SOURCE: amp cuts off
You may have a problem with the power source feeding the amp. You need to check the voltage across the amplifier's B+ and ground terminals when the amp is playing/cutting off. If it's dropping below ~11 volts, you need to determine why it's dropping so low.

Power is rated at 1000x1 @ 4ohm.
How many voice-coils does your speaker have? If more then one, are the coils wired in series or parallel? How many ohms are the coils? If you actuate the cone with your hand, do you hear any "scraping" sounds?
Assuming everything above is within range and or tests good, the amplifier more then likely has at least one failed output transistor. a DMM would be needed to check for shorts.

SOURCE: Alpine PDX1.600 amp cuts off
Make sure there's no missmatched impedance. If your sub running 2 ohms then your amp has to be 2 ohms stable. Does the amp blow fuses or get really hot? If it does it can be a fire hazard and I would recommend taking it out of your car. It could be that you don't have sufficient grounding. The grounding needs to be very close to the amp and the paint needs to be thoroughly scratched off. Otherwise could be a blown transistor within the amplifier, you can check this by opening up the amp, running a multimeter and testing the transistors for resistance.
