    Default protect mode ?

    Had the boat out for the 1st time this year after redoing the stereo again, added a harpoon amp, resused the 800watt amp for the incabins and just cleaning up the wiring mess from the patchwork install from last year.

    spent a few hrs in the garage jammin the system and all worked good

    anyway, after wakeboarding and surfing for a little over a hour the headunit goes into protect mode. my wife really doesnt like music loud and it was a sunday morning too-its a smaller lake so I had not been jammin it loud

    stock 08 kenwood headunit

    what is protect mode and how do i get it out of this mode
    I did try shutting the headunit off-no luck
    tried shutting off the stereo switch on the dash-no luck

    Ideas ??

    Thanks

    I have had the same problem from the same Stock Kenwood Headunit 08', except my stereo will work for a couple weeks just fine and then it will decide to go into protect mode. I'm wondering if it just overheats. I only turn it up at about 75% -80% max volume on the hu. Anyways, I found this:

    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.


    Also, I think I had to pull ground and power off to get it to reset. There is a reset button on the hu but I couldn't get it to work for me?

    Daze - do you have the deck powering any speakers directly? or are you just going RCA outs?

    This also happened on my old Kenwood - no rhyme or reason behind it. To get mine to work I had to push the reset button on the headunit, I think it was either on, or behind the faceplate. When I upgraded the problem went away.

    Happened to me once or twice when there was a bunch of stuff in the glove box, I guess it was getting too hot.
