How To Get Protect Off Of Stereo

Unfortunately, Kenwood's documentation doesn't always do a good job of explaining this. The manual that comes with the KDC-BT340U, KMR-D372BT and several other models tells you to take your unit to a service center and leaves it at that. The manual for the Kenwood KDC-MP242U is a little more forthcoming. It explains that your stereo's speaker wire may have a short and offers options to fix the problem. The manual for the KAC-M1824BT gives an even more useful checklist. Aside from the potential speaker problems, it explains that the unit's protection can be triggered by overheating, by speakers of the wrong impedance, or by a malfunction in the receiver itself that sends DC power instead of an audio signal to your speakers. Armed with that information, you can start troubleshooting.

check your speaker connections paying attention to polarity. Good Luck

Turn off the receiver and let it cool for a few hours; then try again. If the protection mode warning doesn't go away on its own, press the reset button. If that doesn't work, disconnect the power lead from your receiver for 30 seconds and then reconnect it. If it still doesn't work, it's time to take it to the dealer
