Question about Kenwood KDC-MP332 CD Player
My kenwood cd players says protect when i turn on the car and that is all it says and it will not do anything it just says protect
Or you can jus hold the reset button with the radio on until it says standby then try turning the unit on, or jus reenter the code on the unit which is 3214 and try step 1 again

You have a shorted speaker wire or a blown speaker. The unit is protecting itself from damage. Did you install it? if so, pull the deck and check your connections. If they all seem fine, disconnect one speaker at a time, and turn on the radio. Make sure the radio speaker wires are taped so they don't short and cause more damage. Test each speaker wire until you find which one is causing the problem. Now re-connect all the other speakers and test. Next, disconnect the speaker wire right at the speaker that's giving you a problem, tape it off, then re connect it to the receiver. now test again. If all is ok, you have a bad speaker, if not run a test wire from the radio to the possible bad speaker and test again. If the speaker plays, you know what the problem is, replace the bad wire. Most often it's a door speaker wire or a wire got pinched during installation and took a while to short. Hope this helps

Usually, protect mode is enabled when the speaker output wiring has shorted together or is touching ground/+12V. I would verify that none of the speaker wiring has come loose.

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.
