Re: SUB PULLS IN INSTEAD OF PUSHING OUT
In a normal subwoofer it does pull in and push out to create the sound.
It could be that the voice coil is damaged (by over excursion running
it into the magnet) and it now can't push out past a certain point hence looking like it's pulling in. Push in on the woofer with your hand, do you hear a scraping sound? If
so it's time for a new sub. If not, take it out of the enclosure and
push out on the cone from the inside, scraping now?
Another test for loose voice coil windings that I find works is the
hold the sub up close to your ear and bang on the magnet with the palm
of your hand, if you hear faint rattling or anything other than a low
"thud" sound then there's is some sort of mechanical failure within the
woofer............also time for replacement.
If all seems good at this point, try connecting it to a different amplifier, the sub itself may be fine. If you've lost one of the amplifier rail voltages the sub will pull in but not push out...(or vice versa depending on if it's the positive or the negative power rail)......and yes, it would sound distorted.

When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.
What's the exact model of your amp? For taking the higher frequencies/treble out of the subwoofer, the amp should have a little button on the side that says "Hi Pass" or "Low Pass" or maybe an adjustable knob-thing that says "X-Over". These will set a cut-off frequency for your sub output. Some amps don't have this feature, but many do.
u should connect at least six 12" subwoofers (preferably 1000W each) to that pioneer amp of yours. Crank it up and enjoy. Your amp shouldn't cut off now. If it does cut off, you should change the fuse on your amp to a higher ampere.
Buy an amp wiring kit. The battery cable goes to the battery (duh, right?) with the fuse within 18 inches of the battery. The ground gets bolted to a clean section of the car chassis/body. the remote lead goes to the radio's remote out (blue/white stripe). the rca cable goes to the radio's Sub/rear RCA outputs. Speaker wires go the speakers. Done!
This may have a different type of triggered turn on wire. On some of the older Pioneer amps (and maybe some new ones) the trigger wire would SUPPLY B+ TO THE RADIO and when the radio was switched on the amp would sense a current draw on that wire and would then switch on. Unlike most common amps which sense the presence of B+ on the trigger wire supplied by the radio and then turn on. Look in your owners manual to see kind of turn on system you have. If you don't have an owners manual then perhaps you can download one from Pioneer support.
Your battery should be fine! Although the amp might not be strong enough for the sub. All you can do is check the RCA cables from your radio to your amp as these might vibrate loose when you get to 17 volume and also check the monster cable from your amp to your sub asit might have vibrated loose as well.
