I've just had the same problem and looking at the above suggestions took the head unit out and what do you know, half of the two part earth wire in my car leading to a crimped joiner had come loose where the headunit had been pushed too far back in the cage by my wife. No big deal, just undo join, put wire back in, tape up with electrical tape and ta-da! Fully functioning head unit again.

The speaker has a short-circuit or touches the chassis of the vehicle, and then the protection function is activated so try to wire or insulate the speaker cable properly and press the reset button.

This is a safety feature and it usually suggest that there is a problem with the internal amplifier, it could also be a trapped speaker wire. Remove the radio and check if any of the cables have been damaged and if you power up the radio with the speaker plug disconnected that will tell you if the fault is in the car or the radio

SOURCE: Kenwood kdc-148 is in protect

A car audio component like an amplifier (or in this case a headunit) is most likely to go into protection mode when there is a short in one of the speaker outputs-- in other words, if the + and - ends of one of the speaker leads are touching, this can cause damage to the internal amplifier of the unit. Some units will respond by putting the amplifier into "protection" mode, so that it does not damage itself. Check connections on the back of your unit, or take it back to the shop that installed it.

You need to switch the aux function back on and to do this you need to turn the radio on to standby and press and hold the menu button for a few seconds and then use the toggle switch on the right side of the fascia to get to aux and then flick the switch forward to switch the aux on

I get a message Protect. All other controls are


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

I have a kenwood KDC-MP438U stereo. Ipod error.


Hi If anything the stereo was probably designed and tested using a certain version of the Iphones software, now that version 4 has been released the way the IPhone communicates may have changed.

As a result the stereo is no longer able to talk to the phone and vice versa. your probably best off contacting Kenwood direct to see if they are aware of this problem and if there is anything that can be done about it.

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!
