I have a problem with my amp everytime I switch it on, it goes to protect mode. Even without connecting the speakers. What could be the problem?

Power up the ampwith no speaker connected. If it goes into protect mode, the amp has been damaged.
If it is OK, check your user manual for wiring instructions, loading etc.
Do not allow the speaker wires to touch the car chassis/metalwork!

Check it without speaker connection. If the set does not go to protection mode, check all the speakers by connecting one by one at a time and switch the set ON; to find the faulty speaker. If the set goes to protection mode even no speaker connected, check and replace damaged components at its audio output section circuit. If you wish to get some details; check the site linked here.

Disconnect all the speaker connections, and just switch the set ON. Even now the set goes to protection mode, the fault will be with its audio output section circuit. If it does not go to protection mode without speaker connections, check all the speakers. Connect on by one at a time; and switch ON the set; thus you can get the faulty speaker box. http://electronicshelponline.blogspot.com/

Hello
Disconnect all speakers from the set and switch it ON. If it goes into protection mode, surely the device need service. Something shor circuit is with it inside the circuit. If it does not goes into protect mode without speakers, make sure that any one among the speaker connection has some kind of short with the car body of the speaker itself has damaged. Connect the speakers one by one and find out the damaged speaker or faulty speaker line. OK.

I have exactly the same problem, try a different speaker wire from your sub terminal to your amp terminal, if no luck you may have a loose connection on the wires on your sub, due to vibrations etc they can sometimes come loose, but very rare. worth checking though. 1 loose connection can make the amp go into protection mode. If all of these are fine, start from the beginning, ( I have tried this and i think its my speaker wire shorted out) 1st dissconnect all wires from amp. Then connect ground first, then your live. then power up amp, it it works andd not in protect mode your earth and live are fine, then connect your remote, then test, then speaker wire , then test, that way you can rule out bad connections and find any fault.

If the problem is present without any speakers connected, then the problem is with the amp and it needs servicing. If the problem is only with the speakers connected, then search for a short in the speaker wiring. Look for a single strand of wire shorting across speaker or amp terminals, excessively long stripped wire that can short when things are moved, pinched wire under furniture and pat damaged wire. If you have an auxiliary speaker switch box, try the speakers without it as it may have problems with the output circuitry of the amp. I hope this gives you a starting point. Good luck

check it without the speakers if they go to protection,and if not check the speakers

The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

check if it goes to protection mode on power on. see to it that speaker selector switch is set.

Is your speakers connected properly?

Is your music source ok?

Do you hear a click after you switch on the power? the click indicates that the time-on delay transfers the amps output to the speakers which prevents thumps going out to the speakers.

Once it goes to protection mode you need to have it serviced. This is due to a fault in one of the amps and that it protect the speakers from further damage.

'Protected' usually appears on amps or combined cd/amp units when the main processor detects a short circuit in the speaker connections and the unit goes into 'protect' mode to stop further damage.Check the speaker connections. You may then need to reset the unit by holding the power switch in for a few seconds while powering on the mains cord for example. Sony A/V amps are notorious for this issue.
