PROTECTION LIGHT CAME ON AMPS. I TESTED SPEAKERS IN ANOTHER CAR THEY WORK, BUT I CANNOT GET PROTECTION LIGHT OFF. I DISCONNECTED EVERYTHING AND RECONNECTED. THEY WERE WORKING FINE, BUT WHEN I DISCONNECTED SPEAKERS TO MOVE THEM OUT OF TRUCK AND PUT THEM BACK, PROTECTION LIGHT CAME ON. dOES IT HAVE TO BE RESETTED OR WHAT DO I DO?
Was the amp hooked directly to the box? You probably rattled the power connections from the circuit board like I did on a PT 800 watt amp.but check amp fuses first.

It sounds like there is a problem with your wiring. Usually the protect on an amplifier comes on when your amp is overheating. The overheating is usually caused by the wrong impedence, or not engouh air circulation. If you have a digital multimete (DMM), you can disconnect the speakers from the amp and measure the impedence. If you do not have one, you should take it to a local car stereo shop. They would be able to test this area for you. If they tell you that you have to buy another piece of equipment, please post the make and model for your amp(s) and subwoofer(s). This also goes for replacement factory speakers.
If you are getting power to the amp, try this....Find a small speaker, unhook your sub and wire speaker to amp. Turn on your system at a low volume....If the other speaker is playing through amp, then your sub is shot.....If the small speaker doesnt work, then its either your channel is gone on the amp or the rcas have quit off off your head unit.
the protection light will come on as a saftey precaution in case the spearker blows or a wire shorts and in some cases if the amp it self shorts check your wiring and if you find nothing take the amp to a auido place and have it tested.
There is a number of things that can cause no sound from the amp.
Check to make sure your RCA's are plugged in to the amp. Make sure the ground and remote are not touching on the amp. This will cause your head unit to gray out in some areas. Verify, your subwoofers are in working order. Test another pair of speakers on your amp to make sure. If those speakers work, your subwoofers are fried or have come unhooked inside your subwoofer enclosure. Make sure you have not set the head unit to Surround Sound if you have a DVD player in your vehicle. This should be set as passive. Make sure your gains aren't turned down on the amp. MAKE SURE YOU DIDN'T BLOW A FUSE UNDER THE HOOD. Even if there is a light on the top of the amp, the fuse might have blown. Make sure a fuse on the amp didn't blow. This will in some cases cause the amp to go into protect and no bass.
I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.
My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.
First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.
The protection light comes on if the amp overheats or if the speaker outputs are shorted.
Turn everything off and check all of your speaker wires for shorts. When you locate and repair the short, the protection light should go out and your amp will work normally again.
