    If it goes into protect with no speaker wires connected to the speaker terminals and no RCAs plugged in, it likely has shorted output transistors. Read through the following page if you want to try to repair it yourself. Let me know if you have any other questions.

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.

It probably has a fault.But try this.Disconnect all speakers and inputs and try again.If that works reconnect the speakers A PAIR AT a Time.That should lead to the fault.If that still shuts down.

the set is going into protection mode. This is caused when ever one of the many sections of the tv has a shorted circuit. The increase in current is detected by the protection circuit and it flies into action by turning OFF the ON relay.

Most often, but not always, it is either the high voltage section or one of the deflection amplifiers. But can be the power supply, the audio amplifier or voltage regulators, etc.

Red protection light wont turn 2 green no matter what so the amp wont work

Hello mcis43fan,

The protection circuit can be activated by shorted or grounded wiring or it can be caused by a defect in the amp itself.

First, disconnect all wires except power, ground and the remote turn-on lead and see if the amp powers up normally. If it still goes into protection, the amp is defective, most likely shorted outputs and needs repair or replacement. If the amp powers up normally, test the other wiring for shorts and grounds. You can reconnect them one at a time to determine which one is causing the problem.

Hope this helps.

My Kenwood amplifier is having problems, whenever i turn it on. all seems well until i play some music through it, after 30seconds to a minute the music will cut off and a distinct click is sometimes...

Your amp is going into protection. The click you hear is a relay meant to protect your speakers and stereo. Check your speakers with an ohm meter for the the proper ohms ( listed on the speaker ) and physically try to push each woofer and midrange cone in gently to make sure it moves and is not stuck or frozen in place. A speaker may read correctly on an ohm meter if the woofer is ok but if the tweeter or midrange is not working it will cause the amp to go into protection mode. When you play music stick your ear up to each tweeter\midrange\woofer to ensure they are working.
Your stereo could also be the culprit although usually if it plays music it is ok as long as you are not hearing loud pops. Loud pops are voltage spikes that indicate that a transistor\IC is breaking down and will eventually short. Good luck!
