Disconnect all speakers (at the amp terminals) and the RCA's leaving just power, ground, and remote connected. Does it turn on now without going to protection? If so, plug in the RCA's. Still good? If so, you have a shorted wire or bad speaker. If it still stays in protection, the amp is faulty. Have it repaired or replace it.
Unfortunately, no one knows or is telling. Companies rarely state power in RMS because Peak Power is a much more impressive. 1000 watt amp, 200 watts RMS x 2 channels at 8 ohms. Look for a sticker on the unit.

The wiring is bad on the plugs and shorting out, or whatever is on the end of the cable has an issue. Also look along the cable for rodent, cat, dog chewing.
Questions like this need 'make model (what is is) of every item involved. On a vehicle 'year make model' as well.
The bad ground causes the amplifier to go into the protect mode. So, make sure to check the grounding wire and overall connection to figure it out and set back the amplifier to its normal mode.

There are a few solid state fuses inside but if the speaker wires were shorted then it required an authorised Pioneer service centre to repair the damaged amplifiers section.
first check all the power connections verify every thing is hooked up correctly. check the fuses. and the amp has to have a separate wire called remote going to the back of the head unit. the head unit sends a signal to the amp to tell it to turn on when the head unit is powered on.
