This is a Sony XM-ZR1852, 1000w amplifier with two Sony 1300w subs plugged into it. All other speakers work fine and the deck is working fine also. I checked all connections to and from the amp, and there were no signs of a loose connection anywhere. The amp turns and lights normally, and I hooked my subs into the home stereo and they work fine also. If there were a blown fuse, the power protector light would turn red but it remains green like when it did work. I'm stumped.

Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.
Some older Pioneer radios require you to connect the Subwoofer RCA to the rear output on the back of the radio and then you have to turn on the subwoofer in the menu on the radio. What model Pioneer radio is it? Also, make sure that the RCA plugged into the amp is on the input side, not the output side.
Can it make them crank? Well, that all depends on your expectations. That amp/sub combo is going to give each sub about 125W, which isn't much. But if it's what you have, it's better than nothing. You might also consider using only one sub and bridging the amp. This would put about 340W on the one sub, which is much more reasonable.
Yes. If the rated power is 380W and the Max power is 1000W then it will handle it. Subs fry when clipping occurs. Clipping is when the amplifier is pushed past its capabilities and the output to the sub gets "dirty". The better quality the amp, the safer it will be on your speakers. It is also important to remember that the gain control on the amplifier is NOT a volume control to boot the sound, it is only to match the output from the headunit to the input handling of the amp. Cranking the gain up too much WILL CAUSE CLIPPING.

Are you certain you put the wires back on the amp the exact way they came off. I am not familiar with this amp but most amps if you look at the terminals where the speakers hook up there will be a plus and a minus. And generally there are four terminals. hence stereo plus and minus left and right. Some even have eight for, four channels. Since the amp is on, not getting hot and you tried two different audio inputs I would suspect speaker wiring or maybe the stuff you put in your trunk bumped a switch on the amplifier. I know this is not the exact answer you are probaly looking for but it is at least a place to start
