The "Protect" message indicates that the unit has detected a short or surge in the wiring to the unit. Check your ground and make sure that the speaker wires are not the problem. (Any broken wires or speaker wires that touch the case of the CD player could cause the issue.)
If there are no obvious wiring problems, then the unit has an internal short. That should be resolved by sending the unit for service if it is under warranty.
Please add a comment with the model number of the CD player for additional information. I hope this helps.
A speaker wire has a short-circuit, crossed, or touches the chassis of the vehicle it activates the protection mode function.
? Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT" code does not disappear, consult your nearest service center.
I have attached a link for you which is for a free Kenwood KDC-MP443U instruction manual download. Nice receiver by the way! Kenwood KDC MP443U Instruction Manual
make sure you have no bare or shorted speaker wires and check your speakers to make sure they are all good. if that all checks out, you probably have a bad output ic.
when its hook up press the tiny reset or go online to kenwood for the mater reset code for the model reciever you have that is a security feature kenwood has on its stereos when they are stolen only thing it doesnt know when the battery dies on a car or is removed. anyway kenwood has a master or check you manual. the preset station number are what you press for typing in the code.
"Protect" isn't for security on a Kenwood; it's caused by a problem with the speaker output. There may be a defect in the CD player, or you may have a blown speaker or a shorted speaker wire in the vehicle. Try disconnecting all the speakers and see if the unit still shows "protect" when you turn it on. If it still shows the "protect" message with no speakers connected, the unit needs to be serviced; if not, re-connect the speakers one at a time until you find out which one is causing the problem.
