This is a safety feature and it usually suggest that there is a problem with the internal amplifier, it could also be a trapped speaker wire. Remove the radio and check if any of the cables have been damaged and if you power up the radio with the speaker plug disconnected that will tell you if the fault is in the car or the radio

A "PROTECT" message/display normally indicates a problem with your speaker or your speaker wires. Pls check for any open or shorted (busted speakers) or if any of the wires are touching the chassis/ground.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
Thank you for using FixYa.

A car audio component like an amplifier (or in this case a headunit) is most likely to go into protection mode when there is a short in one of the speaker outputs-- in other words, if the + and - ends of one of the speaker leads are touching, this can cause damage to the internal amplifier of the unit. Some units will respond by putting the amplifier into "protection" mode, so that it does not damage itself. Check connections on the back of your unit, or take it back to the shop that installed it.
