My Kenwood KDC-MP438U Says PROTECT, and I can't figure out how to get it to work

Could be a short circuit on your speaker output, try disconnecting all 4 speaker wires and then power up. Otherwise its the audio amplifier circuit that needs to be replaced ( audio IC )

Protected mode means that there is a speaker wire that is grounding out on the chassis, another wire or another wire. Check all the wire connections to make sure there is no loose wire that may be getting grounded out. After it's insulated properly and reconnected, hit the reset and you'll be back in business. k

you must of traped a wire when you have fitted the head unit to the car when you have pushed it into the dash or the call wire is going to earth on something behind the radio in the dash hope you fine it hope ive help you let me now how you get on

if its a newer truck it will most likely have a factory amp u either have to utilize or bypass

you need an aftermarket PAC!


it will work just fine!

You need to unplug the unit from the back and find the problem. Usually, it is almost always your speaker connections. Once you find the problem within the speakers, plug it back in and it resets it.

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!
