My MTX 600xd amp light won't even come on. ... Red light comes on. ... one.. and some times it goes into protection... once I turn the car off...

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

MAKE SURE THE GROUND IS GOOD ON BODY OF CAR BOTH UNDER THE HOOD AND WHERE YOUR AMP IS GROUNDED

Most of the time. If the protection light is on that means your protected. Not that there is something wrong. So if it is working then your fine.

try hooking up only the power ground and remote see what happens if protection light is on then u have a problem with amp if it goes off then hook up rca if still off then hook up speaker wire if it turns on then u have a prob with speakers

Hi the protection light comes on when there is a problem within the amps. circuitry. Generally speaking the protection light normally comes on when powered up while the amp checks all of its voltage rails so that they all lie within a specific tolerance, when all have been verified to be in spec. then the protect light goes out & the power light comes on. If the protect light stays on then a fault exists within it's circuitry. Cheers, acbva.

The amp has no way to cool itself off, so it goes in to protect when it gets hot to keep from breaking stuff and blowing a fuse.

Eith some wires touched, you dont have big enough fues or you have somehting hooked up wrong

you have your subs wired wrong for that amp!

Check your speakers with an ohm meter. They should have some resistance but not totally shorted. Its prob the amp that got fried. Connect the amp to the battery with no speakers attached to it if the protection light still comes on then the amp is blown.

If the amp is blown you can send it to people on ebay and get it fixed pretty cheap. Good luck!
