That depends on the particular application and the specific amplifier.
An open boat requires more power than an enclosed vehicle cabin.
A strictly regulated amplifier will get it done with less power than an unregulated amplifier.
A 10" W6 doesn't need quite the power as a 12" W6 even though the thermal capacity might be similar.
In a boat, and given the conservative power ratings by JL, I like to go to the very top of the thermal rating, and often more with an unregulated amplifier.
CEA-2006 ratings are way too easy to be a realistic measurement of actual performance. 14.4 volts which you won't have. At 12.5 volts you might drop 25% or more power. 1 kHz which is just an upper midrange frequency. You could easily lose another 20% at 20 Hz. On multi-channel amplifiers you may see another major drop with all channels driven versus one channel driven. At 40 Hz with all channels under load with a 12.0 V supply you could easily be half of the rated power.
Usually with experience a shop/dealer settles into combinations that they know to work well together. And that becomes their 'go to' package. Sometimes you try something and your expectations aren't met based on previous experiences with a given woofer. You make the change and your pleased.
So again, start with the thermal rating as a minimum threshold. Know that you can exceed that by some margin with good results and long term reliability if the system execution is right (design, tuning, etc.) and you know how to take care of your possessions.
