Why will my speaker stop playing and go into protection is there a reset bottom

Protect mode comes into play when there is a problem with the speakers or amplifier First check all the speakers for opens or shorts If they are fine you don't reset it you repair the receiver.

First, if you can, try checking all of your speakers and speaker wires for shorts and or grounds. If the speakers and wires check out fine, try resetting the radio. This can be done by pressing the reset switch, which is either an unmarked depression about the size of a pencil tip on either the face or the subpanel behind the face. If there is no reset switch, you can reset the radio by disconnecting the car battery for a few seconds. If the radio still stays in protect, you may have a bad output IC.

you need to check all your speakers first. just because they play don't mean they aren't blown. This protects your radio from blowing out any channels. Once you replace that bad speaker or shorted out speaker, reset the radio and you are good to go.

"PROTECT" :- The speaker wire has a short-circuit or touches the chassis of the vehicle, and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT" code does not disappear, consult your nearest service center. Reset is a tiny little hole hole to the right of preset buttons along bottom of unit, Insert paperclip to reset to factory settings?
Good luck with it

ok, your amp is in protect mode. either the speaker wires are crossed and shorting out, your woofer's vioce coils are melted and the speaker is blown or the amp is dead.

to determine if the speakers voice coils are melted, and thus the speaker being blown is the reason for the "protect" light, simply push in the cone of the woofer in gently with your hand. the woofer should move a little more than an inch, without any resistance, before bottoming out. if there feels to be any resistance, like a rubbing or scratching, before the woofer bottoms out, then your voice coils are fried, and you need a new woofer.

reset the unit you will see a small hole in the front and use a paper clip size hole and if it keeps on doing it you have a speaker going bad

amp goes on protection few reasons
goes on protection, improper speaker connection,improper speaker class, speaker out-put damage (needs to get repair)

you have one of your speaker wires shorted out to the body of the car somewhere, or the speakers that you installed are bad. That is the only two reasons it will go into protect. Correct the problem, then reset the deck - it should work fine.
Kenwood builds this feature in to protect the outputs - so they dont burn up in the case of shorted speakers or wiring.

Overload protection circuit kicked in. Check all your wires (speakers,input,output cables), There is a short somewhere and lets hope it's not In the receiver.

This happens less often in "normal surround" mode
