Mostly if you can keep it under 1% ..... which pretty much all Solid state amps will have.

Cuz the Orion HCCA-D5000 has a S/N ratio @ 59db, where most amps i seen are 98-100db?

Oh opps, I was thinking THD%

You want Signal to noise ration to be over 75dB at a minimum most of the time. In the lowest bass frequencies it's less of a problem.

For the most part, depends on the sub, x-over freq. and the listener.
