20 Most Recent Kenwood KDC-MP4032 CD Player Questions & Answers


I would use a test light or multimeter and see if you have system voltage at the back of the deck on the power wires. This will tell you whether the problem is with the Kenwood or the wiring and components coming to it. Remember the car has a radio fuse too

"PROTECT" :- The speaker wire has a short-circuit or touches the chassis of the vehicle, and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT" code does not disappear, consult your nearest service center. Reset is a tiny little hole hole to the right of preset buttons along bottom of unit, Insert paperclip to reset to factory settings?
Good luck with it

hi, seeing that your kenwood showed up "protect" you may have an audio circuit/amplifier fault within the unit. try resetting the unit to see if unit comes "on" again. if the unit comes on and protect flashes again, then you definitely have an internal audio circuit fault. if not then check all power connections(yellow and red wire voltages, as well as ground connection), as well as the condition of the face pins!

One of the following procedures to clear the security code should work:

KENWOOD SECURITY CODE CLEAR procedure

Your radio will require one of the following procedures.

Type 1
During the code request mode, while holding the DISP key depressed, press and hold the Volume UP or DOWN key for 3 seconds (so that "..." disappears).
Then using your remote enter your code.

Type 2
Press the "Auto" button and "Track up" on face of radio at the same time. The four dash lines ( . . . . ) should "disappear".

Then using your remote enter your code.

Type 3
Model# DPX-4020 and DPX-4030
Press and hold the 1 then the 6 preset key (preset keys are the buttons on face of radio for storing your "favorite" radio stations). "C" should display.
Then using your remote, enter your code.


Enter your number from the remote control unit. If your code number is 5227 (KCAR)

* Press numeric key "5" ( 2 times ) and press the Track UP/Next Track key
* Press numeric key "2" ( 3 times ) and press the Track UP/Next Track key
* Press numeric key "2" ( 1 time ) and press the Track UP/Next Track key
* Press numeric key "7" ( 2 times ) and press the Track UP/Next Track key
push button "track up" for 3 seconds
The security is canceled and the set enters the TUNER mode.
