I get protect error on my car stero, can u help solve the problem. Thanks, VJ

The "PROTECT" message is associated with an audio output issue. This is usually a shorted / damaged / mis-wired speaker output wire(s) between the the radio and speakers or external amplifier, but may be a damaged output transistor inside the radio.

Carefully inspect the speaker output wires of the radio. Make sure all are intact, insulation is not chafed, stripped or otherwise damaged. Tape or repair when found. Double check the wiring (if this is a new installation) to be sure it is correct. Rewire as needed.

After making repairs, power up the radio and see if it works. If it does not, damage has probably occurred inside the radio as a result of the damaged speaker wiring being allowed to exist too long or turning to volume up for even a relatively short period of time. It can also happen if connected to very low impedance speakers. Any of these conditions can cause internal components to fail. The radio will probably have to be professionally repaired to play as expected again.

Hopefully, you'll find and correct a speaker wire problem and it will play again. If my reply was helpful, please rate it "4 thumbs up". Thanks & good luck!
