Which amp is the best SQ out of these CLASS D choices, assuming all of these
you could get for the same price, which would you choose and why? I'll be
running a sealed box with probably infinity kappa perfect 12.1D or Fosgate
Hx2 punch.

We need to know what sub and voice coil configuration you'll be getting
before we can help. One amp might be better at the load your sub will show
it than another.
