Usually the protect is a safe mode to indicate that your set is unsafe. Starrt by checking the speakers, speaker wires for shorting. detach the speaker lines and power on the set for confrimation. check in power/auxially circuits in the set. it is possible that your mechanism drive / audio output drive Ic's could have shorted. Most of these cirrcuits have an error detection of higher current to cut off power and issue a protect warning. so discoonect the IC power to confirm. Hope this helps. Good day

Testimonial: "The problem was with speaker wiring.Thanks"

    Use the reset button to clear the condition. There may be no electrical issues.. My kids friend plugged her iPhone into the USB jack incorrectly at first.. there was probably a brief short or over current condition which latched the Protect circuity.. The Reset button cleared that and monitoring the stereo showed no signs of damage or shorts...... The reset button for your unit should be documented in your Users Guide... If reset doesnt clear the condition then refer to the message above from caroldong who is the GURU !!!

    Thanks the speakers had indeed shorted. There is also a reset button which can be used if the problem was temporary.

My Kenwood KDC-U453 cd receiver displays "PROTECT" on connection and nothing works - any solutions appreciated!!!!


Pull the radio out, tape off all wires but yellow, red and black. Twist red/ yellow together and attach to positive 12 volt, attach black wire to negative 12 volts. Turn on radio and see if it comes out of protect mode. If it does, you will have to troubleshoot all of the speaker wires to find a short.

I have a kenwood it says,kdc-mp142 and all of a sudden it just says protect. it wont do anything


The Kenwood radio will generally give a "PROTECT" error if the amp or receiver is being overloaded. This may mean that some of your wiring may have gotten frayed, one of your speakers isn't putting out the right voltage, or the receiver has decided to go bad. Make sure all of your connections in the back of the radio are solid and not frayed. If that's not the problem, try running each of the speakers one at a time. If one causes the radio to go into protect mode, that's your culprit.
If neither of these are the issue and the radio decides to stay in "protect" mode, your receiver may have seen better days and may need a replacement.

I am installing kenwood kdc-mp443u. it is flashing protect and i can't remove it. can you help please?


A speaker wire has a short-circuit, crossed, or touches the chassis of the vehicle it activates the protection mode function.
? Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT" code does not disappear, consult your nearest service center.
I have attached a link for you which is for a free Kenwood KDC-MP443U instruction manual download. Nice receiver by the way!

Protect code


make sure you have no bare or shorted speaker wires and check your speakers to make sure they are all good. if that all checks out, you probably have a bad output ic.

I would also check the speaker outputs from the deck. If any of the speaker outputs are touching any metal on the vehicle, it could give that message.

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!

Protect:- The speaker wire has a short circuit, or touches the chassis of the vehicle, then the Protect function is activated. Wire or insulate the cable properly and then press the reset button. If the "Protect" code does not disappear, consult your nearest service centre.

"Protect" isn't for security on a Kenwood; it's caused by a problem with the speaker output. There may be a defect in the CD player, or you may have a blown speaker or a shorted speaker wire in the vehicle. Try disconnecting all the speakers and see if the unit still shows "protect" when you turn it on. If it still shows the "protect" message with no speakers connected, the unit needs to be serviced; if not, re-connect the speakers one at a time until you find out which one is causing the problem.
