Kenwood in dash cd player

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.

Speaker wires are shorted somewhere.

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage, or a bare wire touching the body of the car

Hi,

Kenwood head units show "protect" when there's a problem with the speaker outputs. This might mean a shorted speaker wire, a blown speaker, or an internal defect in the head unit. Once the condition that's causing the "protect" mode is fixed, the CD player should be back in normal mode the next time you turn it on.

If it's staying in "protect", then you'll definitely have to remove the stereo and do some troubleshooting to fix it. Many car audio stores will do system troubleshooting, for a fee. If you want to do it yourself, here's what you need to do:

Pull the Kenwood unit from the dash and disconnect all the speaker wires. Turn it on and see if the "protect" message displays. If it does, the stereo has an internal defect and will need to be serviced. If it doesn't, then turn it off, and re-connect one speaker. Turn it on again and see if it displays "protect".

If it works with a single speaker connected, keep re-connecting the others until you identify the speaker that's causing the problem. There may be a wiring problem or defective speaker in that location.

If it displays "protect" with a single speaker connected, then disconnect that one and try a different one. If all the speakers cause a "protect" mode, then you're probably back to a defective head unit, unless your friend managed to blow all your speakers at once.

Thanks,

i installed this strero in my car and all i get is the word protect .now what do i od

Today i brought a 98 ford and the dealer replaced the cassette player with a Kenwood KDC-MP6036 from a trade in they had. It was fine for 30 min approx then music stopped and "PROTECT" was displayed and now nothing works ???? what can i do

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.

" protect " is flasing on my w534 cd player and my cd player will not work any more . any ideas
