This could be caused due to the impedance load being to low. Your amp is stable to 2 ohm load however its very possible that you have your subs wired to a 1 ohm load that would cause the amp to go into protect mode. The subs you have are dual 4 ohm voice coils and would need to be wired in series/parallel. I've included a link that will show you how the subs should be wired.
Most likely the ohm load is too low, if you have the subs wired in parallel rewire them in series and see if that resolves the problem. if not then you do not have enough battery power to support the draw that the amplifier pulls. if the vehicles voltage drops below 11.5 volts the amplifier will momentarily shut off, similar to how the lights in your house dim when the a/c cuts on due to the sudden power draw. hope this helps. p.s. if you cant afford another battery right away, lowering the crossover frequency to around 65hz will greatly reduce the amount of current necessary to keep the amp pumping. (in my opinion it sound better that way anyhow.)
On most Pioneer's, there is an option in the main menu that allows you to turn the sub-out on or off. This must be on to let a signal pass from the head unit to the amp. Check this, and if it is on, try replacing the RCA cables. Let me know if this helps :)
It can be many things it possible the amp cannot handle the 4 ohm load and simply goes into power protection mode. Also make sure your using the correct gage wire to run power from your battery to the amp to thin and it wont have enough power to perform.
Are you sure the polarity is correct on the sub's connectors? This is very important as reversing them will cause the sub to pound inward instead of out. Make sure the wires are thick enough and that the amp's + connector goes to the red(or +) connector on the sub and that the amp is grounded properly to a clean piece of metal on the car's body. This ground wire should also be as short as possible. Also make sure the fine-tuning for the bass level on the amp is adjusted correctly and that the sub's enclosure is the correct specification ie. Ported or sealed, right size, etc.
I Had the Same Problem I just unplugged my amplifier changed the fuse, also i had a fuse in the battery cable and changed that, unconnected the RCA wires and plugged them back in and then put new fuses in and plugged everything back into the amplifier and it worked again. If that doesnt work get back to me i will try to help you.
Unplug the inputs and outputs from the amp (be sure to mark the wires so you can hook them back up), leaving only the ground, +12, and remote wire hooked up. Now, turn it on. If the amp light goes red, the amp is broken. If it goes green, turn if off, plug in the speakers, then turn it on. if it's red, its a speaker problem, if green, do the same with the inputs, and you'll have your answer.
