![]() ![]() When you've addressed all of these issues, reconnect the battery's negative cable, and turn on your audio system. Consider moving the amplifier if it doesn't have several inches of open space around it in all dimensions to provide a flow of cool air.ĥ. If the amp is hot to the touch during operation, this may be the problem. If the amplifier overheats, the protection circuit is enabled. Check the amp's temperature and ventilation. ![]() Check the speaker wires for bare spots or cuts that may be contacting a ground.Ĥ. A bare spot in the wiring, if it contacts a metal surface, will cause the amplifier to go into protection mode. Check that a speaker wire is not accidentally grounding. Check for loose wires or stray wire strands that may be short circuiting the output.ģ. If bare speaker wires touch each other, it causes a short circuit in the amplifier's output circuit, triggering the protection mode. Check that the speaker wires are not short circuited. Turn off the car's electrical power, and then remove the negative battery cable from the battery while you troubleshoot the amplifier.Ģ.

The protection light usually means the outputs are shorted, but in your case hooking power up backwards probably damaged the protection circuit. Rather, the user must take the time to eliminate the possible causes of the problem that causes the protection mode to turn on. However, after a detailed look into the design of the amp, it is apparent that protons talented engineer was tasked to design the 'sexy' & 'powerful' power amp/PDP section, which is quite brilliant. : Wendry Power Amplifier Board,Horn Protection Circuit,Zero-Drift Output Voltage Stable,Operating Voltage Dual DC for 2SC5200+2SA1943 Power. There is no reset switch or other way to turn the amplifier back on. AV-300 Integrated Amp: This is the one I would recommend people to avoid, yes it got the amazing PDP that up the power when you need it. When the amplifier is in protection mode, the amp ceases operation. Output protection usually appears in a design, sometimes to protect the amplifier from damage by load failure (speaker, wiring, inadequate DIN speaker. Kenwood car amplifiers have built-in protection modes that shut down the amplifier when conditions that may damage the amplifier occur. ![]()
