I am installing a kenwood cd receiver kdc-mp205 every thing is hooked up but the screen says protect wat is the problem?


Hello.. sorry to hear you are having problems. With the Kenwood car stereos, when they detect a bad speaker in the car, they go into protect mode to keep from burning up the outputs of the stereo. Either you have a bad speaker in the car or a speaker wire that is touching metal (grounded out). You can cut all of the speaker wires loose at the radio and reset the radio. Then turn the radio on and hook each speaker up one at a time until it goes into protect and that will let you know where your problem is located. Hope this helps and good luck with your venture!

Hi , i have bought a car with kenwood kdc-mp333 audio player. i get an error protect all the time i turn it on. could u tell me how to solve this problem


More then likely it has an anti-theft system built into the radio. They only thing you can do is try to contact the previous owner if that isnt possible look for a really small reset button.

MY KDC-MP3342U SUDDENLY STOPPED WORKING! IT JUST KEEPS FLASHING ...'PROTECT'! REPEATEDLY! HELP!


Protect only comes on when an RCA is grounding out, speaker is blown or the speaker wires are shorting out. Check all your wiring on the head unit and see if all are insulated with tape or better and if there's an exposed wire, tape it up. Make sure that all connections are secured. Then double-check your fuses. Check all of your speakers and their wiring because going into protect mode is the units way of saying you have a problem with your speakers or wiring.

If your speakers and wiring all check out, disconnect your radio wiring harness, and then reconnect the harness. This resets your radio, and your radio should be working again.

If you need to enter the security code, try the default unlock code of 5227.

You can also try to reset your code if the default doesn't work. Try 'KCAR' or '3051'.

I have a kenwood excelon kdc-x790. i had it installed yesterday and when wired up it did nothing. But when I had another kenwood a cheaper version installed it worked fine. The kdc-x790 that I got was...


If the screen did not even light up, then you definately have a power issue. Verify that your fuse did not blow, and then that you connected the correct wires. The power wires are usually orange and red. Red being the "always on" and orange being the "switched source".

My kenwood kdc mp332 car cd player is saying that it is on protect and will not play anything. how do i get it on and off protect?


if the power is not turned on (or it is on, but will be off immediately,) the speaker wire may have a short-circuit or touched the chasis of the vehicle and the protection function may have been activated. therefore the speaker wire should be checked. the press the reset button. also it will do that if it gets hotter than 60 degrees celsius or 140 f
