Changed speakers and now red protect light stays on? why?

When the "Protection" indicator comes up the display panel of my receiver or the On/Standby LED is flashing, does that mean my receiver needs to be repaired?
The "Protection" light comes on when the receiver's current sensing and thermal monitors detect some unusual operating condition that, if left unchecked, might damage the amplifier. This can happen if there's a dead short in a speaker wire or if you're using very low impedance loudspeakers at high volume for an extended length of time. On older model AVRs you may see the word "Protect" on the receiver's display. More current models will indicate a flashing red light on the Standby LED when a Protection circuit trips
n thermal cases, the circuitry will automatically reset after a few minutes of cool down and the Protection indicator will go out and normal operation will resume. If the protection light came on due to a speaker wire short, low impedance condition or a bad speaker, the receiver's power will need to be turned off to reset it. Before turning the power back on, all speaker wire connections should be checked for their integrity at the receiver side and at the speaker side. If the protection light goes on immediately after you turn on the receiver, disconnect the speaker wires at the receiver side and retest. If the receiver's protection light goes off, then there would still seem to be a problem with one channel's speaker wires or speakers. Connecting them one by one and retesting should allow you to find the problem speaker or connection.
If after checking all your connections, the Protection indicator stays lit, you may need to "initialize the microprocessor (see the FAQ on that topic) or take your receiver to an authorized repair center for a diagnostic. The "Initialization of the Microprocessor" or "reset" procedure can be found in your owner's manual on current model AVR product. Please note, this will erase all setup configurations in the system and require the system to be setup again. You may want to mark down the settings before resetting your receiver to aid in the setup process. If you had an installer setup your system, you can contact them for assistance and any associated costs that may apply to setup the receiver again would be the responsibility of the owner.

The protection light is on indicating a short or over- voltage problem. If you disconnect the speaker leads and the light goes off or green then the problem is a shorted speaker or wiring problem. If the light stays red the problem is inside the amp and it will need service and parts.

try disconnecting one at a time each speaker till the red turns to green. One of your speakers may be bad. Amp is just telling you that its clipping and overheating due to the change in ohms of a shorted or bad speaker. Its also possible the amp is on its last leg due to heat. Heat breaks down electronics part and eventually get worse.

disconnect rca and speaker wire if its still on u may have a problem with ur amp

it may need to be "reset" in which case you just unhook the battery for about 15 minutes. what i wanted you to check tho was the voltage of the battery. 6 or 12 volt

Does it go into protect in the vehicle if you disconnect the speaker wires from the speaker terminals of the amp?

unplug the speakers and the RCA leads from the amp, if the red protection light is still lit then its 1 of your linear amps blown or mosfet depending what your amp uses..if the red light does go off with the leads all disconnected, then connect 1 lead at a time and check the light,when you connect the bad lead or speaker then the light will come on and you know that 1 needs replacing..hope this helps

this is very simple to do just take your face plate off and were you see a red light blinking just get like a bobby pin or something and pit it through the hole and the radio will reset and that should fix your problem

you probably have the speakers set to where it ecxeeds the ohm load limits. its only 4 ohm stable when bridged and two ohm stable when ran using two channels. so either run the speakers at 8 ohms each parallel or just hook one speaker to eack channel. if you do not know what i am talking about then just email me at [email protected] and give me the speaker specifications.

You have a short in the speaker wiring. Simply put, the pos and neg (red/black ends) of your speaker wire are most likely touching somewhere. The receiver has a short protection circuit that keeps you from blowing the receiver or your speakers. Either try re-cutting the ends of the speaker wire, or if that doesn't remedy the issue, buy new speaker wire.
