Kenwood KDC 241 SA car radio keeps displaying 'Protect'. The manual says it is a speaker wire shorting out. Is it ALWAYS the speaker wire shorting, or are there other causes?
Thanks
You could have a shorted speaker wire, a blown speaker; or the output ic in the deck itself could be bad.
if the car itself limits the voltage, this could definitely be a problem. most radios shut down if the voltage gets below 9 to 10 volts. if it limits the current, that could be a problem also.

My original Clarion radio 'lost' the radio station after around 20 minutes. 'Experts' blamed the radio and advised fitting a new radio. This Kenwood is that new radio (now about 5 days old).
Guess what? Protect mode comes on after about 20 minutes.
I suspect that the 20 mins limit for both radios COULD be tied in with some malfunction of the 'Economy Mode' built in to Peugeot 406's.
So in short, the speaker wires are fine, the speakers are fine, and the unit is brand spanking new.

My original Clarion radio 'lost' the station after about 20 mins. 'Experts' said to fit a new radio. I fitted this brand new Kenwood radio cd.
Guess what? The 'protect mode' comes on at around 20 mins. I reckon that with both radios limits being around 20 mins, that the problem lies with the car and it's stupid 'Economy Mode' setting, which turned off the power to the original Clarion after 20 mins of listening with the ignition off. I had to start the engine to get the radio to play again. i think it's a wiring loom, computer problem.
