Yeah plate amps suck, and 12's aren't very loud. I'm not surprised you can clip it.
People around here tend to clip multiple 14000w pro-amps, not because they are weak, but because they are THAT crazy.

F-15's from DIYSG are pretty decent for the money. Most people just go with those.
Movies really only sound good with high effeciency speakers, especially behind an AT screen. At 108db/w the SEOS in the F-15, it definitely has that...
It will also increase your mid-bass and transition nicely into the 460's, and it will also reduce the load on the amplifier to minimal-levels.
The nu6000dsp is a pretty decent amp for the money, it can drive 4 460's with ease. In fact you'll probably want to set the power limiter.
Keep in mind that all amp companies overrate their stuff, and doubling of power is only 3db louder, so it is best to GO BIG if the price difference isn't high. The headroom prevents clipping and keeps the amp cool by not being overworked.
As far as overheating and clipping goes, there are only 2 amplifiers I've never been able to overheat: The ICE-1000 and the FP14000.
ED LT-1300 plate? Overheated!
Velodyne Digital 3kW plate? Overheated!
My lust for MORE BASS seems unending...
You'll definitely want to service fluffy behind the screen. (Why does that sound so dirty? haha!
There will be a fair amount of resonance their that would benefit from absorption.
I believe trapezoidal side-walls are best, because they are symmetrical but not parallel. I don't think you'll have the width for that and probably don't or can't rip up those.
When I moved my downstairs had an unused fireplace too, I took a sledgehammer to it to reclaim the space.
Threw the bricks in the back of my truck and took it to the dump. Laid all new carpet, gained about 3ft of floor area in my case.
The good news is that brick is better than drywall at blocking bass from leaving the house, so you may want too keep it there.
If there is any glass, I'd took at removing it before the rattles drive you crazy.
4 460 have almost enough output to break drywall. It will have a decent amount of chest-kick for action explosions, horror jump scares and rock music.
You could probably drive 16 460's with one nu6kDSP, if you had to...
Given the option, it is always better to double the number of cones, rather than double the wattage.
It doubles the surface area, cuts the needed excursion in half. Which means: louder and less distortion.
Where as throwing more power at the problem just increases heat and distortion, and while in-theory they should both add 3db, you'll not likely get it by overheating the coils and amplifier, where as doubling the cones you for-sure will get the 3db!
Of course you'll still need some "reasonable amount" of power to push the subwoofer array.
The inukes are cheap, have decent efficiency being Class-D (runs cool and monthly bill won't be high), they have XO/EQ DSP, and they have adjustable power limiters. So it makes sense why the 6000DSP is so popular. You can customize it to nearly any load or power rating (within reason).
It has enough power to drive nearly anything (except maybe high-end sealed 21's, 24's or 32's.)
