High, My speakers didn't play so I checked my amp. Its slid away stretching the wires in my boot and was in protection mode. I pushed it back into place and it turned on but started smoking so i immediately took it out. after a while i securely places it back in. It turned back on and started working, but then stopped. There was no smoke. When i turn it on now the protection light comes on, and the start light slowly turns on and quickly turns off. what is the result of this??

What size is the amp and how many watts is the speaker(s) you have it ran too? If your speakers are trying to pull too much power from the amp it will turn itself into protect mode to keep from blowing a fuse as well as if you are pushing to many watts into small small speakers it will do the same to protect from blowing the speakers I would recommend turning the settings on the amp down slightly and then trying it out also make sure your wires arnt crossed adjusting the setting as it plays is the easiest way to fix the problem also make sure the bass isn't all the way up on your head unit

It could be a short in your speaker wire or the crossover in your speakers.

1) Turn off your unit and disconnect your speaker wires at the amp, if the protect is no longer displayed when the unit is turned back on, check the connections on the speakers. If you do not visually see a short on the speaker wire connection, turn off the unit and disconnect the wires at the speaker and isolate them so they do not touch then connect the speaker wires at the amp. Turn on the amp and see if the protect is on. If it is on, the wire has a short somewhere in the line. If the protect is off then suspect the speaker has a short in the voice coil or crossover.

2) If the protect is still on after you disconnect the speaker wires at the amp, it could be the power IC in the amp is shorted and needs to be replaced.

if your in protect mode then it is because of couple things one the ground wire is not properly grounded or two the amp is overheating also if the amp gain is way to high it will throw the amp into protective mode try these see if fixes it

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. . Double check all connections. Good luck.
A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.

This is a short or unstable ohm load. Remove all speaker wire connections to see if the amp will stay on.
If the problem goes away when disconnecting the speaker wires try this:
1) Check volume level on zone one and zone 2 if connected. If it is too high the amp will go into protect mode and shut off exactly as you described.
2) Make sure no wires are touching any other wire or the metal surface of the amp. This will cause a short and send the amp into protect mode.

Look for a frayed speaker wires. Look everywhere. Start where you can see and then look under carpet, under seats, trunk and everywhere wires go throgh a hole in steel frame. Any minor connection between the two speaker wires will cause high-power systems to go into protection mode. Wires can be damaged by long-term vibrations of your car, people stepping on badly placed wires under carpet, moving seats (when adjusted) or even rodents bitting on the wiring. Look closely and you will normally find it. Also look closely where you connect your speaker wires to the amp. One small strand of wire jumping across to another terminal will cause a short and cause protection mode.

The unit is in protect mode. A problem was detected in the final stage of the amp and the unit shuts down to prevent further damage to either the amp or speakers. Check the speaker wires to be sure that they are not crossed anywhere. If with the sepaker wires disconnected, the amp still enters protect mode, the problem is internal to the amp. This is usually defective output transistors. Expect a parts cost between $15-$40.

the amp is going into protect mode due to something wrong in the amp or some thing in the wiring to it ooh yea if you are getting 18v power to the amp that is way to high it should not be higher then 15v if the amp is in protect mode it will not play at all.

if the amp is powering on the sub and playing and then turns in to protect mode it could be the amp is getting hot and its kicking into protect so you wont fry the amp

Ground wire too thin.
supply wire too thin.
Speaker damaged.
