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...

the light stays on because the amp is still storing power. it only turns off when the capacitors on the inside have drained off all the extra power

Mtx 801

The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing. Also check the grounding.

the light with the power light(middle) is a blue/purple faint light try checking it out at night.The squiggy(as heat waves) will only light when the amps shuts down due to thermal protection(wait for it to cool). The bolt/yellow (short circuit) will light when there is an electrical overload in any of the wires(check +ve leads).

Sounds like the amp is going into Protection Mode. Does yours have green LED light then RED LED on it? The green is power and the red is Protection. You will need to either change the OHMS wiring or Put A Fan on it to Keep it Cool Inside.

need to replace the power supply

I run one sub on my Kenwood Amp also. It does over heat also. My conclusion is that we are both trying to push that one sub too hard and the amp is having to work really hard to make that sub do what we are asking. Also, not having enough power or a good ground will cause it to over heat. I am going to go with the voice coils are heating up though.
