I had the impression that I could raise again the volume, do you think when you turn on the LEDs you have to stop or can you still turn up?
If the limiters aren't set to maximum and it is clipping, then set them to maximum.
If they already are at max, more wattage will not be produced by cranking things higher, all you'd get is more distortion and potentially a dead sub or dead amplifier.
Sounds like you need to upgrade to the FP20k or FP14k, as the 10k doesn't seem to be enough power for your application.
21's, 24's and higher-end 18's can consume all the power the 10k has, and still needs more to reach their maximum potential. This is not uncommon to see, and possibly even well-known at this point.
Ideally you'd have 10db of average-headroom to allow for climaxes in songs/movies, 3db headroom at the absolute minimum.
It's good news that it wasn't DOA and hasn't blown up (yet), I suppose... hehe!
The 10k was really intended for speakers, not subs.
But it CAN be used for that, watts are watts.
As I mentioned already, the 20k and 14k has double the power per-channel and 5hz deeper extension too!
Double the power is about a 40% increase in excursion and 4-8x increase in coil-heat, give or take...
If you want to play it safe, you could get one 14k, and if 4.4kW x2 still isn't enough you could get another one and bridge them for 14kW x2. That should definitely be too much... (Too-much is almost-enough!
