Question about Kenwood Car Audio & Video
When the stereo goes into PROTECT mode it is due to a speaker wire having a short circuit or is touching the car chassis somewhere.
Check all speaker wires from the unit to the speakers.
First check that each pair of speaker terminals at the speaker end is not touching. Or, a wire fell of 1 terminal to rest on another.
Best way to check if it's a blown speaker or a wiring short, is to disconnect all speaker connections ( at the speaker end ) making sure the disconnected wires don't touch each other or any metal in the car. press the reset on the unit and power up. If the unit powers up ok, then its a blown speaker.
Otherwise it's a short in the wiring.
If it's a blown speaker, you can connect 1 speaker at a time and the blown 1 will send the unit into protect mode again.
If it's the wiring, disconnect the unit from the wiring and use and ohm meter to check each pair of cables. A reading suggests a short.
If you don't have an ohm meter a battery and bulb will do. This method usually works on a short.
If you have no joy with either method, take each speaker wire in turn and check with a source of earth (anything metal connected directly to the body of the car, cigar lighter main body when pulled slightly out is good)
