How do i turn on the subwoofers through my kenwood radio model number KDC-MP142/CR it said to hold the AM- button for 2 seconds i did and it did not turn them on and it does not show subwoofer levels or anything about subwoofers

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 you "favorite" radio stations). "C" should display.
Then using your remote, enter your code.


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

My kenwood is stuck completely in protect mode. I ve everything listed and it wont come out of it. So should i assume the unit has gone bad?

make sure you are getting power to the red wire.

Hold down the AM- button for a few seconds and the sub option will turn on and will be part of your equalizer and you can now change some extra settings on the sub to.

Hey i had the same problem and i've just solved it you just gotta reset the radio the button it´s between the FF button and the 1 button gotta push it with one clip or something like that

get in to "menu" (hold magnifying glass), scroll to "demo mode" (am or fm button), push volume knob in and hold for about three seconds. Should work, that's how I did it.

Hello swanaprslc,

It sounds like the "always hot" or battery wire is not connected to a 12V constant source. If you used a wiring harness, check and make sure that the pin in the harness that connects to the "yellow" wire coming from your Kenwood MP142 is hot with the ignition off. If you did not use a wiring harness, make sure that the yellow wire is connected to a fused 12V + constant source.

Hope this helps.
