My Kenwood stereo bnn99ih problems with protect off

Kenwood service center can fix this.

If ur kenwood stereo is going into protect mode, it is because one of ur speaker wires is shorting out. Make sure all of ur speaker wire connections are good, and then wrap them so they aren't grounding out against the chassis. This should solve ur problem.

Speaker wires are shorted somewhere.

Check the speaker ohms. If you still have the factory ones they are rated at 2ohms. All new stereos need a 4 ohm speaker. I had the same problem with a different kenwood and all I did was change to a set of kenwood speakers and that fixed the problem

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 have a kenwood kdc-241 car stereo and it has gone onto protect mode i have done everything it says in the manual and even taken it out of the car just in case it was damp i have tried putting it back in but still is in protect mode can anyone help me please

well that means you had a safety stereo in the beggining and you proly didnt put the safety code in so it went into secure mode it to prevent the device from working if stollen

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!

your speaker output is shorting either at the output terminals or at the speaker input . check the cabling . it will solve the problem
