

Have you connected an extra pair of speakers?. (Thereby loading the amp stage beyond it's capacity)
Are the speakers connected to the unit the original ones the system came with or different? ( Speaker impedance, usually displayed at the back of the speaker cabinet must not be less than amp's specifications....6 ohms, 8 ohms)
If you're driving the unit excessively you're lucky this piece is equipped with protect mode, else your speakers and amp would have been fried by now.
One last possibility comes to mind: High volume causes vibration causing loosely fitted mains plug to rattle in wall socket calling "protect" due to improper feed voltage. Move the unit to another wall socket and ensure a tight fit into mains receptacle.

Hi snark63

Ypou have an intermittent problem that sounds to be heat related... the more work the amp does, the more heat generated by the output stages. This will be aggravating some poor solder joints that are cracked or dry. The unit needs some repair work done in these areas. If you have good experience with a soldering iron, the cure for this is to resolder the power stages of the unit, or any other solder joints that look to be failing.

SOURCE: my pyle amp keeps going into protection when i turn my music up and play it for a min

The most common cause is an unsafe load/speaker impedance. If you have the speakers wired correctly, you may have a short in the wiring. If the wiring is OK, the amp is likely defective

Let me know if you have any other questions.

When I plug my headphones in why doesnt the sound come out of the headphones?


Where do you plug in the phones? if it is an iPhone. the music playing will be stopped, just to precent your ears to be damaged. When plugging in headphones, while the volume is high, the sound level can be so high, you can damage your ears. Yes damage that will last the set of your life, because loss of hearing, can't regenerate. For that reason some MP3 played, cill stop music playing, as soon as a headphone is plugged in.
Just start the music that was playing when you did lower he output volume if the music stops.

Well i was driving one day and my subs just whent out so i bought brand new wires and hooked everything up but the power protector light turns red whenever uu turn it up past volume 10 i really do not know...


It sounds like your amp is going into protection. I know it's frustrating, but this is actually a good thing. If you subs you have are drawing too much power and the amp can't keep up, it will shut off instead of melting the board. Usually, the protection mode only last a few seconds. The user normally turns the music down that the protection shuts off and the music plays again. I recommend looking at a larger amp for your subs, if you are going to play them that hard.

Suddenly, amplifier stopped giving out sound. Controls and display seem to work fine. If it is blown fuse, where is it & how can i replace it?


Does it stop on both channels? It sounds to me like the safety circuit is activating. This usually happens when either the volume is too high, or the speaker load is too great (i.e. usually loads less than 4 ohms will do this) or, the amplifier has an internal short causing the amplifier's output stage to become un-balanced. Does the sound come out nice and clearly through both channels? How long does the receiver play before the sound stops? How loud are you playing the music when it stops like this? If the sound is reasonably clear through both channels at regular volume, then there is probably nothing at all wrong with the receiver's output circuits. If the amplifier is being played at regular volume or even lower volume for quite a while and then quits, perhaps the receiver is getting too hot and it's thermal sensors are activating the protection circuit. Make sure that when you operate the receiver, that there aren't things laying on top of it blocking the unit from venting and cooling properly. Make sure it has plenty of breathing room - amplifiers (most of them anyway) are inherently subject to producing heat. If the amplifier only quits when played at high volume, well then that's probably the problem - it's probably not meant to deliver such power that you're asking it to - especially if you're driving a heavy load such as 4 ohms or less. If you're running several speakers on this unit, try scaling back to just two speakers for now, and make sure these are 8 ohm speakers. Play the unit for a while and see how it does.

Samsung eternity wont play back sound


I had a problem similar to this a few times and found that it was due to the phone thinking that there was still something in the headphone jack so the only sound that would come from the phone was a ringtone or when using the speakerphone. To fix it you can plug in and unplug your headphones (while playing music) until the external sound playback comes back. Hope this helps!
