Re: SHUTS IT SELF OFF
You may be using 4 ohm speakers on an 8 ohms rated amplifier, or you
are trying to play the amp excessivly loud for its design apability,
or the amp is not strong enough for the speakers, or there is a fault condition where the output stage is pulling too much power, and the protection circuit is kicking in, because of one of these faults. It is also possible that the protection circuit has a fault condition.
A quick test,though. Disconnect ALL speaker wires from the receiver. Turn on the receiver - if the volume increase makes it cut off, the problem is definitely in the receiver.
You should give the amp to a qualified shop that has the proper test
equipment to properly diagnose the amp for its power rating over the
complete designed response, and do an evalution of its dynamic head
room and dynamic range, to see if it meets specs.
If something is out of specs, then it can be serviced.

This sounds like you are overloading the system and the automatic shutdown is working to prevent damage. Is it very loud when it shuts down? Many systems have a built in speaker protection circuit that will disconnect them if your turn the volume up to high to prevent damage to the speakers and the amplifier.
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.
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.
That a new one for me, it just goes full blast huh? I don't have an answer for that, but your amp can shut off because of a lot of reasons.
One you might not have enough power running to this amp. Check to make sure your amp gain is not turned all the way up, this is NOT the volume for the amp. It's to get your amp and the head unit on the same page (i.e. if the radios at 50% volume and so is the amp) if you turn it down too low that will make the amp very sensitive to volume adjustments, and your amp will be at 100% while the raidos at like 50 or 75%. And once you go past the 50 or 75 on the radio the amp, it's going to keep trying to play higher even though its already maxing out which is going to cause it to clip and cause distortion untill it goes into protect mode. Common mistake with a lot of people.
Two you might check all your wire connection to the amp. Three internal damage. The list can go on and on as you can see. RCAs might be damage or even your remote wire. Upgrading your alternater and battery can help.
Some people would even say to check your car factory amp (some times in the trunk or in between body panels) to see if it is bypassed. If it is not bypassed it could be a posability to shut down the other amp caused by to much power causing it to shut down. hope this was helpful
If the amplifier isnt burned out, there is a good chance that one of the speakers is improperly wired, causing a short circuit. The amplifier is tripping the fuse to protect itself. These fuses **** themselves every time you shut off the unit. At very low volumes, the amplifier doesn't detect the short.
test you speaker maybe there is a bad connection some where is the spk. box its self ,try changing speakers left to right . it the spk. are ok open amp see all the connections within the amp . if this dose not work contact me by mail: [email protected]
i had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.
Receiver shuts itself off at certain points of DVD's. I can power it back on and rewind the disc and at the same point it will shut itself off again. Volume can be at zero and the part of the movie is not loud, for instance, at the beginning of Pirates of the Carribean 3 where the boy starts singing before he is hanged.
It shuts it off with no particular reason..
