I would check to see if you have a secure ground and check all of your connections for shorts.

I have a kenwood kac-9152d amplifer and it works just fine for about 10 minutes then just shuts off and subs dont work, about 30 seconds later my amp turns back on with the subs.


make sure it's well ventilated. If there's no air flow, then there is no way of cooling down and to protect itself it will shut off. Make sure the speakers are wired correctly as per amp specs. too many subs or subs connected improperly can draw too much current and shut the amp off, but you will notice this when you turn up the volume to a certain point and the amp shuts down.

When i turn up the volume my amp shuts down i turn it down and it comes back on. I have a crossfire vr1000d what am i doing wrong?


Hi,
Is the protect light in your amplifier turns on when it shuts down? If yes, then your amplifier lacks voltage. The reason why it goes on protect mode is, the amplifier is needing an amount of voltage from your car, since your car cannot provide that amount of voltage your amplifier is not getting anything, instead of getting voltage to produce watts its getting minimum voltage & producing heat, to save itself it goes on protect mode so the incoming power shuts off & cools the amplifier.
Example:
Your on vol 40, amplifier is working fine, when you turn it up to vol 50 your amplifier shuts of, then you put it back to vol 40 & your amplifier turns back on.
At vol 40 your voltage is 12v or above. but in vol 50 your voltage drops to 11 & below.

Check your battery or alternator if they are giving enough voltage


Hope this helps your inquiry. Have a blessed weekend.

I have a JBL GTO 7001, it switches in an out of protection mode. i pulled out the amp, an noticed that the positive wire from the speaker was pulled out. so i disconnected the power scorce an reconnected...


Make sure that your positives and negatives are lined up correctly. This happened to me during my latest install and the problem was I had one positive speaker wire plugged into a negative speaker terminal. This switches the amp on after a few seconds and then back to protect mode once it detects a faulty speaker wire. Hope this helps!

I hooked up 2 capacitors into my amp and every time I put power to it the amp shuts off and 10 seconds later a red light comes on for 5 seconds and the amp don't turn on, basically it goes into protect...


Well, I have no idea why you would have two capacitors on a 500 watt amp but, did you charge the capacitors? Have you tried the amp without the capacitors? What size power wire are you using?

When I connect my power and ground leads the amp turns on for about 3 seconds and the light goes red and it switchs to protect mode. The speaker and rca wires are disconnected


You have a faulty output device(s)... If there is NO LOAD, then you have an internal problem, the Amp "Thinks" it is sensing a "Short" and is shutting down, to "Protect" itself...

Unit only stays on for 4 seconds then turns itself off.


This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.

MY AMP TURNS TURNS ON THE PROTECTIVE MODE


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.

Amp turns of after 2 seconds of turning on


It is going into protection mode, and shutting itself off. You have a short somewhere. I would suggest taking it to an authorized service center for assistance. This is not easy to diagnose, as it could be anything causing the short.

Try disconnecting everything from the unit, including the speakers, and turning on again. This will just confirm that the problem is the amp, and nothing external. Also, try connecting it to a different power supply/socket.
